Hepatitis B and C are both negative may also get liver cancer. There are many causes and pathogenesis of liver cancer, including not only hepatitis B and C virus infection, but also long-term consumption of aflatoxin-contaminated food, long-term exposure to nitrosamines, phenol and other chemical substances, smoking, alcoholic liver disease and so on. The above factors cause liver cells to be constantly damaged and repaired, allowing their biological characteristics to gradually change, which ultimately leads to the development of liver cancer. Therefore, the negative results of hepatitis B and C tests do not mean that you will not develop liver cancer. You can actively prevent liver cancer from occurring by eating fresh and clean food, quitting smoking, not abusing alcohol, avoiding staying up all night, and avoiding exposure to radioactive cancer-causing chemicals, etc. If you have long-term smoking, cirrhosis, or other diseases, you may not be able to develop liver cancer. If patients have high risk factors such as long-term smoking and cirrhosis, they should actively go to the hospital for follow-up and treatment according to the doctor’s advice, so as to detect liver lesions and treat them as early as possible.
