'Male Lumpectomy' May Help Some With Prostate Cancer

In the study, 180 men who'd had a standard biopsy underwent 3-D biopsy. The study found that 70 percent of the men would have their prostate cancer treatment changed by the information gleaned from the 3-D procedure.

For example, more than 50 percent of the men whose standard biopsy found prostate cancer on one side of the prostate also had cancer on the other side of the prostate, which was found only by the 3-D biopsy.

For the procedure, a grid is placed over the skin between the rectum and the scrotum, allowing a doctor to accurately map the location of each biopsy core that is removed. The grid is more precise in determining the exact location of cancer, Onik said.

Brooks said that, of the two procedures, "the 3-D prostate mapping biopsy is probably closest to having a clinical impact."

"It makes you wonder," Brooks added, "if these findings are replicated by other studies, how many men are being significantly under-treated?"
