How long primary liver cancer can live depends on the stage of liver cancer, the treatment measures taken, the patient’s physical condition and so on, which requires specific analysis and cannot be generalized. Primary liver cancer is one of the common tumors in China, with more men than women. Surgery is the first choice of treatment for most primary hepatocellular carcinoma. For example, if patients with early stage hepatocellular carcinoma can undergo radical hepatectomy or radiofrequency ablation treatment, their 5-year survival rate can reach 60%-70%. In addition to surgery, radiotherapy, chemotherapy and targeted therapy can be combined, and individualized treatment according to different stages of liver cancer is the key to improve the curative effect. Generally, the survival period of early to mid-stage primary liver cancer patients can reach 3-5 years through reasonable and effective treatment. However, for patients with end-stage liver cancer, their survival period is usually shorter, which may be only six months or even three months. After being diagnosed with primary liver cancer, patients need to pay extra attention to their diet, which should be low-fat, high-calorie and high-vitamin diet, ensure protein intake, avoid spicy, alcoholic and moldy food, etc.
