A 10-year study found no higher risk for prostate cancer in men with BPH. Unsuspected prostate cancer is detected during surgery in about 15% of BPH patients, but the risk of this slow-growing cancer is high in all older men. Some estimates suggest that up to a third of men over age 50 have at least microscopic prostate cancer.
Still, there is some evidence that men with fast-growing BPH may be at higher than average risk for prostate cancer. This prostate condition is also associated with obesity, heart disease, and diabetes. Some experts suspect that insulin resistance may be the common factor in all of these conditions, including prostate cancer.
