I would say your best bet is to talk to your doctor. They will be able to tell you about your treatment plan and what works for you.

If you say what form of cancer you have, people here who have also had the same kind of cancer will be able to tell you about their experiences, but of course, that comes with a certain warning as your experience may not be the same as theirs. But they will at least be able to suggest some things that you could ask your health team about.
