My oncologist was completely happy to stop at 11, most of the oncology nurses were happy with 9 or 10. I did all 12 only because I found a lump just before number 11. It was nothing of any concern (once it had been biopsied!) but rather consolidated the wish to do everything I could to avoid any recurrence. If the patient can live with the possibility of permanent effects (after seven years I am pretty sure mine are) then OK, but not knowing exactly what those would be is tricky. I don’t mind the fact that I really can’t run (messages to the brain that I am about to fall can be counteracted when I walk but not effectively if I run), can’t wear heels or emulate The Queen and stand still for hours, as I am still here and have no actual pain. Not being able to use my fingers effectively (typing, dressing etc) would be something else altogether. Making hard decisions is part of the process I am afraid. The views of the person on the receiving end are vitally important.
