I have not chosen to take AI or tamoxifen because I couldn’t tolerate the tamoxifen and I have osteoporosis so not eligible for AI unless I take Zometa with it. My Oncotype was 14. IDC estrogen +, 15 mm, negative nodes and grade 2. I am told grade doesn’t really matter anymore unless grade 3. Doctors are relying more on Oncotype score. I have 8% chance of recurrence without endocrine therapy . I was diagnosed at age 67. I am almost 69. I am involved with Signatera . Look it up.
