I heard somewhere (can't remember where) that frequently holding a full bladder (not going to the bathroom when feeling the urge to urinate) for long periods of time can lead to Prostate cancer for men. I remember hearing that cab drivers and other professions where people have to hold it for extended periods of time are especially at risk for prostate cancer.
I am not sure if this is a myth or reality. I haven't been able to find much information on this.
Has anyone heard or read something similar? Any conclusive proof anywhere?
