[ RadSafe ] Prostate Cancer Linked to Diagnostic X-rays

[HOWARD.LONG at comcast.net]

Common cause, rather than cause-effect is more likely with the young men's prostate cancer association with x-rays of hip, colon etc.  Testosterone increases both. Risk sports increase hip x-rays. Aggressiveness disrupts the colon.

 Also, the animal and cell experiments  of  Pollycove, Bobby Scott and others show the opposite: less cancer with more x-ray (up to 10-20 x usual background. I'd want to stimulate the body defenses in my spleen with 75 rem 2x/week for a month if I had a prostate cancer. Watch for an article soon by Cuttler and Pollycove.
