So sorry to hear this. I had a mastectomy on my left breast and it was Stage 2 but I was in my early 40’s so they did chemo and radiation. I did genetic testing back then but they only tested for BRAC 1 and 2 which I didn’t have. My oncologist just requested that I have genetic testing again and this is when they found the CHEK 2 mutation. The genetic counselor suggests yearly MRI’s now and a colonoscopy every 5 years. My mom who is 82 is going to be tested now for free. She has had no cancer of any kind. I am scared about the cancer return especially even after this length of time. I’m really scared at this point to have another mastectomy. I’m 57 currently. So they found a lump after 11 years in the other breast and you had a lumpectomy and radiation? Do they suggest having a mastectomy? What are the odds it would come back again?
