Hello @hutchnjo2 chemo and in fact any treatment is a cost vs benefit decision each of us has to make, evaluate and re-evaluate. Different things are important to different people, and at 90 you certainly would have a different list than I had in my 30’s. I imagine that I would want to ask my doctor, what if I do nothing? What kinds of side effects would I have from this chemo? What can I reasonably expect to gain from chemo? I am sure you have more questions already. I might also get a second opinion, just to feel like I have all the information I need to make the best decisions for myself.
Do you live near a large cancer center or a teaching university where you might be able to get a second opinion? Do you have family, and how do they feel about all of this?
