The hepatitis virus is very closely related to liver cancer. The risk of cancer is high for people with chronic hepatitis B or hepatitis B carriers. More importantly, women of childbearing age with chronic hepatitis B should be monitored closely throughout pregnancy to avoid hepatitis B virus infection in the newborn and to reduce the risk of liver cancer.
Aflatoxin is another important carcinogenic factor that has strong carcinogenic effects and is found in foods such as moldy corn and peanuts, and can cause liver cancer in people who consume foods containing this toxin for a long time.
Pollution of drinking water is an independent risk factor for liver cancer. The incidence and mortality rate of liver cancer is higher in areas where ditch and pond water are consumed, while the incidence rate is lower when river and well water are consumed.
In addition, alcoholism, liver fluke infection, smoking, and exposure to pesticides are also associated with the development of liver cancer, and the prevalence of liver cancer increases in people living in soil and crops that are deficient in certain trace elements such as selenium and molybdenum.
