It is an indisputable fact that cancer is highly prevalent due to factors such as environmental pollution, bad living habits and heredity, etc. The 2012 China Tumor Registry Annual Report released in January 2013 shows that nearly 6 people are diagnosed with cancer every minute. Early detection and early treatment are the best means to fight against cancer, but it is necessary for us to know in advance which kind of people cancer cells like to find the most. Lung cancer: people who smoke heavily for a long time; people who are exposed to grease fumes for a long time Smoking is the main culprit that induces lung cancer. Statistics show that 9 out of 10 patients who die of lung cancer are smokers. 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. Suggestions: Smokers should quit smoking, and smoking should be banned in all public places; people over 45 years old who have a history of smoking should have a cancer checkup once a year. In order to reduce the harm of kitchen fumes, less high temperature frying food should be done, and middle-aged and elderly women who have been engaged in cooking for more than 30 years should pay attention to regular medical checkups. Stomach cancer: people with stomach ulcers who still love to eat leftovers; people who abuse alcohol; people who love to eat pickled food People with stomach ulcers and other chronic gastric diseases have a higher chance of getting stomach cancer than other people. If people who already have these diseases always eat leftovers, the potential bacteria in them may induce stomach cancer. Alcoholics should also be on the alert, as alcohol can do comprehensive damage to the body. Suggestions: Eat more green and yellow vegetables; eat less salty, pickled, dry, hard and moldy food; limit alcohol; men over 40 years old, with a family history of stomach cancer, history of chronic gastric disease and infected with Helicobacter pylori should have regular checkups. Esophageal cancer: people who love to eat hot food; people who eat too fast Eating too fast, too hot or drinking alcohol for a long time may repeatedly burn or damage the mucosa of esophagus, making it in a state of repair for a long period of time, which will produce cancer. Some statistics show that more than 90% of esophageal cancer patients prefer hot food and hot drinks. Suggestions: People who have esophageal cancer patients in their immediate family should have regular medical checkups; usually try to avoid eating too fast and too coarse, and the temperature of food should be below 40 degrees Celsius. Liver cancer: people who are addicted to alcohol; people with underlying liver disease Drinking alcohol is most damaging to the liver. Long-term heavy drinking will cause repeated damage to liver cells, leading to cirrhosis, and the proportion of cirrhosis transformed into liver cancer is as high as 70%. There are two other important causative factors for liver cancer, namely viral hepatitis and aflatoxin, the latter of which is mostly found in moldy foods. Suggestions: vaccination against hepatitis, people with hepatitis should pay special attention to limiting alcohol, and develop healthy eating habits, such as not eating moldy food. Bowel cancer: people who eat too much meat; sedentary people Bowel cancer has a similar genetic pathogenesis as diabetes and hypertension. Reflected in the lifestyle, mainly eating too much meat all year round, lack of dietary fiber intake; sedentary less mobile, not on time defecation. Obese people are more likely to be hit. Suggestions: eat less and move more. Eat less fried, fried, pickled food, eat red meat every week no more than 1 pound; moderate increase in exercise, and develop the habit of regular bowel movements. Breast cancer: people over 40 years old who are not pregnant or 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 are late marriage and late childbearing, frequent consumption of contraceptive pills, heavy exposure to chemicals with estrogen-like effects (such as cosmetics, etc.), and high mental stress. Suggestions: women should eat more vegetarian food; it is best to breastfeed until the child is 6 months old; women with a family history of breast cancer, over 40 years old and not pregnant, overweight women should do a physical examination and early breast cancer screening once a year.
