Technically, I suppose maybe it is more difficult if one is older, but so many of us are in our 60s and we are doing treatment, tolerating treatment, dealing with the
side effects, and are finishing treatment
. I still think the
key is recognizing and treating the
side effects immediately (rash, nausea, depression, anemia, etc.). If they are not treated, they can snowball rapidly.
So, to answer your question, no one knows which or how many side effects they will get until they treat.
