Incision still seeping after 10 weeks

I'm new to this forum but I have to ask some questions and maybe someone else has gone through this.  I was diagnosed on March 11 with DCIS, had a lumpectomy on April 8.  Initially, no problems at all.  After the drainage tube was removed (a week later), my breast became very swollen and hard.  Went to the ER and they gave me antibiotics although didn't see any evidence of infection.  The next day, a part of the incision busted open and began to drain (a lot).  I went to my GP and he said to keep it clean but allow it to drain.  Well, it drained for a long time and was not healing.  I went back and the doctor had to manually squeeze the breast, saying that I had a hematoma.  The drainage was thick (like jelly) but again, he assured me it would heal over time.  Well, last week it finally closed over (10 weeks later).  I had my appointment with Oncology and had a simulation for my radiation treatments (4 weeks of treatments).  The treatments will likely begin in the next two weeks but today my incision is once again seeping!  It isn't a lot, but there is a yellow discharge.  The breast isn't red and I don't think it is infection but it really has to stop.  Does anyone have any suggestions?  I have been showering regularly--maybe I should keep it dry?  I'm tired of having to put a small dressing in my bra every day.  I'm anxious to get the radiation started and I'm hoping this won't delay things.
