Male Breast Cancer - Treatment

Treatment

Treatment largely follows patterns that have been set for the management of postmenopausal breast cancer. The initial treatment is surgical and consists of a modified radical mastectomy with axillary dissection or lumpectomy and radiation therapy with similar treatment results as in women. Also, mastectomy with sentinel lymph node biopsy is a treatment option. In men with node-negative tumors, adjuvant therapy is applied under the same considerations as in women with node-negative breast cancer. Similarly, with node-positive tumors, men increase survival using the same adjuvants as affected women, namely both chemotherapy plus tamoxifen and other hormonal therapy. There are no controlled studies in men comparing adjuvant options. In the vast majority of men with breast cancer hormone receptor studies are positive, and those situations are typically treated with hormonal therapy.

Locally recurrent disease is treated with surgical excision or radiation therapy combined with chemotherapy. Distant metastases are treated with hormonal therapy, chemotherapy, or a combination of both. Bones can be affected either by metastasis or weakened from hormonal therapy; bisphosphonates and calcitonin may be used to counterbalance this process and strengthen bones.
