Hi @brighterdays

In 2013, with stage 1 BC, clear lymph nodes, clear margins, BRCA2+ and double mastectomy, they told me no radiation. They told me if I had a lumpectomy, I would need radiation.

In 2020, my BC cancer returned in my chest wall and pectoral muscle. Tumor was removed, but there was a positive margin. Lymph nodes clear. Ki-67 50% this time, very aggressive. They did 37 radiation treatments, 28 regular plus 9 boost all on the side where my chest tumor was, about 8" x 12" area. I tolerated the first 20+ treatments very well (then things got a little rougher), but I think you'll do well with the 15 or 15 + 5. That was 2.5 years ago and I didn't have any lingering effects except drier than usual skin on that side. Calendula cream works great. Use it twice a day from day one even if you don't think you need it. Skin was darker after it healed, but that went away in a few months. Once you start radiation, the appointments are quick and easy. The actual radiation was about 2 minutes each time. Given that my cancer came back, I'd probably lean toward more treatment initially.

Best of luck in your decision and treatment. Blessings, Zebra
