Understanding Breast Density
Breast density refers to the ratio of fatty tissue to fibrous and glandular tissues in the breasts, with dense breasts having more of the latter. This classification is crucial as it affects mammogram effectiveness.
Approximately 40-50% of women aged 40 and older have dense breasts, a condition that is normal and not indicative of any health issues by itself.
Implications and Actions
Dense breast tissue can obscure cancer on mammograms and slightly increase the risk of developing breast cancer, though it doesn't affect the likelihood of dying from it.
Women with dense breasts are advised to continue regular mammograms and discuss with their doctors the potential for additional screenings like ultrasound or MRI, depending on individual risk factors.
