Prostate cancer has the highest prevalence of any non-cutaneous cancer in the human body and essentially all men with circulating androgens will develop microscopic prostate cancer if they live long enough.

Abstract

Prostate cancer has the highest prevalence of any non-cutaneous cancer in the human body and essentially all men with circulating androgens will develop microscopic prostate cancer if they live long enough. Aging, considered as an impairment of body functions over time, caused by the accumulation of molecular damage in DNA, proteins and lipids, is also characterized by an increase in intracellular oxidative stress due to the progressive decrease of the intracellular ROS scavenging. The aging damage may eventually appear in age-related health issues, which have a significant impact on the independence, general well-being and morbidity of the elderly. The association of aging with prostate cancer is undisputable as well as the association of aging with oxidative stress. Nevertheless, supportive evidence linking an increase in oxidative stress with prostate cancer is still scarce. This review is a comprehensive, literature-based analysis of the association of human prostate cancer with oxidative stress. The objective was to examine the involvement of reactive oxygen species in the mechanisms of prostatic carcinogenesis since the understanding of risk factors for prostate cancer has practical importance for public health, genetic and nutritional education, and chemoprevention.
