How often should women aged 40 and older have a mammogram?

Women aged 40 and older should have a mammogram annually because regular screening is crucial for the early detection of breast cancer. The recommendation for annual mammograms starting at age 40 is supported by various health organizations, including the American Cancer Society and the U.S. Preventive Services Task Force.

An annual screening allows for the monitoring of any changes in breast tissue over time, increasing the likelihood of identifying potential issues at an earlier stage when treatment is often more effective. This regular schedule also helps in establishing a consistent baseline for each individual's breast health, making it easier to spot any abnormalities.

By following this annual screening guideline, women can engage proactively in their breast health, ensuring that any potential concerns are addressed promptly.
