If the tumor grows on the surface of the body, it usually does not produce ascites, but if it is a benign tumor that grows in the abdominal cavity, such as ovarian follicular tumors, it may produce ascites, which may disappear on its own after removing the primary tumor. There are many reasons for ascites, if you find ascites, you should consult doctor to find out the cause, if it is caused by benign tumor, you need to control the growth of the tumor, and strive for radical surgical resection, and after surgery, you should have regular review, pay attention to the changes of the condition, and deal with it in time.
