Hello. My age is 25 and for the past few months I have noticed that my left breast have enlarged abnormally. There's a presence of a lump (self examination) but it's painless & doesn't cause any discomfort. I had similar problem a few years ago(2012) and a mammography was done. Two lumps were found, one was in the underarms region and another was in the breast only but there hasn't been a follow up ever since. But now this abnormality in my left breast is really worrying me. Please help!
