BooKaren,

It took about three years for me to feel the same energy levels that I had before radiation treatment. However,I had a series of 5 surgeries over a 4 year period, so it may have taken longer for me. I swear sometimes I get more tired when I'm out in the sun for extended periods, but it could just be my imagination. I have found that increasing my physical activity had helped "kick start" my energy levels to where they were pre-cancer. While I don't think I will ever be the same, at least I can go for a long walk without wanting to stop and rest.
