How do age and density relate to breast cancer risk and imaging?

Breast density reflects how much fibroglandular tissue versus fat is present. Dense tissue appears white on mammograms, which can obscure cancers and lower imaging sensitivity. It’s also an independent risk factor: higher density means a higher underlying risk of developing cancer compared with fatty breasts. Density tends to decrease with age as glandular tissue is gradually replaced by fat, especially around or after menopause. So, density generally drops with age, while higher density both raises cancer risk and reduces the ability of mammography to detect cancers.
