Breast density refers to the amount of fibrous and glandular tissue compared to fatty tissue in your breasts. Women with dense breasts have more glandular tissue, which naturally feels firmer to the touch. This is extremely common, especially in women under 40, and is usually just a normal variation in breast composition. Many factors influence density, including age, hormones, pregnancy, breastfeeding, and genetics. Dense tissue usually is not painful and does not cause noticeable symptoms.

The only challenge with dense breasts is that they can make mammograms a little harder to interpret. Dense tissue appears white on a mammogram, and some abnormalities can also appear white. This means certain changes may not stand out clearly. This does not mean something is wrong. It simply means your doctor may recommend additional imaging such as an ultrasound for a clearer view. Ultrasound helps detect lumps or cysts that may not be visible on a mammogram. Having dense breasts is not a medical problem, and there is no need to worry. It only means you may need slightly more personalized screening so that your doctor can monitor your breast health accurately.
