Radiation Thread

I'm starting radiation on Monday and I was trying to find the thread on dealing with radiation, but I'm not coming up with it?  I had a PET scan on Friday and I'm stressing while waiting for the results.  My insides are still not feeling great almost 4 weeks after chemo and I don't know if it's that or spreading cancer.  I haven't read alot of good things about carcinosarcoma, so it's hard not to think about.  Does anyone remember the name of the Radiation thread that was so helpful.  Thanks!
