How to manage seroma post mastectomy?

Eeek, no! Pathology is the place for draining, mercifully no-one even suggested draining mine anywhere else. Apart from anything else there should be a test with the drained fluid to check for infection. Problem with a seroma, especially if it lingers, is that it can become an infection site without any external cause - your own body normally keeps bad bacteria under control, but with external forces such as chemo, your immune system can take a battering. Your body is working overtime to heal, so the fluid is nutrient rich. Great for a wound, terrific for bugs too!
