submitted by: admin on 10/14/2013
Screening does not significantly reduce prostate cancer deaths but it does lead to overdetection and overtreatment.

The era of the PSA is over.

submitted by: admin on 04/08/2015
No one wants to get colon cancer and colonoscopy has been touted to be the best way to find asymptomatic precanceous and cancerous lesions of the colon that could be lifesaving.
