Prostate cancer (PCa) is a prevalent malignancy in men worldwide, and both androgen deprivation therapy (ADT) and radiotherapy (RT) are key components of its management. However, these treatments significantly affect bone health by inducing bone mineral density (BMD) loss, osteopenia, osteoporosis and increased fracture risk. ADT promotes a high bone turnover state through hormonal suppression and molecular mechanisms involving increased RANKL expression and osteoclast activation. RT generates direct cytotoxic damage and inflammatory changes that compromise bone microarchitecture. Combined ADT + RT exerts synergistic detrimental effects. This narrative review synthesizes the molecular basis, clinical evidence, preventive strategies and emerging technologies related to bone health in men with PCa undergoing ADT and/or RT.
