Which factor mentioned influences the sensitivity of mammography?

Age is a significant factor that influences the sensitivity of mammography because breast tissue changes with age. Younger women tend to have denser breast tissue, which can make mammograms more challenging to interpret and reduce sensitivity. As women age, their breast tissue generally becomes less dense due to changes in hormonal levels and the natural aging process, which makes it easier to detect abnormalities such as tumors during mammography.

In terms of mammography screening guidelines, age is often a primary consideration for when to begin regular screenings, as the risk of breast cancer increases with age. This relationship highlights the importance of tailored screening strategies to optimize detection rates, particularly in different age groups. Adjustments in screening protocols may also occur based on the age of the patient to account for variations in breast composition and associated cancer risks.
