Sorry to hear that rotten dog of a cancer is back on you. Radiotherapy sounds a lot better than chemo though, at least you can have not a bad quality of life and that's really what its all about. My dad is same age as your mum was and has the bone cancer. When I finished my chemo in April my dad started chemotherapy and he had continued to have it and has another couple of doses to go. His oncologist is telling him nothing though and will not commit to if or when chemotherapy will end. Dad did his lolly last week and went what the hell is going on? The oncologist will review him with scans on the 8th. It can be so frustrating just living in a twilight of life. Fight on Sheryl and don't take any evasive rot from doctors.
