Final answer:
Mammography is the primary radiographic procedure used to screen for breast cancer. It is particularly effective in older women and can be supplemented with MRI to improve detection rates. Routine screening is generally advised for women aged 50 and over.
Step-by-step explanation:
The radiographic procedure most commonly used to screen for breast cancer is mammography. Mammograms are specialized x-rays of the breast tissue designed to detect abnormal growths or changes in breast tissue. They are particularly effective for older women, where contrast due to the presence of more fatty tissue in the breast can make lumps or tumors more visible. In contrast, dense breast tissue in younger women can make it more difficult for mammograms to provide clear results. As an adjunct to mammography, MRI (Magnetic Resonance Imaging) is sometimes used to improve detection rates and reduce false positives. However, routine screening mammograms are typically recommended for women aged 50 and older, as annual mammograms can help catch breast cancer early and significantly improve the chances of successful treatment.
