So, if the 20-30 year old often contact carcinogens, the result will be 40-50 years after the onset of disease, so that the age of cancer seems to be big.

With age, the immune function of the body is weakened, so the immune surveillance effect of the disease gradually decreases since the age of 40. The decrease of immune function is beneficial to the occurrence and development of tumor.

The greater the age, the more chance of exposure to cancer causing factors, and the carcinogenic factors on the body will also be more and more big, such as smokers, smoking longer, the possibility of cancer will increase.
