Which imaging method is recommended for suspected breast cancer in individuals over 35 years old?

Mammography is recommended for suspected breast cancer in individuals over 35 years old because it is specifically designed for detecting breast abnormalities, including malignant changes, in this demographic. Mammograms utilize low-dose X-rays to create detailed images of the breast tissue, allowing for the identification of tumors that may not be palpable during a physical examination.

The efficiency of mammography in detecting breast cancer in women over 35 stems from the increased risk associated with age. This imaging modality has been proven to reduce mortality rates from breast cancer through early detection and can identify cancers that are often small and not yet symptomatic.

Other imaging methods may have specific roles but are less effective or more suited for different situations. For instance, while ultrasound can be a valuable adjunct to mammography, particularly in evaluating known abnormalities or in dense breast tissue, it is not typically the first-line screening tool. MRI is highly sensitive and is used in specific populations, such as those at high genetic risk, but it is not routinely used for initial screening in the general population. CT scans are not indicated for breast cancer screening or diagnosis as they do not provide the same level of detail for breast tissue as mammography does.
