Risk Factors Which Have Little Effect On Prostate Cancer

What Cause Prostate Cancer?

There have been many attempts to establish links between various factors and the risk for prostate cancer. The factors listed below are what many would think are risk factors for prostate cancer, but in reality they have little or no effect on the risk for developing prostate cancer.


A vasectomy is a surgical procedure performed to make a man infertile. Some studies have suggested that men who had a vasectomy before the age of 35 may have a slightly increased risk for prostate cancer.

However, results of studies to establish this link have been mixed and are not strong enough to warrant recommendation that men wait to have this procedure or reverse the procedure.


As cigarette smoke contains cancer-causing chemicals (also called carcinogens), some scientists thought smoking may be a risk factor of prostate cancer. In reality, smoking increases your risk of developing lung cancer, as well as other cancers, such as prostate cancer.

Although men who smoke may have a higher mortality rate from prostate cancer than non-smokers, evidence does not suggest a link between smoking and the development of prostate cancer. Smoking has been clearly linked to other illnesses including cancers of the lung, mouth, throat, bladder, kidney, pancreas, and stomach, as well as heart disease, pneumonia, cataracts, and a serious from of gum disease called periodontitis.

Sexual Activity

 This leads to many men asking if a man’s level of sexual activity has any impact on his risk for developing prostate cancer.

Different groups of men have been studied in an effort to establish if sexual activity is a prostate cancer risk factor. Studies on married men with or without children, unmarried men with one or more sexual partners, young men, older men and so on did not provide any strong evidence of a relationship between sexual activity or inactivity and the risk for prostate cancer.

Viruses And Other Infections

Many viruses can infect the prostate, just as they can infect any other tissue in the body. Viral infections can cause inflammation and problems with urination.

However, there are few reports of these infections resulting in higher risk of prostate cancer. Recent studies have looked at a potential relationship between HPV infections in men and the risk of prostate cancer. However, results are inconclusive and more studies are expected to be conducted over the next few years.
