Mamography
A mammography is a specialized, low-dose X-ray examination designed to visualize the internal structure of the breast tissue. It is universally recognized as the gold standard for breast cancer screening, capable of detecting early structural changes or tiny calcium deposits (microcalcifications) long before they can be felt during a physical exam.
Core Types of Mammograms
- Screening Mammogram: Performed routinely on asymptomatic individuals to catch potential signs of cancer early. It typically involves taking two standard X-ray views of each breast.
- Diagnostic Mammogram: Ordered if a screening shows an abnormality, or if a person presents with symptoms like a lump, breast pain, nipple discharge, or skin dimpling. It includes more detailed, targeted angles and magnified views.
- 3D Mammography (Tomosynthesis): An advanced technique that captures multiple X-ray slices across the breast, compiling them into a detailed 3D image. This significantly improves detection rates and reduces false alarms, especially in dense breast tissue.
What to Expect During the Procedure
During the exam, a technologist positions the breast on a specialized imaging plate. A plastic compression paddle then gently presses down on the breast tissue for a few seconds. While this compression can cause brief discomfort or pressure, it is absolutely necessary to flatten the tissue, prevent blurring from movement, and reduce the radiation dose required for a clear image.
Essential Preparation Tips
To ensure the highest accuracy, patients are advised to avoid wearing deodorants, antiperspirants, powders, or lotions under the arms or on the breasts on the day of the exam. These products often contain metallic ingredients that can show up as white spots on the X-ray, potentially mimicking abnormalities. Scheduling the test a week after your menstrual period can also help minimize breast tenderness.
