Prostate cancer is one of the most commonly diagnosed cancers in Canada, with 24,000 new cases estimated for 2015. Prostate cancer patients often live with uncomfortable side effects of treatment, such as a decrease in bone health, weight gain, and challenges to their interpersonal relationships. Nutrition can improve outcomes for PCa survivors; however, dietary interventions for prostate cancer patients are limited. Therefore, this is a feasibility study that tests the impact of an innovative intervention to promote healthy nutrition and weight control for prostate cancer survivors and their partners.
