Can the seven "scenario clouds" of Unicom Cloud enable users to realize the freedom of cloud computing?

Not long ago, Unicom Cloud "went out of the circle" and deeply cultivated the legal profession, and "Tianfu Central Legal Cloud" was officially released. Tianfu Central Legal Cloud relies on Unicom’s cloud capabilities, and integrates new generation information technologies such as 5G, big data, Internet of Things, artificial intelligence, blockchain and security capabilities to create a secure, credible, cloud-integrated, self-controllable, cloudy, collaborative and customized digital China legal service intelligent cloud.

In fact, government and enterprise organizations from government, medical care, manufacturing, education, finance and other industries have chosen Unicom Cloud "going to the cloud" one after another, and used different "scenario clouds" of Unicom Cloud to meet the needs in various business scenarios such as municipal services, epidemic prevention and control, medical image storage, smart city security, smart travel, building supervision and so on.

The competition in the cloud computing market has always been fierce. Why can Unicom Cloud stand out from the crowd of cloudy manufacturers and become the first choice for government and enterprises? What is the "scene cloud" of Unicom Cloud and what are its advantages?

The development of cloud computing enters the deep water period, and the acceleration of Unicom cloud runs out.

In recent years, the development of cloud computing market in China has entered a deep-water period. The whole industry has gradually shifted from choosing Internet and IT enterprises to traditional government and enterprise organizations, and the market structure has begun to change. The cloud computing brand of operators represented by Unicom Cloud is growing like a bamboo, and gradually gained a place in the cloud computing market.

Why did this market change happen? The main reasons come from two aspects:

First, Unicom Cloud has continuously cultivated its internal strength and given the market full confidence with its excellent strength. From "Wo Yun" to "Unicom Cloud" with brand rejuvenation, China Unicom has forged an integrated cloud computing product integrating network, hardware, IaaS, PaaS, SaaS, terminals and services after 13 years of tempering.

Nowadays, Unicom Cloud has not only grown into a unified computing base to undertake China Unicom’s big computing business, but also a full-stack capability cloud that can support the digital transformation of all walks of life, so Unicom Cloud has become an important pole in the cloud computing service market in China.

Second, the needs of traditional government and enterprise users to access the cloud are different. They no longer aim at low cost, but pay more attention to how the overall solution of the cloud empowers traditional applications and enhances the degree of intelligence and digitalization.

Based on this, the competition of cloud vendors has also moved from the simple IaaS infrastructure level to the comprehensive comprehensive cloud platform service capability of IaaS+PaaS+SaaS, and the competition behind it is the ability to solve practical problems in diversified business scenarios. On the one hand, it tests whether cloud vendors have complete PaaS functions such as cloud native, big data, artificial intelligence, Internet of Things, etc. On the other hand, it also requires cloud vendors to have fast and perfect solution service capabilities and implementation delivery ecology.

Today, Unicom Cloud can provide more than 280 IaaS and PaaS products, support billions of IoT connections, provide more than 40 artificial intelligence atomic capabilities, 8 blockchain universal service components, and aPaaS components support more than 160 self-developed applications to meet the general needs of various customers.

Not only that, Unicom Cloud also took the lead in proposing a "scenario cloud" in the industry, which encapsulates and uniformly outputs cloud components and cloud capabilities that combine innovative technologies such as 5G, artificial intelligence, big data, Internet of Things, blockchain, trusted security, etc., and forms a number of digitally competitive and integrated cloud solutions, aiming to provide a landing solution for the segmentation scenario needs of traditional government and enterprise users in digital transformation. For this reason, the "scene cloud" has also become the starting point for China Unicom’s rapid development and landing industry.

Seven scenario clouds, allowing users to realize the freedom of cloud computing.

According to Pang Yufeng, director of the product technology department of the operation platform of Unicom’s Digital Cloud Computing Division, the release of the "scenario cloud" product not only integrates China Unicom’s professional capabilities in cloud infrastructure, big data, Internet of Things, AI, blockchain, etc., but also combines the needs of customers in various industries to extract various general scenario capabilities. It is not only suitable for a certain industry, but also from a more subdivided business scenario, which is more grounded in meeting customer needs.

Intelligent video cloud can fully empower multi-scene video applications from three levels: "cloud network intelligence technology integration, product platformization and application scenario", and provide a unified and open interface to meet the needs of multi-scene video surveillance applications. First of all, intelligent video cloud can support public cloud, central cloud and hybrid cloud deployment, and quickly integrate AI atomic capabilities; It can also be deployed flexibly in a modular and modular manner according to the video surveillance requirements of smart city construction. Secondly, support security mechanisms such as HTTPs security protocol and AES video encryption to ensure data security; It also supports the flexible expansion of resources and meets the requirements of massive surveillance video access and high concurrent processing. At the same time, it can provide intelligent detection, analysis and early warning services by adapting to intelligent AI applications such as personnel intrusion, crowd statistics and mask compliance.

Therefore, the intelligent video cloud can well meet the requirements of "seeing, storing, managing, controlling and maintaining" of video surveillance, so as to promote the construction and networking application of public safety video surveillance, and explore the implementation of off-site supervision characterized by remote monitoring supervision and early warning prevention and control; Coordinate road video monitoring, community monitoring and other systems, perceive urban elements such as traffic trips, ecological environment and urban scenes in real time, promote the construction of "Zhi ‘an Community" and "Zhi ‘an Unit", and innovate the intelligent social security prevention and control system.

As Pang Yufeng said, "scene cloud" is like a cloud computing "supermarket". Customers can freely buy and mix whatever they want. The technology behind the scene cloud solution can be "loose and coupled", which can not only meet the individual business needs of industry customers, but also provide a package of overall solutions, so that users can fully enjoy the freedom of cloud computing.

Thick accumulation and thin hair, the scene cloud empowers thousands of industries.

With the deepening of industrial digitalization and the continuous enrichment of application scenarios, the launch of Unicom cloud "scenario cloud" is just the right time, and a large number of customer cases have fully verified its market value. At present, Unicom Cloud has served more than 20 ministries and more than 300 large enterprises, including network services, cloud, big data applications and security services.

According to the latest report of IDC, in the third quarter of 2021, the market share and revenue growth rate of Unicom Cloud Public Cloud ranked first among all manufacturers, providing strong support for the digital construction of eight vertical industries, including government affairs, medical care, industry and education.

Behind the recognition of "Scene Cloud" by industry customers, it reflects the unique advantages of Unicom Cloud. First of all, it has inherent network advantages in computing power and cloud network, and can provide unified services based on cloud network convergence; Secondly, Unicom Cloud’s powerful system integration capability can drive industry eco-partners to jointly build "Scene Cloud" into a highly integrated product solution, with rich application functions and consistent use experience, so that government and enterprise customers can use it with more peace of mind and meet the actual needs of current government and enterprise customers. Thirdly, Unicom Cloud’s stable and reliable operation and service capabilities are unmatched by other manufacturers. The granular after-sales service teams all over the country and even at the county level have also brought peace of mind cloud operation services to government and enterprise users; Finally, China Unicom has long been deployed in government and enterprise markets all over the country. No matter cloud services or applications, it was the first to participate in the innovation industry. In terms of technology, it realized the independent control of the core components of cloud computing and the adaptation of mainstream domestic software and hardware. Under the guidance of domestic substitution and independent controllable policies, Unicom Cloud, as the national team, brings security and credibility, which is favored by government and enterprise users.

All in all, Unicom Cloud has both top-level planning and technical capabilities, as well as experience in delivery operation and personal service. As a tool to finely serve the digital transformation of government and enterprise customers, "Scene Cloud" is becoming the "killer" for Unicom Cloud to build its own core competitiveness.

Starting from "Core", test drive Changan Yidong 1.4T Blue Whale Edition.

  [car home Original Test Drive] Looking back a year ago, when the second generation of Changan (|) was officially listed, the stunning appearance made you stunned. I have to say that such an exaggerated and bold design really conforms to the public’s aesthetics, and Changan has made its own style. After a year, Yi Dong Blue Whale Edition came to us again. Although it didn’t surprise us in appearance this time, it quietly changed inside.

Home of the car

  Changan Yidong Blue Whale Edition’s 1.4T engine this time comes from Changan Blue Whale NE power platform, and it has more backbone in the face of competing products. First of all, let’s talk about Changan Blue Whale NE power platform, which is positioned as a medium and small displacement engine. Under the effect of modular concept, it can be compatible with engines with displacement between 1.0L and 1.8L. If necessary, it can also be equipped with front-end technologies such as 48V, PHEV and ethanol fuel, and it also meets the increasingly stringent national VI emission standards.

  The 1.4T engine of Changan Yidong Blue Whale Edition has a slight improvement in parameters compared with its own 1.5T(156 HP /225 Nm), and has certain advantages compared with competing products, even better than the engine book data of some joint venture brands. In terms of transmission, it is equipped with a 7-speed wet dual-clutch gearbox.

  The book data of the engine is excellent. What is the actual performance? Theoretically, the maximum torque of 260N?m starts to break out at 1500rpm, and the low torque should be good, but the engine is more willing to pull the speed above 2000rpm, and it is the stage of its force after intuitively feeling 2000rpm. Earlier torque burst can make up for the lack of low torque of small-displacement engines and create a lighter driving experience. At the same time, the accelerator pedal is light and sensitive at the beginning, and it is easy to follow cars on urban roads, and basically the second half of the accelerator is not needed.

  This 7-speed wet dual-clutch gearbox has good ride comfort during daily driving, and there is basically nothing wrong with daily driving except a little setback in frequent switching between the first and second gears. Although the power connection of the dual-clutch gearbox is not as smooth as that of the AT gearbox at the beginning, according to the performance of most dual-clutches in the market at present, the gearbox mounted on Yidong is indeed slower than the common dual-clutch gearbox.

Changan Automobile Yidong 2019 1.4T Automatic Blue Whale Edition

  At the intersection of traffic lights, the green light lights up to release the brake, and the power connection of the gearbox is a little slow. At this time, you have to give a foot of oil, and it will start slowly and leisurely. If the throttle is given too much, it will run forward again. Especially when turning around, frequently switching between D and R gears, the gearbox always feels a beat slow. When accelerating rapidly, the first gear rises to the second gear and even has a power vacuum period of about 1 second, which wastes a lot of acceleration time.

  After speeding up, the gearbox seems to have changed its personality, judging the driver’s intention more accurately, and being able to shuttle through the city with a 158-horsepower engine. After engaging in the S gear, the throttle response is more sensitive, and the engine is willing to stay at a high speed and wait for your instructions, but there is a process of power transmission to the wheel.

  Yidong chassis has a good thick feeling and solid feedback. In contrast, the adjustment of the suspension is mainly based on comfort. The small bumps on the daily road surface can be well resolved, and it can be easily dealt with in the face of speed bumps. However, when passing at a faster speed, the longer suspension stroke will still have some redundant jumps. In addition, the lateral support force of suspension is not its strong point, and the body roll is more obvious in fast doubling and cornering.

  The steering wheel is moderate in size, full in grip and light in steering, which is suitable for female drivers. However, the strength of the steering wheel will not sink with the increase of the vehicle speed, and it will not sink after being engaged in the S gear. You need to hold the steering wheel tightly when driving at high speed.

Changan Automobile Yidong 2019 1.4T Automatic Blue Whale Edition

  In terms of noise, it has a certain improvement compared with the old models. When driving at a speed of 80km/h in the city, wind noise and tire noise can be controlled within a good range. When driving at a high speed of 120km/h, the engine speed is high (2600rpm), and the engine noise has certain influence on the front passengers.

  The new 1.4T+7-speed dual-clutch powertrain with Yidong Blue Whale version is still biased towards urban households, so it is difficult for you to find sports characteristics in it. In fact, the manufacturer knows the positioning of this car very well. It is just a family car. Treat it gently. It serves you proudly. If you drive hard, its performance may not make you so satisfied.

Is zeekr Krypton 001 rich in safety configuration?

Zeekr Krypton 001 has a very rich safety configuration.

First of all, the car body adopts the industry-leading cage body structure, and the A-pillar, B-pillar, roof frame and other parts are made of thermoformed steel, which is 3-4 times stronger than ordinary steel, and the top pressure bearing capacity can reach about 11.5 tons, which can effectively disperse energy to prevent the deformation of the cabin during collision. There are also a number of collision force transmission channels, such as sub-frame, wheels, lower A-pillar, etc. When the frontal collision is 25% offset, the positive 45-wheel unloading mechanism will be activated, which can control the deformation area and guide energy during high-speed rear-end collision. The steel-aluminum hybrid body structure with ultra-high strength thermoformed steel and 7 series aluminum alloy is adopted, and the torsional stiffness reaches 40000 N m/deg.

Secondly, in terms of battery safety, based on the concept of pure electric drive, the high-strength design of battery and body structure is realized. The battery has passed more than 100 system-level and more than 200 parts tests, far exceeding the national standard. The polar battery pack adopts NTP non-thermal spread prevention and control technology, and has six safety protection measures, such as early warning, which can intelligently cut off power and prevent overcharging.

In addition, the active safety configuration is rich, and it is equipped with two 7 nm Mobile Eye EQ5H intelligent driving chips, four 2-megapixel panoramic cameras, seven 8-megapixel high-definition cameras, a driver fatigue monitoring camera, a 250-meter ultra-long millimeter-wave radar and other top intelligent driving hardware, which can improve vehicle perception in all directions. For example, when driving forward, the FCW front collision warning system can monitor the range of 150 meters ahead in real time, and judge that there is a collision risk, which will remind the owner that the AEB active emergency braking system with pedestrian recognition function will start if the owner does not respond. There is also a TSI traffic sign recognition reminder function, which can detect the speed limit sign in real time and present it on the HUD head-up display and the main driving instrument screen, and speeding will warn the driver.

Kykrypton 001 has won numerous awards at home and abroad, and has performed well in China Insurance Research Institute and EU NCAP crash test. The front crash beam is made of aviation grade 7 series aluminum alloy extrusion technology, with an ultra-long energy-absorbing box, which has reached the highest level in China Insurance Research and evaluation, and the energy-absorbing box and ultra-high strength thermoformed longitudinal beam are connected with bolts for easy maintenance.

In a word, Extreme Krypton 001 ensures all-round safety from body and battery to active safety configuration, so that you can travel without worry.

Details of Tank 300 are announced. Off-road is comparable to herdsman, and the fuel tank is as high as 80L.

Haval H9 (parameter picture) and Great Wall cannon are far beyond the expectation of the Great Wall in terms of technical accumulation and user response. Therefore, even though BBA stands out from the crowd with new products at the Beijing Auto Show, WEY brand has finally become a popular brother in its own brand, which shows how powerful the drainage function of the hard-core SUV tank 300 is.

Haval H9 is just a foreshadowing.

According to the expert’s thinking, Tank 300 is actually regarded as the second-generation architecture product in the Great Wall hard-core SUV matrix. The reason for this is not only that WEY tank platform has been able to realize the variable size and parts sharing like Volkswagen MQB and Toyota TNGA on the non-load-bearing body, but also that Great Wall has finally developed a pure hard-core structure part-time 4wd on the harder-core off-road equipment.

We should know that the popularity of Haval H9 and Great Wall Gun on the Internet is nothing more than playing with mud, climbing big slopes and flying sand, which is comparable to Prado’s performance. However, while users marvel that this performance has exceeded the price expectation, users have ravaged this car for a long time, which has also caused the fact that the TOD four-wheel drive (timely four-wheel drive) of Great Wall is still unstable in harsh environment.

Therefore, it is self-evident that Great Wall put the tank platform with part-time 4wd architecture in WEY brand. The first benefit is not only to increase the premium rate of Great Wall in the field of professional four-wheel drive again, but also to help WEY brand open up a second SUV subdivision attribute other than VV series.

Performance herdsman, interior is better than Mercedes-Benz.

With the part-time 4wd system, a trump card related to the life and death of a hard-core SUV, WEY naturally doesn’t need to weigh the balance between space and off-road performance on the tank 300 like H9, so the overall body not only follows the big form of Jeep herdsman, but also continues to improve off-road passing performance through a smaller body and wheelbase.

Of course, in terms of appearance and interior, the tank 300 is also very Nice. The retro shape design with bright colors not only attracts the attention of passers-by, but also moves to the interior full of luxury technology to compete for the attention of minority groups.

Of course, returning to the essence of off-road spirit, the initial product of Tank 300 did not fully use the dreamy 3.0T power configuration in PPT, or the 2.0T+8AT powertrain of Haval H9, but two different sub-models will be launched according to the player’s mentality (capital), that is to say, the road version will still be equipped with the same TOD four-wheel drive system as H9, and the off-road version will be equipped with the latest part-time 4wd system. Who will be after listing?

In this era, apart from a set of reliable four-wheel drive, two locks and three locks, it is absolutely impossible without a dazzling array of electronic auxiliary systems. In addition to having the same tank turning and crawling modes and nine driving modes as H9, Tank 300 has also developed an all-terrain mode similar to Land Rover in 4L mode.

In addition to the help of hardware and electronic control for extreme off-road, the tank 300 is equipped with an 80L fuel tank which is close to the size of the five-door version of herdsman. Therefore, even if the fuel consumption rises to 15L/100km during hard-core off-road, the remaining 70L gasoline is enough to make the tank 300 last more than 450 km.

If we want to predict the price, then this model may once again break through the WEY car price ceiling. Except for the special limited edition, the off-road version will probably come to around 240,000, while the road version will be expected to get started at around 160,000, so it is true that he is a domestic Rubicon.

Have you been tricked into eating sugar, dyeing your hair and playing mobile phones?

  According to the statistics of the Centers for Disease Control and Prevention (CDC), cancer is the second leading cause of death in America. However, when it comes to knowledge about this disease, the public still has a little knowledge about it. To make matters worse, many misunderstandings about diseases spread online and offline, making it difficult for people to identify correct information from unfounded fallacies. American "Best Life" website collects scientific evidence and expert advice, refuting the most common misunderstandings in this field.

  Myth 1: Eating sugar will make cancer worse.

  Perhaps because cancer cells consume more glucose than other cells, people believe that eating sugar will make the disease worse. However, the National Cancer Institute (NCI) refuted this statement, pointing out that "no research shows that eating sugar will make cancer worse, or if you stop eating sugar, the tumor will shrink or disappear."

  Myth 2: The more dairy products you eat,

  The more likely you are to get breast cancer.

  Women can safely eat cheese and yogurt without worrying about breast cancer. The research results published in the International Journal of Epidemiology by researchers from Harvard School of Public Health show that there is no significant correlation between the intake of total dairy products (including both liquid dairy products and solid dairy products) and the risk of breast cancer.

  Myth 3: Eating artificial sweeteners can cause cancer.

  People had this concern in the 1970s and 1980s, because studies at that time showed that the intake of artificial sweeteners (such as saccharin and aspartame) would lead to cancer in mice. However, further tests prove that these substances will not have the same effect on human beings. Nowadays, the US Food and Drug Administration (FDA) claims that all sugar substitutes (except sodium cyclamate) are safe to eat.

  Myth 4: Using mobile phones can cause cancer.

  This common cancer misunderstanding stems from the fact that mobile phones emit electromagnetic radiation. However, there are obvious differences between high-frequency radiation (such as X-ray radiation) and low-frequency radiation (radiation emitted by mobile phones). Although high-frequency radiation will increase the risk of cancer, there is no conclusive evidence that low-frequency radiation has such an effect on the body. Epidemiological studies on the exposure of mobile phones to radio-frequency electromagnetic fields have not shown that users have an increased risk of brain tumors or other cancers.

  Myth 5 Cancer is completely a genetic disease.

  Although medical scientists are still investigating the causes of cancer, the National Cancer Institute of the United States suggests that 5%~10% of cancers are caused by genetic factors, and the remaining risk factors include exposure to harmful substances in the environment (such as tobacco and air pollutants) and genetic mutations caused by aging.

  Myth 6: Only women get breast cancer

  Although it is not common, it is also possible for men to develop breast cancer, but the probability is low. The probability of breast cancer in an average man’s life is 1 in 883.

  Myth 7: If the mammogram results are normal,

  There would be no breast cancer.

  Because mammography may miss important information, it is impossible to make a diagnosis only by mammography. High-risk groups with genetic susceptibility to breast cancer should consider magnetic resonance imaging (MRI) for more accurate screening.

  Myth 8: Hair dyeing will increase the risk of cancer.

  The research results on carcinogenesis of hair dyes are contradictory. Therefore, the International Agency for Research on Cancer (IARC) concluded that hair dyes do not include carcinogens harmful to human beings, but they also warned that occupational exposure (such as hairdressers) may cause cancer to human beings.

  Myth 9: Weight has nothing to do with cancer risk.

  Weight is directly related to the risk of cancer. According to the research results published in The Lancet-Oncology by researchers from the International Agency for Research on Cancer, in 2012, 3.6% of all new cancer cases among adults were related to weight.

  There are many reasons why obese people have a high risk of cancer. One theory is that overweight people have chronic low-grade inflammation, which will damage DNA over time and eventually lead to illness.

  Myth 10: People with dark skin color should not have skin cancer.

  Although skin cancer is more common in people with light skin color, dark skin color does not protect you from ultraviolet radiation. The research results published in the Journal of American Dermatology Association by researchers in case western reserve university, USA, show that melanoma is more deadly to people with darker skin color; Moreover, some skin cancers (such as acral melanoma) are more common in people with dark skin color.

  Myth 11 Using antiperspirants can lead to breast cancer.

  This misconception is that the substances in antiperspirants will penetrate into axillary lymph nodes, causing cell mutation, which will lead to cancer. However, the American Cancer Society refuted this statement, pointing out that "there is little scientific evidence" to support this speculation.

  Researchers at the Fred Haakinson Cancer Research Center in Seattle, USA, published research results in the Journal of the National Cancer Institute, showing that the use of antiperspirants and deodorants has nothing to do with the increased risk of breast cancer.

  Myth 12 Breast augmentation will increase the risk of breast cancer

  A meta-analysis published by FDA researchers in the Journal of Plastic Surgery shows that breast augmentation does not increase the risk of breast cancer. However, it is worth noting that there is a small connection between breast augmentation and anaplastic large cell lymphoma, but this rare cancer can be treated.

  Myth 13: People who receive cancer treatment must be hospitalized.

  Although the treatment of cancer does require several visits to the hospital, patients do not need to stay there until their condition is relieved. In fact, many patients with early cancer can continue to live a normal life and only need to go to the hospital for treatment and examination on a regular basis.

  Myth 14 Only smokers get lung cancer.

  Although smokers are more likely to develop lung cancer, other risk factors (such as secondhand smoke, radon in the air and exposure to asbestos) also increase the risk of lung cancer.

  Misunderstanding 15

  Infection with human papillomavirus will definitely lead to cervical cancer.

  Some strains of human papillomavirus (HPV) develop into cervical cancer over time, but this is not always the case. There are more than 200 strains of HPV, but only a few of them are high risk factors for cervical cancer. About 70% of cervical cancer is caused by two types (HPV16 and HPV18).

  Myth 16

  Negative emotions can make

  The condition of cancer patients is worse.

  Usually, when cancer patients have no improvement after receiving treatment, their instinct is to blame their negative attitude as the root of the problem. However, the American Cancer Society points out that there is no connection between personality characteristics and cancer survival rate.

  Myth 17: Surgery will cause cancer to spread.

  According to the Cancer Council of New South Wales, Australia, there is no evidence to support the spread of cancer caused by surgery. Because this disease grows and reproduces in the blood, it has nothing to do with surgery.

  Myth 18 Herbal supplements can cure cancer.

  According to the research results published in the Journal of Evidence-based Complementary and Alternative Medicine by researchers from Taiwan Province Agricultural Biotechnology Research Center in China, only when combined with conventional treatment can herbal supplements play a role in relieving the disease.

  Myth 19 Biopsy will lead to the spread of cancer.

  Because some patients feel worse after biopsy, they mistakenly believe that exposing cancer to the air will make their condition worse. In fact, there is no evidence that biopsy of lesions will lead to the spread of cancer, and there is no evidence that exposing tumors to the air will lead to its spread to other body parts.

  Myth 20 Chemotherapy always makes patients feel uncomfortable.

  Since the first use of chemotherapy in the 1940s and 1950s, this therapy has made great progress. In order to reduce or even eliminate the side effects, medical scientists have made great efforts, and the patients’ bad feelings are not as serious as imagined.

  Myth 21 Cancer is contagious.

  Cancer itself is not contagious, and you can’t get the disease from others at all. However, some infectious viruses (such as HPV and hepatitis B and C viruses) can cause cancer, so we need to be careful.

  Myth 22 Fluoride can cause cancer.

  Fluoride in tap water and toothpaste does not cause cancer. In February 1991, after reviewing more than 50 population studies, the US Department of Health and Human Services announced that fluoride in its natural form would not pose a cancer risk to human beings.

  Myth 23 getting cancer is equivalent to being sentenced to death.

  Due to technological progress and new medical discoveries, the survival probability of cancer patients is much higher than before. According to the data of the National Cancer Institute, the 5-year survival rate of all types of cancer adds up to about 67%, while for specific cancers such as breast cancer, prostate cancer and thyroid gland, this statistic is as high as 90%.
