TLDR Prostate cancer prevention now focuses on healthy diets and some medications, not vitamins.
Over the past decade, the approach to preventing prostate cancer shifted from relying on vitamins and micronutrients, which proved ineffective, to emphasizing lifestyle modifications such as balanced diets and reduced dairy consumption, particularly favoring Asian or Mediterranean diets. This marked a significant change in prevention strategies. Additionally, chemoprevention using 5α-reductase inhibitors like finasteride and dutasteride significantly reduced prostate cancer incidence, although their use in practice was controversial.
