Looking for support or some insights on my decision.

I'll be honest. Sometimes I see women who have small areas of low grade DCIS who opt for a BMX, and I cringe a bit. It can be such a life changing surgery, in how it affects your body and your sex life and your relationships, and there can be complications and side effects that can linger on for years... it seems to me to be an over-reaction to an indolent tiny low grade non-invasive condition (many experts don't consider DCIS to be a cancer) that can be easily and fully treated with a small lumpectomy. Now, if there is a strong family history, if someone has a genetic predisposition to develop breast cancer (BRCA positive or something else), if someone has gone through years of biopsies... there are lots of reasons why it might make perfect sense for someone with a tiny low grade DCIS to have a BMX, but if none of these other conditions are there and it's just a 3mm grade 1 DCIS... yeah, I cringe a bit when I see that. But I keep that to myself because everyone needs to make the decision that is right for themselves.

However when it comes to breast cancer (including DCIS - my preferred definition, particularly for high grade DCIS, is that it's a pre-invasive cancer), I'm a big believer in "two strikes and you're out". To me, being diagnosed a second time means that there is something in one's breasts or one's body that makes the breasts fertile ground for developing cancer cells. I've been hanging around here long enough to have seen more than a few people who started with DCIS come back a 3rd time or 4th time, and it seems that each time, the diagnosis is worse. So in your shoes, I'd make the same decision.

I usually don't offer up my opinion on this subject because this is such a highly personal decision. Everyone needs to do what they feel is best and I don't want to influence someone to do something that isn't what they are most comfortable with. It's also so easy to offend those who've already made their choices, for example someone who did have a BMX for a small low grade DCIS, or someone who has opted for lumpectomies with a second or third diagnosis. But since you've said what you are thinking about doing, I thought I would offer up my thoughts - yeah, I'd do the same thing. I'd think, "Okay breasts, I gave you a fair shot, and you failed me. Time to go."
