Malignant cancer is one of the important causes of human death.Amount of 4290000 new cases of cancer in our country in 2015, and an additional 2.8 million people died of cancer, which is equivalent to about 7,700 people die of cancer every day.With the rapid economic growth, life The change of the way, the destruction of the natural environment, the environmental pollution and the aging of the population, the incidence of malignant tumors shows a trend of significant increase.Gastrogenesis is the result of somatic gene mutation, and many cells in the normal organism every day may be A mutation that does not necessarily lead to a tumor.According to the Cancer Immunoediting doctrine, the immune system’s relation to the tumor can be broken down into three distinct phases, namely “elimination” ,
