Diagnosing Gynecomastia: A Step-by-Step Guide
Published: Sep 10, 2023
Identifying gynecomastia correctly is essential to distinguish it from other conditions. Here’s how it’s done.
Contents
Physical Examination
Diagnosis begins with a physical exam, feeling for a rubbery mass under the nipple. This mass is typically bilateral and tender, marking the presence of gynecomastia. The examination helps differentiate it from other conditions like pseudogynecomastia.
Imaging Techniques
Imaging is recommended if there is suspicion of breast cancer. Mammography and ultrasound are the primary tools used, with mammography being more sensitive for detecting malignancies.

Understanding the Differential Diagnosis
It’s crucial to differentiate gynecomastia from other breast masses. Breast cancer, for example, is usually unilateral and firm, unlike the bilateral and tender mass of gynecomastia.
