I am male breast cancer survivor, my oncotype is 34. It was suggested I get chemo (4 rounds) plus Tamoxifen. I was stage 1, no impact to lymph nodes. I am on year 2 of tamoxifen 10 mg.
I have known many women that skipped chemo which led to cancer reoccurrence. I would speak with your oncology team on risks. Men similar to me, pursued chemo, tamoxifen and some also had radiation.
