The latest cancer statistics report is released： lung cancer has once again become the largest cancer in the world.
April 15th to 21st is the 30th National Cancer Prevention Publicity Week. The theme of this week is "Comprehensive Policy and Scientific Cancer Prevention", which advocates everyone to be the first responsible person for their own health. According to the report released by the National Cancer Center, in 2022, it is estimated that there will be 4.825 million new cancer cases and 2.574 million new cancer deaths in China. Among the new cases, the top five cancer types are lung cancer, breast cancer, colorectal cancer, thyroid cancer and liver cancer.
the whole world
Lung cancer has become the largest cancer killer in the world, followed by breast cancer and colorectal cancer.
IARC)Freddie, the International Agency for Research on Cancer (IARC) under the World Health Organization.
The team led by Bray recently published the latest cancer report in authoritative journals in the medical field. According to IARC data, in 2022, it is estimated that there will be 19.974 million new cancer cases and 9.744 million cancer deaths worldwide. Among them, the number of new cases of lung cancer reached 2.481 million, accounting for 12.4% of the new cases of cancer in the world. This is also the first time that lung cancer has become the largest cancer in the world after being surpassed by breast cancer in 2020.
At the same time, lung cancer is also the largest cancer killer in the world. In 2022, it caused 1.817 million deaths, accounting for 18.7% of all cancer deaths, followed by breast cancer, colorectal cancer, prostate cancer and gastric cancer.
According to the assessment of FreddieBray’s team, about one-fifth of people in the world will get cancer in their lifetime, and about one-ninth of men and one-twelfth of women will die of cancer. However, due to the difference of development level, the cancer detection rate and cancer survival rate may be significantly different among different countries. Take breast cancer as an example. In areas with very high human development index, one in every 12 women will be diagnosed with breast cancer, and one in every 71 will die of breast cancer. However, in areas with low human development index, although only one in every 27 women will find that they have breast cancer, one in every 48 women will eventually die of breast cancer.
China
The incidence of female lung cancer in China is 2.6 times of the global average.
In the cancer data released by the International Agency for Research on Cancer, the situation in China was jointly calculated by the Agency and the National Cancer Center (NCC) in China. The National Cancer Center has also published a number of studies, such as "Analysis on the Epidemic Situation of Malignant Tumors in China in 2022", which introduced the latest cases of malignant tumors in China in detail.
In 2022, it is estimated that there will be 4.825 million new cancer cases and 2.574 million new cancer deaths in China. The first cancer in China is lung cancer. Only compared with the whole world, the disease burden of lung cancer in China is more prominent. Throughout 2022, the number of new lung cancer patients in China reached 1.061 million, equivalent to 75.1 per 100,000 people suffering from lung cancer.
At the same time, lung cancer is also the most "fatal" cancer in China. In 2022, 51.9 out of every 100,000 people will die of lung cancer. This is related to the fact that lung cancer usually has no symptoms in the early stage. Once found, it may have developed to the advanced stage. Moreover, the prognosis of lung cancer is poor. Research shows that the five-year survival rate of lung cancer patients in China is only 19.7% from 2012 to 2015.
However, the incidence and mortality of lung cancer in women are significantly lower than those in men.
Thyroid cancer and breast cancer are common health problems of women in China, both of which are related to estrogen level. It is found that there is an increasing risk between these two cancers. Compared with the general population, patients with either of these two cancers are more likely to develop the other cancer.
Fortunately, the mortality rates of breast cancer and thyroid cancer are not very high-in 2022, for every 100,000 women in China, the number of deaths from breast cancer and thyroid cancer was 10.9 and 1.1 respectively. As early as 2010 to 2014, the five-year survival rate of breast cancer patients in China has reached 83.2%.
Among the top ten high-incidence cancers in China, the incidence and mortality of other cancers are higher than the global level except those in reproductive organs.
What is striking is that the incidence of lung cancer among women in China is 2.6 times that of women in the world, while the smoking rate among women in China is only 1.85%, which is lower than many countries in the world. It is speculated that the high incidence of lung cancer in women is partly due to the air pollution in the outdoor environment and the indoor air pollution caused by the burning of solid fuel during home heating and cooking.
remove doubts
Is it an illusion that more and more people are suffering from cancer?
Compared with the incidence announced in previous years, the incidence of some cancers among China residents in 2022 increased a lot. For example, the crude incidence of thyroid cancer was 13.9 per 100,000 people in 2017, and by 2022, this figure soared to 33.0.
In this regard, the National Cancer Center reminded in a study that the detection rate of cancer is indeed rising due to the improvement of people’s awareness of cancer prevention and the increase of people who take the initiative to seek medical treatment. However, a statistical factor that can’t be ignored is that the cancer data of China released by IARC before came from the situation of some cancer registries in China, instead of being calculated based on the data of 2,806 existing cancer registries in China in 2022. Therefore, the gap between IARC’s cancer data in China IARC2022 and before does not accurately reflect the changes of cancer in China.
Is the incidence of cancer among China residents on the rise? Based on the continuous follow-up data of 22 cancer registries in China, some researchers analyzed the changes of incidence and mortality of different cancers in China from 2000 to 2018, thus eliminating the influence of changes in data sources.
Their conclusion is that in recent 20 years, the incidence of cancer in China is increasing and the mortality rate is decreasing. In terms of gender, the incidence rate of women is increasing significantly, while that of men is in a stable trend.
In 2022, the new cases of thyroid cancer in China accounted for more than half of the new cases of thyroid cancer in the world, which is also a significant increase of cancer for both men and women in China, with an annual increase of 16.9% and 15.7% respectively from 2000 to 2018.
However, thyroid cancer is not terrible. It is an inert asymptomatic tumor. The rapid rise of thyroid cancer in recent years is mainly related to the improvement of people’s awareness of cancer prevention, better medical care opportunities and the popularization of detection technology.
In China, the incidence and mortality of liver cancer, gastric cancer and esophageal cancer, which have high incidence and poor prognosis, are declining continuously. At the same time, some cancers, such as colorectal cancer, prostate cancer in men and breast cancer in women, which used to be low in China and high in developed countries, are on the rise.

How to reduce the risk of cancer in daily life?
How to reduce the risk of cancer in daily life? Listen to the advice of experts.
■ Change the unhealthy lifestyle
Smoking, alcoholism, obesity, stress, lack of exercise and unreasonable eating habits are all risk factors for cancer. Smoking cessation and alcohol restriction, balanced diet, moderate exercise and keeping a good mood can effectively reduce the occurrence of cancer.
■ Pay close attention to carcinogenic factors.
Cancer is not contagious, but some bacteria (such as Helicobacter pylori) and viruses (such as human papillomavirus, hepatitis virus, EB virus, etc.) closely related to cancer are contagious. Maintaining personal hygiene and a healthy lifestyle can prevent cancer.
■ Stay away from carcinogens around you.
There are many definite carcinogens around us, such as formaldehyde, aflatoxin and nitrite. It is recommended not to eat moldy food, and to eat less fried and pickled food.
■ Vaccination to prevent some cancers
HPV vaccine can prevent cervical cancer, oropharyngeal cancer, anal cancer, penile cancer and other cancers. Hepatitis B vaccine can prevent hepatitis B virus infection, and hepatitis B is a high risk factor for liver cancer. Vaccination can avoid infection with related bacteria and viruses, so it is recommended to vaccinate as soon as possible.
■ Stay optimistic.
A good attitude is a good medicine to prevent and fight cancer, and a positive attitude can help us maintain a normal and reasonable life. Learn to be optimistic and cheer up. Good at self-comfort, self-liberation. Avoid impatience, anger or unhappiness.
■ Choose individualized anti-cancer physical examination
Tertiary prevention can effectively reduce the incidence and mortality of cancer. At present, most common cancers can be found early by technical means. For example, low-dose spiral CT can be used to screen lung cancer, ultrasound combined with molybdenum target can screen breast cancer, and gastrointestinal endoscopy can screen digestive tract cancer.
Choosing individual physical examination items according to individual genetic history, disease history, age and previous examination results is the key to improve the early diagnosis rate of cancer.
■ Be alert to early symptoms
The earlier cancer is found, the better the treatment effect and the longer the survival time. When the body has symptoms such as abnormal lump, persistent pain, blood in sputum, painless hematuria, changes in stool habits and characteristics or blood, you should go to the hospital in time.
