Hi @jomaree,
Welcome lovely. You are definitely in the right place for support and fantastic advice. It is very confusing at the beginning, so many things to decide and a whole other language to get your head around.
Most of us call it the rollercoaster as it is the best word to describe your feelings and emotions.
I too had lumpectomy,axillary clearance, rads and I did do chemo as the rotten thing was already through 5 of the lymph nodes and surrounding tissue. The increased benefit for me was 11%. Even then I ummed and aahhed about it.
Chemo is a hard slog. It is very hard on your body. There are side effects that vary from person to person and some hang around for years.
Be guided by your team. They see enough of this to know whether or not the benefits of the treatment are worth the risk.
All the best lovely.
