Federal Law Mandates Breast Density Mention in Mammogram Reports
Breast density, a crucial factor in breast cancer detection, has long been overlooked. As of September 2024, federal law now mandates that mammogram reports mention breast density and suggest additional imaging for dense breasts.
Breast density refers to the ratio of fibrous and glandular tissue to fat in the breast, not breast size. Dense breast tissue appears white on mammograms, making it harder to spot abnormalities. Women with dense breasts are two to three times more likely to develop breast cancer, though mortality rates remain unchanged.
Risk factors for breast cancer include family history, gene mutations, and lifestyle choices, with about one in five cases being preventable. Factors increasing the likelihood of dense breasts include younger age, pregnancy, breastfeeding, hormone replacement therapy, and lower body weight. About 40% of women have dense breasts, a condition that can change over time.
The American College of Radiology recommends yearly mammograms starting at age 40, with additional screening based on risk factors and doctor's advice. Since 2024, the Swiss Federal Office of Public Health (BAG) has required mammography reports to indicate breast density and suggest additional examinations for dense breasts.
Breast density, a significant factor in breast cancer detection, is now receiving the attention it deserves. With federal laws mandating its mention in mammogram reports and the recommendation for additional imaging for dense breasts, women can now be more informed about their breast health.
