I am 58 and had a total masectomy and removal of sentenal node almost three months ago. The drainage tube was removed three weeks after surgery. Since then I have still had a build up of fluid which has been removed through a needle every week to two weeks. I am an active person. Is it possible that I am causing this persistant seroma to exist through excess activity or overusing my left arm--site of the surgery? My surgeon initially discussed injecting an antibiotic into my chest which will roughen up the surfaces causing them to adhere and heal. She said that the injection is extremely painful. This week more fluid had accumulated (50 ml in 8 days), and she now suggests another surgery, one that burns the surfaces to cause them to stick together. Obviously, I don't want to have another surgery, have the drainage tube again, and go through recovery. I am also concerned that the seroma may come back again after the second surgery. Is it common for a seroma to last for over three months? Do they eventually heal if left alone, or is surgery or other methods sometimes necessary? Are these treatments successful? Thanks!
