As I and my fellow leukemia vets know, having had a variety of poisons pumped into our bodies ( think "Love Canal") puts us at a 30% higher risk of developing secondary cancers. We have to be checked, re-checked and checked again all the time. It costs a lot, but we live. And we add to the economy through job creation.
On my list is a Pet Scan, scheduled for early August plus a mammogram, a colonoscopy and a skin evaluation. In the Pet Scan, which I have yearly, they check for tumors throughout my trunk. I've yet to have had my head checked. I'm pretty sure it's empty.
