Evaluation of palpable breast masses

Area of Science:

• Oncology
• Radiology
• Pathology

Background:

• Palpable breast masses are frequent, often benign, necessitating efficient evaluation to exclude malignancy.
• Accurate diagnosis requires a combination of clinical breast examination, imaging, and tissue sampling.

Purpose of the Study:

• To outline the diagnostic approaches for palpable breast masses.
• To compare the utility and limitations of various diagnostic modalities.

Main Methods:

• Review of diagnostic techniques including clinical breast examination, mammography, ultrasonography, fine-needle aspiration (FNA), and core-needle biopsy (CNB).
• Discussion of the role of each method in differentiating benign from malignant lesions based on patient age and mass characteristics.

Main Results:

• Fine-needle aspiration is a rapid, cost-effective method for differentiating solid and cystic masses, requiring physician expertise.
• Mammography is effective for screening in older women but less sensitive in younger women. Ultrasonography aids in identifying cystic masses and guiding biopsies.
• Core-needle biopsy provides histologic diagnosis, enabling hormone-receptor testing and distinguishing in situ from invasive disease, though it is more invasive and requires imaging guidance.

Conclusions:

• The choice of diagnostic evaluation for palpable breast masses depends on patient age, clinical findings, and physician experience.
• A multimodal approach integrating clinical assessment, imaging, and tissue sampling ensures comprehensive and accurate diagnosis of breast lesions.
