Over 45? Sit down, relax

Exercise May Lead To Faster Prostate Tumor Growth

What all middle aged men have been waiting for: an excuse to sit around and get fat.

The experimental model that this is based on is not exactly close to real life, though:
The researchers implanted prostate tumors subcutaneously in the flanks of 50 mice and then put half of the mice in cages with exercise wheels and half in cages with no wheels. All mice were fed the same diet. On average, the exercising mice ran more than half a mile each day.
So, next thing is to try to do this a bit more realistically:
The researchers are currently conducting a validation study, in mice, in which tumors are injected directly into the prostate, thereby better simulating human prostate cancer, Jones said.
Just how big is a mouse prostate? How do you tell if it's enlarged?
