In addition to a lack of evidence-based benefit, many are downplaying the very real radiation risk. Take this typical exchange with a Florida “scan and tan” center:

Or “Come to Florida, for a scan and a tan,” flashes a Web ad for HealthTest Scan Center, where a pelvic, abdomen and chest scan will set you back $895, with a heart scan thrown in.

When Tania answered the phone at Boca Raton, Fla., office, I said I wanted information but thought I was healthy. She chuckled, “Everyone thinks that, but it’s just to make sure. Prevention is better than a cure.” What can a scan prevent? “Death,” she replied. And if my doctor refuses to prescribe it? “See our doctor [either Dr. Marc Kaprow or Rohtem Amir]. He’ll give you the OK.”

I asked Tania about radiation danger. “It’s minimal”¦with this machine,” she reassured. How often should I get one? “Talk to the doctor, but some people have them four to five times in a six-month period.” Why? “Some people are hypochondriacs,” she confided.
