The high incidence of cancer has become an indisputable fact due to factors such as environmental pollution, poor living habits and genetics. 2012 China Tumor Registry Annual Report released in January 2013 shows that there are about 3.12 million new tumor cases in China every year, with an average of about 8,550 people struck every day and nearly 6 people diagnosed with cancer every minute. Yuan Fenglan, professor of cancer prevention department of Cancer Hospital of Chinese Academy of Medical Sciences, said that early detection and early treatment are the best means to fight against cancer, but it is necessary for us to know in advance what kind of people cancer cells like to find most. Lung cancer: people who smoke a lot for a long time; people who are exposed to oil smoke for a long time Smoking is the main culprit to induce lung cancer. Statistics show that 9 out of 10 patients who die of lung cancer are smokers. Yuan Fenglan pointed out that smoking more than 20 cigarettes a day for more than 20 years is most likely to induce lung cancer. People who are often forced to inhale second-hand smoke also have a relatively high chance of developing cancer. A study by the Institute of Oncology of Tongji University in Shanghai found that long-term exposure of young and middle-aged women to high-temperature oil smoke increases their risk of lung cancer by 2 to 3 times. Another five-year survey in Shanghai showed that people who often eat fried or deep-fried food on the roadside have three times the risk of lung cancer than others. Suggestions: Smokers should quit smoking and ban smoking in public places, and people over 45 years old with a history of smoking should have an annual cancer checkup. Zhi Xiuyi, director of the Lung Cancer Treatment Center of the Capital Medical University, said that in order to reduce the damage of kitchen fumes, it is necessary to do less high-temperature fried food, and middle-aged and older women who have been engaged in cooking for more than 30 years should pay attention to regular medical checkups. Stomach cancer: people who have stomach ulcers and still love to eat leftovers; alcoholics; people who love to eat pickled food People with chronic stomach diseases such as stomach ulcers have a higher chance of getting stomach cancer than others. If people who have these diseases eat leftovers, the potential bacteria in them may trigger stomach cancer. Alcoholics should also be alert to the fact that alcohol can harm the body in a comprehensive way. Professor Shen Lin of Beijing Cancer Hospital said that people who like to eat high-salt diet and pickled food, especially unpickled food, have relatively higher rate of stomach cancer. Suggestions: eat more green and yellow vegetables; eat less salty, pickled, dry and hard, moldy food; limit alcohol; men over 40 years old, those with family history of gastric cancer, history of chronic gastric disease and infected with Helicobacter pylori should have regular checkups. Esophageal cancer: people who love to eat hot; people who eat too fast Long-term eating too fast, too hot or drinking alcohol may repeatedly burn or damage the esophageal mucosa, leaving it in a state of repair for a long time, thus producing cancer. Statistics show that among esophageal cancer patients, those who usually prefer hot food and hot drinks account for more than 90%. Suggestions: People who have esophageal cancer patients in their immediate family should have regular medical checkups; try to avoid eating too fast and too coarse in general, and the temperature of food should be better below 40 degrees Celsius. Liver cancer: people who are addicted to alcohol; people with underlying liver disease Drinking alcohol is the most damaging to the liver. Long-term heavy drinking will cause repeated damage to liver cells, leading to cirrhosis, and the rate of conversion from cirrhosis to liver cancer is as high as 70%. Liver cancer also has two important causative factors, namely viral hepatitis and aflatoxin, the latter mostly found in moldy food. Suggestions: get vaccinated against hepatitis, pay special attention to limiting alcohol for those who have hepatitis, and develop healthy eating habits, such as not eating moldy food, etc. Bowel cancer: people who eat too much meat; people who are sedentary Bowel cancer has a similar genetic pathogenesis as diabetes and hypertension. Reflecting on the lifestyle, it is mainly due to excessive meat eating and lack of dietary fiber intake; sedentary people who do not move much and do not have bowel movement on time. Obese people are more likely to be affected. Suggestions: eat less and move more. Eat less fried, pan-fried and preserved foods, and eat no more than 1 pound of red meat per week; increase the amount of exercise and develop the habit of regular bowel movement. Breast cancer: people over 40 who are not pregnant and not breastfeeding; people who often take birth control pills Among the high incidence of cancer in women, breast cancer has surpassed lung cancer to become the first. The main causes of breast cancer include late marriage and late childbirth, frequent use of birth control pills, heavy exposure to chemicals with estrogen-like effects (such as cosmetics), and mental stress. Suggestions: women should eat more vegetarian food; it is better to breastfeed until the child is 6 months old; women with family history of breast cancer, not pregnant over 40 years old, and overweight should have a physical examination and early breast cancer screening once a year. Thyroid cancer: people who receive too much radiation; people who consume too much iodine The causative factors of thyroid cancer are unknown, but the thyroid gland is sensitive to the radiation environment, such as radiation during medical examinations, radiation from nature, etc. In addition, excessive iodine intake can also have an effect. Suggestions: Be aware of protection and minimize exposure to items with high radiation; women, those with family history of thyroid cancer, residents of coastal areas and other groups with high incidence of thyroid cancer should have at least one medical checkup per year. Cervical cancer: people with chaotic sex life China currently has 100,000 new cases of cervical cancer every year, accounting for 1/5 of the global cases. human papilloma virus infection is its biggest cause. In terms of lifestyle, people who start their sexual life too early, multiple sexual partners and other people with chaotic sexual life are among the high risk groups. Recommendation: The most effective way to prevent cervical cancer is to get vaccinated against cervical cancer, and those with chronic cervical disease should be treated actively. The most effective way to prevent cervical cancer is vaccination and active treatment of chronic cervical disease.
