How often should individuals at moderate risk of breast cancer consider having a mammogram according to guidelines?

Individuals at moderate risk of breast cancer are advised to have a mammogram every two years according to current guidelines. This recommendation is based on the balance between the benefits of early detection of breast cancer and the potential risks associated with more frequent screening, such as false positives and unnecessary anxiety. The biennial screening regimen allows for regular monitoring while minimizing exposure to radiation and reducing costs associated with more frequent imaging.

Screening every two years is particularly beneficial for those at moderate risk, as it provides ample opportunity to detect changes or developments in breast tissue while still allowing for a manageable schedule that aligns with risk factors. Additionally, this interval has been shown to effectively catch cancers at a stage where treatment is most successful.
