The most common liver disease is hepatitis B. There are five processes from virus infection to liver cancer: a. Virus carrier status, that is, liver function and liver ultrasound results are completely normal, which is a healthy carrier and no different from normal people. Second, if the amount of virus is large, it may cause liver inflammation activity, which is called hepatitis active stage 2, and should be treated actively with liver protection and enzyme reduction. Third, if you do not pay attention to or treatment is not complete, not standardized, a long time in the liver is easy to form fibrous tissue under the stimulation of inflammation, the disease will progress to stage 3 that is, liver fibrosis stage. Fourth, many people to the formation of liver fibrosis does not have any symptoms, liver function is also normal, but in the microscopic pathology has been the destruction of inflammation and fibrous tissue proliferation, if this is still not timely treatment, fibrous tissue more and more serious will be separated wrapped around the liver lobules to form a sclerotic nodule, the disease will also enter the fourth stage that is the cirrhosis stage. After cirrhosis, the detoxification and metabolic ability of the liver will be reduced, and malignant changes may occur on the basis of cirrhosis, which is the formation of stage 5 liver cancer. Therefore, if you have hepatitis B carrier, you must have regular checkups in order to detect and treat the problem in time, so that the disease will not develop deeper.
