Obesity is not only a risk factor for prostate cancer, it can also increase the risk of recurrence. Exercise and physical activity are beneficial by supporting weight loss, enhancing pelvic circulation, improving immunity, and reducing fatigue.
The most effective cancer diet is low in red meat and dairy and high in fruits and vegetables. Broccoli in particular has been shown in clinical trials to specifically help prevent prostate tumor. A vegetarian diet has been shown to be effective in some cases. There is conflicting information on soy and soy isoflavones. Dietary soy is associated with a lower risk of developing cancer. The effects of concentrated soy extracts and other phytoestrogens are less clear. This may due to the fact that men eating a Western diet (full of meat and low in vegetables) have a different population of bacteria inhabiting their gut. These bacteria may not effectively break down soy into its active metabolite, genistein.
Men eating a traditional Japanese diet tend to experience greater benefit from soy in terms of preventing prostate tumor because they have been eating soy foods as a part of their daily diets for years, and therefore are more likely to have a population of gut bacteria that effectively metabolize soy isoflavones into genistein; men who incorporate soy foods in the diet abruptly may not receive the same benefit. A 2008 study involving men with prostate tumor demonstrated that decreased consumption of saturated fat and increased consumption of vegetable proteins slowed the growth of cancer and increased quality of life.
Studies demonstrate that physical activity is important in preventing prostate tumor. In one large prospective study, men over 65 who exercised the most had the lowest risk of cancer. Exercise will also help maintain normal body weight as obesity is a risk factor. In one study involving men who previously had prostate tumor, those with the highest BMI had the highest risk of developing a recurrence.
