Liver cancer can be detected in early stage. Liver cancer has a family history, and if an immediate family member has liver cancer, the possibility of children getting liver cancer will be significantly increased. It is necessary to have regular medical checkups at the hospital, and it is better to have annual liver ultrasound. If the ultrasound reveals an occupancy in the liver, that is, if a mass is found and liver cancer is suspected, further liver enhancement CT is needed for further clarification. Most liver cancers can be detected by enhanced CT, which has a fast-in and fast-out feature under CT. If a patient has hepatitis B, the disease may also progress to liver cancer when it progresses to a certain time. When there are uncomfortable symptoms in the right upper abdomen, such as vague pain and distension, it is important to go to hospital for examination in time. If liver cancer can be diagnosed at an early stage and treated early, it is very effective to perform radical tumor surgery.
