Breast Cancer Home > Male Breast Cancer Treatment

For men whose cancer is node-positive (the cancer has spread to the lymph nodes), adjuvant therapy may include the following:
  • Chemotherapy plus tamoxifen (to block the effect of estrogen)
  • Other hormone therapy.
These treatments appear to increase survival in men as they do in women. The patient's response to hormone therapy depends on the presence of hormone receptors (proteins) in the tumor. Most breast cancers in men have these receptors.
Hormone therapy is usually recommended for male breast cancer patients, but it can have many side effects, including hot flashes and impotence (the inability to have an erection adequate for sexual intercourse).

Distant Metastases

For men with distant metastases (cancer that has spread to other parts of the body), hormone therapy, chemotherapy, or a combination of both has shown some success for male breast cancer treatment. Hormone therapy may include the following:
  • Orchiectomy (the removal of the testicles to decrease hormone production)
  • Luteinizing hormone-releasing hormone agonist with or without total androgen blockade (to decrease the production of sex hormones)
  • Tamoxifen for cancer that is estrogen-receptor positive
  • Progesterone (a female hormone)
  • Aminoglutethimide (to lessen the amount of estrogen produced).
Hormone therapies may be used in sequence (one after the other). Standard chemotherapy regimens may be used if hormone therapy does not work. Men usually respond to therapy in the same way as women who have breast cancer.

Locally Recurrent Cancer

For men with locally recurrent cancer (cancer that has come back in a limited area after treatment), treatment is usually either:
  • Surgery combined with chemotherapy
  • Radiation therapy combined with chemotherapy.
