Exercise can apparently lessen the rate of cancer cell growth and even help prevent its recurrence.

I do recall a time where I rang my best friend (on a day off) and told her I was tired...she told me to have a nap.... So I went for a 40 min walk instead and, hey presto, my energy came back for the rest of the day. Taught me a valuable lesson but there are days (not many) where I will have a power nap, when and if I can.
Another interesting personal fact, I have more energy during the day when I exercise first thing in the morning. That's probably the lovely, feel-good endorphins.
I hope this might help some of you and hope you get thru the fatigue soon. Alex xx
