Answer

Breast imaging, through mammography or ultrasonography, may be controversial, because gynecomastia is much more common than male breast cancer. The positive predictive value of imaging in males is 55% using mammography and 17% using ultrasonography. [4]  However, a study by Telegrafo et al in which ultrasonography was used to diagnosis and classify gynecomastia found the same results as when mammography was used, suggesting that ultrasonography can be employed as a primary imaging modality for determining the presence of gynecomastia and categorizing its shape.
