@orienteer I agree with @triciaot with an addition from my personal history.
I was young, in my 30’s when I was first diagnosed. This means I had a lot more years to live with the decisions I made. I honestly wish I had decided to treat more aggressively in the beginning, although in my case I would have had to fight the medical establishment and chose to accept the less aggressive surgery.
The best doctor I ever had said “the only good decision is an informed decision” with my 20+ years of hind sight I would not settle on a decision until I had been to a cancer center and had every tidbit of information about my diagnosis. Don’t decide until YOU are comfortable with the decision.
Do you live near a large cancer center?
