What is a common indication for performing a mammogram?

A mammogram is primarily indicated for screening for breast cancer. This imaging technique utilizes X-rays to detect abnormalities in breast tissue, allowing for the early identification of potential malignancies. Early detection through regular screening can significantly improve treatment outcomes for breast cancer.

The focus of a mammogram is specifically on breast health, making it a crucial tool in the fight against breast cancer. Regular screenings are recommended for women, especially as they age, because the risk of developing breast cancer increases.

The other choices pertain to different areas of medical evaluation. Evaluating lung function relates to respiratory tests such as spirometry, assessing brain activity involves imaging techniques like MRI or EEG, and monitoring bone density typically involves DEXA scans. Each of these procedures targets distinct health concerns and does not involve the breast tissue directly, underscoring why screening for breast cancer is the correct indication for a mammogram.
