My tumor was Stage II (don't know what type) with clean, but close, margins. I went ahead with the radiation which started 4 weeks after the thymectomy. I was prepared for alot of side affects, but I really didn't have any except a slight "sunburn" on my chest. I didn't notice that I was more tired than usual (other than mg tiredness)

The initial appointment for therapy was a bit traumatic because I didn't realize they would be radiating me from front, back and under both arms to get my entire thymus area. After I got over that, the actual radiation was pretty straight forward.

I went back to work with about 10 treatments left (about 8 weeks after surgery) and just took a long lunch every day for treatments.

I made my choice to have the radiation, but everyone is different. I did a lot of research on thymic cancer and decided I didn't want to take a chance on that aggressive cancer coming back at any time.

Good luck on your decision.
