A proposed guideline update from the U.S. Preventive Services Task Force suggests that women with an average risk of breast cancer should undergo screening mammograms every two years, starting at the age of 40.
This revision takes into account advancements in diagnostic technology and treatment, and marks a reversal of the panel's previous controversial recommendation in 2009.
At that time, routine mammograms for women in their 40s were discouraged, and biennial screening was advised to begin at age 50, unless a woman and her doctor agreed to earlier screening.
According to the statement, the incidence of breast cancer among younger women has been increasing, and advancements in digital mammography have enhanced its accuracy. Furthermore, improved treatments have led to higher survival rates.
Based on new computer models, it is suggested that initiating biennial screening at the age of 40, instead of 50, and ensuring that all eligible individuals undergo mammograms, could result in a 20% reduction in breast cancer mortality in the United States.
The benefits of early screening would be particularly significant for Black women, who typically experience more aggressive breast cancers and lower survival rates, as stated by the panel.
