Fact is everyone is different, every situation is different and making blanket statements regarding whether someone should or should not exercise during treatment is idiocy. People are beginning to sound like ignorant medical professionals on this thread or worse yet, physical therapists and personal trainers.

The American Cancer Society has pointed to several studies that show the psychological and physical benefits of exercise during treatment...notably decreased fatigue and improved sense of well being. However depending on what medications a patient is on and the side effects they may be experiencing, exercise wouldn't be recommended.

Let's take for example if you are on a duralgesic patch medicine delivery system that is heat activated. Raising your body tempature results in the release of more medication into your blood stream and potentially harming you when the spike in medication hits you after working through your skin to your bloodstream.

Or for example you are on high doses of pain meds like many of us have experienced...even walking without assistance can be tricky and potentially dangerous. I had a goal to exercise throughout treatment as I was an exercise fanatic precancer. Try exercising on 200mcg/hr of fentanyl and 60mg of oxycodone for breakthrough pain...even walking was difficult.

Working closely with the head of a patients medical team is the best advice anyone could give...let the medical professional that is most familiar with a patients treatment and overall wellbeing be the judge as to whether exercise is appropriate or not.
