Do ya'll do them? I do every once in a while, in the shower, while I'm lathered up.About a month ago, I found a lump on my left breast, where my chest and breast meet . Kinda angled toward my armpit. It is still there, no bigger but no smaller. It's about 1 1/2-2 inches long. It doesn't hurt or anything. Do ya'll think this sounds like something that needs to be checked. I've been passing it off as my hormones being out of wack and causing it. But since it's still there over a month, I don't know.... Help.
