How long a patient can survive after hepatocellular carcinoma develops ascites is related to the patient’s physical quality, the speed of disease development, treatment and other factors, and cannot be generalized. Ascites is one of the late complications of liver cancer, when the patient’s health quality decreases. With more and more ascites, patients may have symptoms such as abdominal distension, anorexia, vomiting, difficulty in breathing, swelling of lower limbs, etc. In serious cases, drowsiness and coma may also occur, which means complications such as liver failure and hepatic encephalopathy, etc. At this time, patients’ prognosis is poor and the death rate is high. Moreover, the ascites of liver cancer patients keeps increasing, most of them are cancerous ascites, which marks the spread of cancer cells. Therefore, patients with liver cancer may only survive for about 1-5 months after they have a large amount of ascites, so it mainly depends on the patient’s own condition. Patients with liver cancer should face the treatment and various outcomes with a positive attitude, actively carry out treatment after the appearance of ascites and not give up, and family members should actively guide patients, eat reasonably and improve the quality of life.
