Cancer is unpredictable in many cases. Studies have shown that about 2/3 of cancer cases are due to your “bad luck”, that is to say, your cells are divided by a random error in DNA replication, which leads to the development of cancer cells. However, the remaining 1/3 of cancers are still under our control, and these cancers are closely related to our living habits, such as colorectal cancer and cervical cancer. Of course, these habits can not only reduce the incidence of cancer, but also reduce the incidence of other diseases at the same time, so that you can exist in this world for a longer time. 1. Regular testing for some particular types of cancer. The earlier they are detected, the easier they are to treat, which means more certainty of controlling the cancer! Colorectal microscopy, cervical smear, these routine tests should be tested regularly for older people. As children than all kinds of health care products, taking mom and dad for a medical checkup is better than anything! 2, maintain the body shape. Excess weight and obesity have been proven to be positively associated with a variety of cancers, including breast cancer, colon cancer, endometrial cancer, kidney cancer, esophageal cancer and pancreatic cancer, and we can completely achieve the purpose of weight control through exercise and diet. 3. Maintain the habit of exercise. Physical activity can reduce the incidence of breast cancer and prostate cancer. It can also reduce the incidence of diabetes and heart disease, “exercise” is a panacea, this is true. It is generally recommended that adults should have 150 minutes of moderate exercise per week, or 75 minutes of vigorous exercise (sweating, increased heart rate), and children should have one hour of exercise per day. 4, a healthy diet. Intake of a variety of rich fruits and vegetables can reduce the incidence of some specific cancers. The American Cancer Society recommends: reducing the intake of red meat, reducing the intake of sugar, and a certain amount of vegetables and fruits should be consumed every day. 5. Avoid tobacco and alcohol. Tobacco and lung cancer have a strong correlation, tobacco causes about 480,000 deaths per year in the United States, causing 80% of lung cancer, 30% of other cancers caused by tobacco, recommendations: if you do not smoke, do not get involved, if you are smoking, please quit smoking as soon as possible. And alcohol is said to be associated with liver cancer, oral cancer, laryngeal cancer, esophageal cancer.
