Background art
- Cancer has been the leading cause of death in Japan since 1981, despite remarkable advances in medical technology. Therefore, public interest is shifting to cancer prevention. Therefore, it is necessary to know the development process first and to prevent cancer.
- carcinogens are taken into the body, metabolized by the body's protective abilities, and excreted outside the body. Part of the body that accumulates in the body goes through three stages and eventually leads to the disease of cancer. First, these carcinogens damage cellular genes in a short period of time (eg, several days), resulting in displaced cells. These displaced cells become precancerous cells after a latent period of several to several decades. Finally, precancerous cells proliferate at a rapid rate (for example, one year) and become cancerous. Until these pre-cancerous cells become us, we do not feel anything and it is difficult to detect them with modern medical technology, so if cancer is diagnosed, it is said that life expectancy is short. That is.
