I'm thinking you need more iodine. Here's why, in the breast are receptors that can accept iodine and also estrogen. If you are low in iodine (totally possible since iodine in bread products was replaced with bromine, which is pro-estrogen) then the receptors bind to any extra estrogens in the body. This can lead to all kinds of breast density, fibrocystic changes and lumps as your boobs don't have what they need.
I don't know if you have kids but I found this great flyer about the importance of iodine during pregnancy. My doc didn't mention anything about iodine to me :/

Then I found this, because we want to know why your body let this foreign body grow inside you -- even if your docs don't care. Why? Because we don't want it to happen again.
Intraductal Papilloma

If your medical team is pretty confident that it is a papilloma, which the bleeding by the nipple means it is up by the nipple, then if I were you I would take a month to take extra iodine and work with someone who knows integrated medicine and see if you can fix you without surgery. You can still opt for surgery if it doesn't work and you will still want to know why this happened and to fix it.
My friend has been taking Lugol's solution to supplement iodine. I have been taking Ionic Iodine from Trace Minerals, 3 drops, plus Concentrace, 10 drops, in a liter of water most days. You might need more than that though for a therapeutic regime in the short-term.
