Good advice above on needles and arms.
I had the most irritatingly persistent, large seroma right through chemo. My oncologist deferred starting chemo for a week or so, but then went ahead. Drained and cheerfully refilled several times. As far as I am aware, the chemo didn't affect it in any way (good or bad) but the repeated build up of nice warm fluid in the body is a perfect environment for the bad bacteria we all have in our bodies to have a field day. I got two minor infections (flu like symptoms) both of which cleared up quickly, but then nearly 5 months after chemo was finished, got a really bad infection. The only good part was that in order to clear out all the infection, the surgery fixed the seroma once and for all : ). So good if you can get rid of it soon. Best wishes for tomorrow.
