I don’t remember exactly but was still under treatment for my right breast. The lobular cancer never showed on a mammogram. It doesn’t. My left breast was checked cause I had it in right breast. I wasn’t familiar with mirroring. I had the double mastectomy because I didn’t think my body could handle radiation right after chemo. Judging from 2 friends who had radiation now have fibrosis in the lungs. I didn’t want to go through that. Being I did the double mastectomy I didn’t need radiation.
