Thanks, AA, I think it's important to remember the risks associated with screening. I didn't know that CTscans were associated with so much radiation, that's scary. MRIs are a better in terms of less radiation exposure. However, even MRIs with contrast dye are risky for those in renal or kidney failure due to the galadium dye. It's all kind of scary what we expose ourselves to due to having cancer, including toxic chemotherapy. I think as you and I get further out in survival, certainly risky diagnostic screening should be used as a last resort when pain persists beyond several months without relief.
