Molecular Mechanisms of Coffee on Prostate Cancer Prevention

BioMed Research International, Volume 2022, Issue 1, 2022., 2022
Prostate cancer (PCa) is one of the most common types of cancer among men, and coffee is associated with a reduced risk of developing PCa. Therefore, we aim to review possible coffee molecular mechanisms that contribute to PCa prevention.
