@songsparrow you can still have an Oncotype (or Mammaprint). After 5 years of meds you can have the Breast Cancer Index and/or Prosigna Assay. I had three tests done with my surgical pathology specimens. They are still available to you.

I read that cancers that are less than 1 cm, grade 1, and highly ER positive, HER2-, may not need an Oncotype. The decision on chemo is clearer and the risk of recurrence is probably low. If you meet those criteria I can try to find it.

Otherwise I wonder why your doc did not do one.

@callalloo As I wrote on another thread, I think these decisons depend on a lot of factors, including the severity and genomic make up of our cancers.

@frogjumper I was 63 when I was diagnosed and did letrozole for 5 years. I wanted to do more but a test told me no further benefit. I felt safe on them. I had very few side effects. Most of my friends with cancer also tolerated them well. Just another point of view.
