Hi there
Your medical team can give you the statistics on whether further treatment is worth it for your situation - I was recommended radiotherapy and hormone therapy ( Letrazole) but not chemo.
The side effects from radiotherapy were minor and although the hormone therapy has given me some issues with my right thumb I am managing them.
I want to do whatever I can prevent a recurrence but understand some people have such bad side effects treatment has to be stopped.
You won’t know until you start the treatment but most people get through it .
Ask lots of questions of your medical team and on here ang good luck .
