Mammogram
A mammogram is an X-ray imaging examination of the breast used to screen for and diagnose breast cancer. It can detect tumors or calcifications before they are felt, and is central to recommended breast cancer screening programs.
What is a mammogram?
A mammogram is a low-dose X-ray examination of the breast used to look for signs of breast cancer. It can reveal masses, distortions, and tiny calcium deposits known as calcifications, often before a lump can be felt during a physical exam.
Mammograms are performed both as routine screening for people without symptoms and as a diagnostic tool when a concern has already been identified. Newer techniques such as tomosynthesis create layered, three-dimensional images to improve detection.
Why is the mammogram important?
Early detection is one of the strongest factors in breast cancer survival, and the mammogram is the cornerstone of organized screening programs that aim to find disease at a more treatable stage. Regular screening for appropriate populations is recommended across major clinical guidelines.
Because the mammogram is so central to preventive care, access, follow-up on abnormal results, and timely scheduling all matter. Gaps in any of those steps can delay diagnosis, which is why coordination around screening and follow-up imaging is closely tracked.
