What is mammography?

• A. A radiographic examination of the breasts to detect tumors or precancerous cells
• B. A radiographic examination of the brain
• C. A radiographic examination of the liver
• D. A radiographic examination of the bones

Answer: (A)

Mammography is a radiographic examination that uses low-dose X-rays to image the breasts, helping to detect tumors or precancerous changes. It serves both screening and diagnostic purposes—screening to find cancers early in asymptomatic individuals and diagnostic imaging to evaluate a lump, nipple discharge, or other breast concerns. The images produced focus on breast tissue, looking for masses, calcifications, or architectural distortions that could indicate cancer or benign conditions.

This differs from imaging of other body areas. A radiographic exam of the brain, liver, or bones targets those specific organs or structures, not breast tissue, so those options describe entirely different studies.
