Recently, the American Cancer Society's official journal published the 2018 global cancer statistics report, which evaluated 36 cancer incidence rate and mortality rates in 185 countries.
There are several data worth noting:
1. In 2018, there were about 18.1 million new cancer cases and 9.6 million cancer deaths worldwide.
2. Asia accounts for nearly half of the 18.1 million new cancer cases, and nearly 70% of the 9.6 million cancer deaths.
3. lung cancer is still the first malignant tumor with incidence rate (11.6%) and death rate (18.4%). Incidence rate was followed by female breast cancer (11.6%), prostate cancer (7.1%), colorectal cancer (6.1%), followed by colorectal cancer (9.2%), gastric cancer (8.2%), and liver cancer (8.2%).
4. After cancer, the death rate of men is much higher than that of women! Among the 18.1 million new cancer cases, 9.5 million are men, nearly half of which are Asian men; the death rate is 60%. There were 8 million 600 thousand new cancer patients in the female population, with an incidence rate of 47.5% in Asian women and half in death rate.
5. China's cancer incidence rate and mortality rate is the highest in the world, 18 million of the new cancer cases and 9 million 600 thousand of cancer deaths, 3 million 804 thousand cases of new cases and 2 million 296 thousand cases of death cases. Compared with other countries, China's incidence rate and mortality rate is the highest in the world.
This group of data also means that for every 100 new cancer patients in the world, 21 are Chinese. That is to say, there are more than 10000 people diagnosed with cancer every day in China, with an average of 7 people getting cancer every minute. On average, more than 6000 people die of cancer every day, and nearly five die of cancer every minute.
Lung cancer is also the highest incidence rate in China. But compared with the world, colorectal cancer, liver cancer, esophageal cancer, gastric cancer and other digestive system cancers still account for a large proportion.
Ten carcinogens you can avoid
Some people always ask, why do you get cancer? What causes cancer? We must admit that cancer is the result of multiple factors. The related factors of cancer occurrence mainly include two aspects: one is external factors, that is, external environmental factors; the other is internal factors, that is, individual factors.
One of the factors: environmental pollution
Including air pollution, water pollution, soil pollution, etc., which is one of the most important causes of cancer.
Two factors two: smoking and drinking
There is a general consensus that smoking increases the risk of multiple cancers (including lung cancer, oral cancer, laryngeal cancer, esophageal cancer, bladder cancer, etc.). Alcoholism also increases the risk of cancer, which is mainly related to the occurrence of gastrointestinal cancer. The risk of cancer in alcoholics is higher than that in non alcoholics. Smoking and drinking, wrong plus wrong, the risk is not just a superposition, but one plus one more than two.
Three factors: radiation exposure
The so-called radiation exposure mainly includes ionizing radiation and ultraviolet radiation, which are all physical carcinogenic factors. Specifically, it is electromagnetic radiation such as X-ray and gamma ray, particle radiation generated by radioactive particles such as proton, a particle and heavy particle, and ultraviolet radiation of sunlight. Long term exposure to nature, medicine and life of various sources of ionizing radiation, cancer can occur.
Four factors four: virus infection
The infection of some bacteria and viruses is also related to the occurrence of cancer. For example, the infection of hepatitis B and C is related to primary liver cell carcinoma, the infection of human papillomavirus is related to cervical cancer, anal cancer and oropharyngeal cancer, the infection of EB virus is related to NPC and some lymphoma, the infection of Helicobacter pylori is related to gastric cancer and gastric lymphoma.
5 factors 5: lack of exercise
Sedentary, less exercise, this is the common fault of modern people, not exercise or very little exercise. Sedentary and unrestricted diet lead to the accumulation of excess fat in the body, resulting in overweight and obesity, which increases the risk of breast cancer, endometrial cancer, ovarian cancer, colon cancer, etc.
Six factors: improper diet
It mainly includes two aspects: one is that the diet structure is unreasonable, the fruits and vegetables are eaten less, and the meat, especially the processed meat, is eaten more; either the nutrition is insufficient, or the nutrition is excessive; the other is that the poor diet habits, such as overeating, eating irregularly, like eating salted, roasted and fried food.
7 factors 7: lifestyle
The occurrence of many cancers also has a certain relationship with poor lifestyle, in addition to the aforementioned smoking, drinking, lack of exercise and sedentary, poor eating habits, obesity or overweight, as well as staying up late.
Eight factors: psychological factors
At present, the relationship between cancer occurrence and psychological factors is not clear, but long-term mental depression is in a negative mood, which may indeed bring a series of health problems, such as poor sleep, affect appetite, weaken the body's immunity, and may indirectly increase the risk of cancer.
Nine factors nine: drug abuse
Drug is a double-edged sword, always has two sides, while bringing curative effect, there must be some side effects, rare drugs with a single effect. The improper abuse of some drugs may turn the therapeutic drug into a carcinogen, especially for a long time.
Ten of 10 factors: genetic factors
Some cancers do have genetic predisposition, such as breast cancer and colorectal cancer. However, it must be noted that cancer is not directly inherited, it is only the inheritance of cancer susceptibility. In recent years, there have been so-called "random luck factors", but in any case, we should focus more on controllable and preventable factors. Finally, cancer is the result of multiple factors, which is almost the consensus of all oncologists. If you can avoid a few more of the top ten carcinogens, then your risk of cancer will be greatly reduced compared with other people!
