Prostate cancer is a burden on society. Its prevalence can reach up to 80% in males aged 70 years and older. Current screening programs based on prostate-specific antigen testing lead to overdiagnosis and overtreatment with uncertain benefits on survival. Androgenic alopecia is also highly prevalent in elderly males. Observational studies have found that androgenic alopecia is linked to prostate cancer, but studies have been conflictual. Further research should focus on finding the exact mechanism linking these two pathologies. This should help clinicians improve screening programs and guide research into novel molecules to help in the prevention and treatment of both androgenic alopecia and prostate cancer.
