Introduction: According to the latest data of the World Cancer Report, the number of cancer cases in China in 2012 was as high as 3.05 million, accounting for one-fifth of the global incidence. The number of cancer deaths is as high as 2.2 million, accounting for a quarter of cancer deaths worldwide. This alarming figure has aroused widespread concern and attention to cancer as a malignant disease.
In fact, everyone's body contains carcinogenic factors and proto-oncogenes, and if you are in an unhealthy state for a long time, it is easy to activate these genes and increase the risk of cancer. Therefore, it is very important to prevent cancer and fight cancer, especially in terms of diet, to develop good lifestyle habits and eating habits to reduce the risk of cancer.
There are many significant differences between malignant and benign tumors. First of all, in terms of nature, benign tumors are those that grow slowly, do not spread or metastasize, and are not life-threatening. Malignant tumors, on the other hand, refer to those tumors that grow rapidly, spread and metastasize, and pose a threat to life.
Secondly, from the perspective of tissue structure, the cell morphology of benign tumors is similar to that of normal tissues and is arranged in an orderly manner. On the other hand, the cell morphology of malignant tumors often changes, the arrangement is disordered, and the structure of normal tissues is lost.
Furthermore, from a biological and behavioral point of view, benign tumors can usually be surgically removed** without posing a threat to life. Malignant tumors, on the other hand, are aggressive and metastatic and can spread to other parts of the body** or metastasis, even if they are surgically removed.
In addition, from the perspective of clinical manifestations, benign tumors usually do not cause obvious symptoms, while malignant tumors often cause symptoms such as pain, bleeding, and fever.
Finally, from the point of view, benign tumors can usually be removed by surgery, while malignant tumors need to be carried out by surgery, radiotherapy, chemotherapy and other means, which is more difficult.
First of all, genetic factors are an important influencing factor in the occurrence of cancer. Many studies have shown that cancer runs in families, which means that if there is a cancer patient in the family, the risk of cancer in other members is also increased. In addition, genetics may also affect our susceptibility to carcinogens, making some people more susceptible to cancer.
Secondly, environmental factors are also an important cause of cancer. Long-term exposure to certain carcinogens, such as tobacco, ultraviolet rays, chemicals, etc., can cause cells to mutate, which in turn can lead to cancer. In addition, factors such as eating habits, lack of exercise, etc., may also increase the risk of cancer.
In addition to this, some viral and bacterial infections can also lead to the development of cancer. For example, hepatitis B and C virus infections may increase the risk of liver cancer, and Helicobacter pylori infection may increase the risk of stomach cancer.
1.Green tea: Green tea is rich in tea polyphenols and catechins, which are compounds with strong antioxidant properties and are able to fight free radical damage to cells, thereby preventing gene mutations and inhibiting the growth of cancer cells.
2.Tomatoes: Tomatoes are rich in lycopene, an antioxidant that scavenges free radicals in the body and protects cells from damage, thereby preventing the occurrence of cancer.
3.Nuts: Nuts are rich in vitamin E and minerals, which enhance the function of the immune system and improve the body's resistance to cancer cells.
4.Deep-sea fish: Deep-sea fish are rich in omega-3 fatty acids, which can reduce inflammation and reduce free radical damage to cells, thereby preventing the occurrence of cancer.
5.Vegetables and fruits: Vegetables and fruits are rich in vitamins, minerals, and antioxidants, which are able to strengthen the function of the immune system and improve the body's resistance to cancer cells.
