Hi @RosaPink. Welcome to the forum. I hope you find it to be as warm and helpful as I have.
I had ER+ BC, and my diagnosis didn't automatically warrant chemotherapy. However for a variety of reasons (read my bio) it was on the table. My doctors suggested I do a genomic test. That's where they look at the specifics of your cancer to assess the likelihood of recurrence/spread. The one that is used in triple neg is called MammaPrint. These tests are not on Medicare or covered by private health insurance and so cost several thousand dollars. If you can manage the price, perhaps you coukd ask your oncologist if they think it would be useful.
To chemo or not is a question that comes up a lot here. Find out what chemotherapy regime you'd be having, and make yourself aware of the risk factors and side effects. If you do a genomic test you'll be clear if it's warranted and the decision is a no brainer. But if you don't, then for me it comes down to the clincher question: if I don't have chemo and my cancer comes back, will I be tortured by the knowledge that I chose not to have chemo?
There is no right or wrong. It's a perfectly legitimate decision to not have chemo. It's all about knowing yourself and what your tolerances for the road not taken are. No regrets, either way.
All the very best, and please continue to throw out the questions and ponderings. This is a great hive mind! Big hug, K xox
