As everyone knows, one of the diseases that threatens human life is cancer. Annually, there are about 1.5 million people dying of cancers, and the number is increasing. With the changes of the way of life and social environment, the incidence of cancers has been rising in recent years, and more and more young people are likely to develop cancer, such as mammary and colorectal cancers.
