Many late stage cancers will have ascites, and some relatively small amount of ascites may be caused by hypoproteinemia. Human albumin can be infused to correct hypoproteinemia, which can also promote ascites absorption. In addition, some diuretic and drainage drugs can be applied, which also help to metabolize ascites, while paying attention to oral intake to increase nutrition. There are many types of cancer, and some types of cancer, such as liver cancer, may have ascites even if they are not very advanced. Like cirrhosis can also lead to ascites. If it is related to liver dysfunction and other causes, you can apply liver-protective and nutritional support drugs that can also improve ascites, and you can also apply abdominal puncture and fluid extraction to drain ascites. Then do peritoneal perfusion chemotherapy to control ascites.
