The study participants (nearly 70,000) were tracked for more than a decade, which enabled researchers to record data of a man's adult weight changes in comparison to his initial weight at the beginning of the study.
The men in the study who had lost more than 11 pounds had lowered their risk approximately 42 percent for developing the aggressive form of prostate cancer in comparison to those whose weight stayed the same during the same time period.
According to lead researcher, Dr. Carmen Rodriguez, from the American Cancer Society, "Whether it's exactly 40 percent, we don't know, but they lower their risk when they lose 11-plus pounds. We feel confident, at least in this population, that was real."
Prior studies found that obesity in men increased the aggressive prostate cancer risks. Apparently this is the first study to find that weight loss may be related to lowering a man's risk for this type of prostrate cancer.
According to WebMD, aside from skin cancer, prostrate cancer is the most common cancer found among men in the U.S., and it is becoming more commonplace as men age. Now the link to being overweight seems to make the risk even higher.
Previous studies have also indicated several links between weight loss and various lowering of cancer risks, in particular that of breast cancer in women.
