In some men with breast cancer, the cancer cells have too much of a growth-promoting protein known as HER2/neu (or just HER2) on their surface. Breast cancers with too much of this protein are called HER2 positive.

They tend to grow and spread more aggressively without special treatment. A number of drugs have been developed that target this protein. As with many of the other treatments for breast cancer, studies of these drugs included few, if any men, so using them in men is based on how well they work in women.
