Decreased ascites in patients with hepatic malignancy may be due to better treatment and corrected albumin levels in the body. The main reasons for ascites in patients with liver malignant tumor are: 1. Tumor proliferation Tumor cells spread to the peritoneum, destroying the permeability of the peritoneum, thus ascites appears. If ascites is caused by tumor cells spreading to peritoneum, after appropriate treatment, ascites becomes less, which generally indicates that the treatment plays a certain effect. 2. Impaired liver function Impaired liver function reduces albumin synthesis, resulting in hypoproteinemia and ascites. If the ascites is caused by hypoproteinemia, it may be caused by eating some high protein food frequently in the diet, increasing the protein intake, or transfusion of albumin, thus correcting the albumin level in the body, and making the ascites become less. Patients with hepatic malignant tumors whose ascites becomes less should consult with their treating doctor in time to choose the next step of treatment according to the specific situation and control the condition as much as possible.
