A reasonable amount of exercise for majority days of the week may add to a lesser danger of prostate cancer, and lower grade tumors among those men who are supposedly detected with the disease following biopsy. This is as per the researchers at Duke University Medical Center and the Durham Veterans Affairs Hospital.

The finding apparently adds more fuel to the continuing dispute over whether exercise could provide any advantage at all among men looking for ways to avert prostate cancer.

Stephen Freedland, MD, a urologist at Duke and the Durham VA and the senior author of the paper, commented, “There have been dozens of studies about the value of exercise in lowering risk of prostate cancer, and some of them quite large, but the bottom line is that they’ve left us with mixed signals.”

About 190 men had to go through prostate biopsy at the Durham Veterans Affairs Medical Center. After analyzing them, the investigators discovered that men who often occupied themselves in reasonable activity were thought to have considerably less chances to be detected with prostate cancer, and if they were, they apparently had fewer odds to have aggressive disease, which may be described as a tumor with a Gleason score apparently equal to or greater than 7.

The level of exercise was apparently assessed via a questionnaire before the biopsy.

Questions regarding the regularity, period and force of any exercise during a usual week were apparently incorporated in the survey. The kind of activity was apparently planned in three ways. The first one was mild like easy walking and yoga. The second one was moderate such as brisk walking and tennis while the third one was strenuous i.e. running and vigorous swimming.

But most of the men apparently were not up to the standards of the American Heart Association guidelines for the smallest quantity of exercise required every week. Researchers established that about 58 percent of the men were said to be sedentary, meaning they supposedly exercised less than the corresponding of one hour per week of simple walking. Around forty-six percent appeared to be as moderately active and only roughly 33 percent seemed to be pretty active.

After regulating for age, race, weight, PSA score, family history of the disease, and other variables, it was apparently discovered that men who apparently exercised for more hours per week were said to be considerably less probable of having cancer on biopsy. But investigators established that any quantity of exercise was believed to be linked with a trend towards a lesser threat of prostate cancer. Among men who were apparently found to have cancer, even exercising as little as one hour per week of easy walking was supposedly connected with a lesser possibility of acquiring a high-grade disease.

Jodi Antonelli, MD, a urology resident at Duke and the lead author of the research mentioned, “This is a relatively small study — and it is not a screening study — so it may not be appropriate to apply our results to a general population. In addition, it is impossible to state that exercise alone was responsible for the benefits we observed because participants who exercised might also have engaged in other behaviors linked to better health, like adhering to good diet. That means we can not clearly identify a causal relationship.”

While the outcomes apparently points out to an association between exercise and prostate cancer risk, Antonelli believes that they should be understood with an alert mind.
