Radiology Practice Test

What is the typical purpose of performing a mammogram?

1. To examine bone density

2. To screen for breast cancer

3. To check for lung diseases

4. To assess heart function

The correct answer is: To screen for breast cancer

A mammogram is primarily utilized as a screening tool for breast cancer. This imaging technique uses low-energy X-rays to create detailed pictures of the breast tissue, enabling radiologists to detect abnormalities such as masses or calcifications that could indicate the presence of cancer, often before any physical symptoms arise. Early detection through regular mammograms significantly increases the chances of successful treatment, as most breast cancers found through screening are diagnosed at an earlier stage. While other imaging techniques are designed to assess different parts of the body, such as bone density, lung diseases, or heart function, these are not the focus of a mammogram. Instead, the targeted purpose of a mammogram is to provide a thorough examination of breast health, making it an essential preventive measure in women's health care.
