The role of diet in breast and prostate cancer survival

Abstract

Cancer is a leading cause of death worldwide. Breast and prostate cancer are two of the most common malignancies and contribute significantly to the societal and economic burden of cancer. Various ethnic and racial groups are affected differently by overall cancer incidence and mortality. Racial disparities are evident for breast cancer survival and both prostate cancer incidence and survival. The reasons for differences in cancer incidence and survival are not entirely clear. However, diet plays an important role in cancer prevention and survival and may also be implicated in racial and ethnic disparities. Ecologic, case-control, cohort, and randomized, controlled studies have demonstrated the benefits of a low-fat, high-fiber diet for breast and prostate cancer survival. A plant-based diet, generally low in fat and high in fiber, may offer survival benefits for both breast and prostate cancer. Further research is required to establish effective interventions that promote healthy dietary choices that enhance cancer survival.
