Doctor: Regular sexual activity may reduce prostate cancer risk by 20%

Prostate cancer remains the most common malignant tumor among men worldwide, but experts say several risk factors can be significantly reduced through lifestyle choices. In an interview with Gazeta.ru, oncologist Roman Leonenkov from the Napalkov Oncology Center and the Onkologika Foundation stated that regular sexual activity can lower prostate cancer risk by up to 20%.

Studies comparing men with daily sexual activity to those engaging in sex once a week showed a clear decrease in risk for the more active group. Frequent ejaculation may limit stagnation in the prostate and help eliminate potentially harmful compounds.

However, Leonenkov emphasizes that sexual activity is only one aspect of prevention. A balanced diet rich in vegetables, fruits, and omega-3-rich fish—such as salmon and herring—and low in animal fats can significantly reduce the likelihood of developing aggressive prostate tumors. Physical exercise and maintaining a healthy weight play equally important roles.

The doctor highlights several warning signs men should never ignore: frequent nighttime urination, weak urine flow, the sensation of incomplete bladder emptying, blood in urine or semen, and pain in the pelvis or lower back. In such cases, men should discuss PSA testing with their doctor. PSA screening is recommended for all men over 45, or from age 40 for those with a family history.

Regarding testicular cancer, Leonenkov notes that the primary risk factor is cryptorchidism—testicles that fail to descend properly after birth. Early surgical intervention is key to prevention, and any change in testicle shape or density requires prompt medical evaluation.

Leonenkov points out that many men seek medical help only after pressure from their wives or daughters. “Family support is crucial. Men often ignore symptoms until the disease progresses,” he said.

He believes that open discussion about men’s health and debunking myths surrounding urological examinations can save lives. “If we talk more about prevention and modern, effective treatments, men will be less afraid to undergo check-ups, and serious cases can be detected much earlier,” the doctor concluded.
