Welcome, @kruzer. I moved your question about radiation for skin cancer and side effects like fatigue to the Melanoma & Skin Cancer support group https://connect.mayoclinic.org/group/melanoma-skin-cancer/

I did this to connect you with other members who have had radiation like @pianist3 @psgstl @jseregny @grammato3 @katydid77 @cleveland26 so they can share their experiences with you.

Fatigue affects most people during cancer treatment. Cancer fatigue can result from the side effects of treatment or the cancer itself.

@kruzer. I'm glad you reported your side effects to your cancer team and that the nausea was managed quickly. Fatigue can be trickier to cope with. As someone who is used to being active, this can be hard to accept. But being an active, fit person will serve you well. You might have to be kinder with yourself and not expect to maintain the same level of activity while in treatment. Do what you can. Do you find pacing yourself helps?
