Hi all lovely ladies. I was diagnosed with 15mm low grade dcis and opted for double mastectomy due to family history ..maternal grandmother and great aunt had breast cancer. Post mastectomy it was upgraded to 18mm intermediate /high but no microinvasion. Surgeon believes no further treatment needed. Genetic testing only found an u certain variant so not really considered to have the main genes. Not sure why I still don't feel enough is done. Maybe I am overstressing..I asked the surgeon if I do needto go on Tamoxifen and he believes no. Not really sure what to do. Wanted to see if anyone has been in this situation?
