Male Breast Diseases

Abstract

• No cause is found in 25 % of patients who develop gynaecomastia. • After persistent pubertal gynaecomastia, medication use and substance use are the most common causes of non-physiologic gynaecomastia. • In adult males gynaecomastia is often multifactorial, due to increased aromatisation of testosterone to oestradiol and the gradual decrease of testosterone production. • In men symptomatic or at high risk, the presence of gynaecomastia or obesity may mask early symptoms of MBC. • Core biopsy should be performed following imaging in those patients with uncertain or suspicious clinical or radiological findings. FNA is not recommended.

Future directions. Treatment for men with BC is the same as for women with the disease, but, according to new research, differences have been found that may change the way men will be treated in the future. Superficially, both genders appeared similar, but using more detailed analysis, subtle variations were observed specifically in relation to the hormone receptors, which influence the growth of most BCs. These findings highlight the need to understand more about how anti-hormone treatments can be optimised.
