There are hundreds of millions of cells in the human body, and cancer cells do exist. The body is metabolizing all the time. If there is cell apoptosis, there will be new cell growth. The dead cells are quickly removed by the immune system and new cells are produced. Studies have shown that the human body can grow more than 10 billion new cells and 1-20 cancer cells every year. During cell division and renewal, DNA replication may be wrong, resulting in gene mutation. Some of the mutated cells are called precancerous cells.
but don’t worry too much. The body has a large cell base, and it’s very normal to make mistakes occasionally. Even if there are cancer cells in the body, it doesn’t mean that you will get cancer. The immune system plays an important role in the body’s internal immune system. The immune system can prevent the invasion of foreign pathogens, repair and repair the mutated cells in the body in time, and it may also directly eliminate the mutation Cell. Generally, the number of cancer cells in the body less than 10 to the fifth power can be suppressed by the powerful immune system. If cancer cells are more than 10 to the power of 6-12, they will exceed the ability of the immune system to clear away, leading to cancer. In other words, whether the immune system is strong or not is directly related to cancer.
but this does not mean that all cancer cells may be inherited to their children, but it is a genetic defect. When there is a gene defect, a little external stimulation will make the cell gene mutation, which has a higher possibility of developing cancer. General colorectal cancer, thyroid cancer, breast cancer, cervical cancer and diffuse gastric cancer have a certain genetic tendency.
chronic diseases will continue to stay in the body, making the body continuously affected and reducing immunity. In particular, patients with atrophic gastritis have a high risk of developing into gastric cancer. Viral hepatitis is likely to increase the risk of liver cancer, intestinal polyps have a certain probability of causing colorectal cancer. Because suffering from chronic diseases can make cells repeatedly damaged and divided, thus reducing immunity, speeding up the number of cell division, prone to carcinogenesis.
People’s living and eating habits can also promote the growth of cancer cells. Some diets in our life have certain carcinogenicity, such as aflatoxin in moldy and deteriorated food, acrylamide in fried food, alcohol and Areca catechu, which are carcinogens, will increase the risk of oral cancer. In addition, a lot of smoking and drinking, always staying up late and bad mood can also promote the growth of cancer cells.
the occurrence of cancer is a long-term and complex process, which often takes decades and multiple stages to complete. As long as you go to the hospital regularly for cancer screening and active treatment, you can prevent the occurrence of cancer. We must stop smoking and drinking, take part in more physical exercises to strengthen our physique, actively control weight, take a low salt diet, eat more fruits and vegetables, cereals and beans, and eat less high calorie food and processed meat. Do a good job in sun protection, to avoid skin exposure to ultraviolet radiation. We can prevent liver cancer and cervical cancer by inoculating hepatitis B vaccine and HPV vaccine. We should go to the hospital regularly for physical examination and choose appropriate cancer screening. CUISINE&HEALTH
