Jim: Just a note here.
I had chemo therapy just before I started chemo/radiation for 7 weeks. The chemo reduced my tumor and canerous surrounding tissue 70%, but I'm still getting radiaton based on the original PET-CT scan. Why? As my doctor explained, all it takes is one remaining cancer cell for it to spread. Think about it!

Also, do some research into the different types of radiation machines. The radiation machines today are very targeted, and a lot of advances have been made to spare healthy tissues. CCC usually have more than one type of machine available to their patients.

Good Luck
