question: I had a lump above my left nipple that now has blood and puss coming out of it. should this be something i should be worried about. The lump has been there for a few months and when i went to the dr she sent me for an ultrasound and they said they did not believe it was cancerous but never did any other test to see what it was. So then there was a pimple like bump on there that burst there was a lot of blood and for the past couple of days it has been more puss mixed with blood.
