The two side effects that I remember from rads (it's been almost 4 years), are getting a little pink and getting progressively more tired. I never really burned and I am fair-skinned. My radiation center was very generous in handing out lotions and I was very diligent about using them! I got a little itchy near the end and was given a special lotion (Regencare, I think) for that. I had plenty of plain white t's that I wore to keep my clothes from being stained by the lotions.
It took longer to park and get on a gown than it took to get zapped!
Glad to hear that your tumor is shrinking and that you're on the home stretch for chemo. xoxoxo Lynn
