Mammography

Mammography is a specialized X-ray imaging technique of the breast used to detect and evaluate breast abnormalities at an early stage, often before they can be felt through physical examination. It plays a crucial role in screening for breast cancer and in diagnosing breast conditions such as lumps, pain, or nipple discharge. By producing high-resolution images of breast tissue, mammography can reveal microcalcifications, cysts, tumors, and structural distortions that may suggest benign or malignant disease.

Clinical Applications

  • Early detection of breast cancer (reduces mortality).

  • Evaluation of breast lumps, cysts, or calcifications.

  • Monitoring high-risk women (family history, genetic mutations like BRCA1/2).

  • Follow-up after breast surgery or cancer treatment.

  • Guidance for biopsies (stereotactic mammography).

Advantages

  • Gold-standard for early breast cancer detection.

  • Detects abnormalities before they are clinically palpable.

  • Widely available and relatively low-cost.

  • Digital and 3D mammography provide higher accuracy, especially in dense breasts.

Limitations & Risks

  • Radiation exposure (very low, but cumulative with repeated scans).

  • Less sensitive in dense breast tissue (common in younger women).

  • Slight discomfort due to breast compression.
