Lots of Lumps in Life

I've had a surgeon following a lump in my breast that I found at the beginning of the year. We don't really think it is much of a threat, but it is larger than my run-of-the-mill fibrocystic lumps. I'm a little OCD with the thing (should I name it?) because I see worst case scenarios all the time, and he is a little OCD with the thing (names, anyone?) because he's an expert on breast health. So we're contemplating a lumpectomy because the mass is so close to the surface of the breast. We figure I'll be more comfortable--especially given that a girlfriend of mine has stage IV breast cancer. My mom has had benign lumps removed in the past. I don't like the idea of surgery that isn't 100% necessary, but I also don't like this unwelcome visitor hanging out. I'm supposed to take a few days to contemplate the situation and make a decision.
