Cancer and treatments for cancer can have a significant impact on bone health in both children and adults. There are emerging data that bone mineral density is often reduced in survivors of childhood cancers and survivors of both solid tumours and haematological malignancies in adults. Fracture rates in childhood cancer survivors have not been shown to be increased. Older adult cancer survivors, particularly those treated with aromatase inhibitors and androgen deprivation therapy, do have increased fracture rates. This talk will provide an overview of current evidence and guidelines with regards to bone health assessment, monitoring and treatment in both survivors of childhood and adult cancer. The emphasis will be on a practical approach to bone health in an individual patient, taking into account age, imaging, cancer type and treatments received.
