Hi Rachel,
Try to stay positive. (Yeah, right - easier said than done, I know!) Most of these breast issues are not cancerous but it's still stressful to go through it - the waiting for an appointment, the waiting for a procedure, the waiting for the biopsy results.... It takes its toll on you.
I used to have a lot of fibrocystic breast disease - every self-exam was stressful and painful because all I found were lumps, lumps, lumps. Then every mammogram was a problem because the cysts always showed up as "suspicious" - then I'd have to wait for the radiologist or a 2nd mammogram or a biopsy and even surgery. For one surgery, they couldn't isolate some calcifications and they didn't want to operate before they could put in a tracking wire so they'd know what section to remove. So I spent 2 hours compressed in a mammography machine - compressed for 20 minutes while they developed the film, then they'd adjust the machine for 15 sections and then I'd be compressed for another 20 minutes, and so on. It's so frustrating when you, the woman, are at the mercy of the technology.
So I sympathize and I know how hard it is. I have managed to get rid of everything and my physician is thrilled - even she cannot find any more cysts. So that is behind me now.
I send you good thoughts hoping that your surgery will be quick and that the biopsy will show that this is nothing to be concerned about. Your mom had breast cancer but that doesn't mean that you will - remember that most of us women go through these stressful and frustrating times, but 99% of the time things turn out okay.
Hang in there.
