    Male Breast Cancer Treatment (PDQ®): Treatment - Patient Information [NCI] - General Information about Male Breast Cancer

    If cancer is found, tests are done to study the cancer cells.

    Decisions about the best treatment are based on the results of these tests. The tests give information about:

    • How quickly the cancer may grow.
    • How likely it is that the cancer will spread through the body.
    • How well certain treatments might work.
    • How likely the cancer is to recur (come back).

    Tests include the following:

    • Estrogen and progesterone receptor test: A test to measure the amount of estrogen and progesterone (hormones) receptors in cancer tissue. If cancer is found in the breast, tissue from the tumor is checked in the laboratory to find out whether estrogen and progesterone could affect the way cancer grows. The test results show whether hormone therapy may stop the cancer from growing.
    • HER2 test: A test to measure the amount of HER2 in cancer tissue. HER2 is a growth factor protein that sends growth signals to cells. When cancer forms, the cells may make too much of the protein, causing more cancer cells to grow. If cancer is found in the breast, tissue from the tumor is checked in the laboratory to find out if there is too much HER2 in the cells. The test results show whether monoclonal antibody therapy may stop the cancer from growing.

    Survival for men with breast cancer is similar to survival for women with breast cancer.

    Survival for men with breast cancer is similar to that for women with breast cancer when their stage at diagnosis is the same. Breast cancer in men, however, is often diagnosed at a later stage. Cancer found at a later stage may be less likely to be cured.

    Certain factors affect prognosis (chance of recovery) and treatment options.

    The prognosis (chance of recovery) and treatment options depend on the following:

    • The stage of the cancer (whether it is in the breast only or has spread to other places in the body).
    • The type of breast cancer.
    • Estrogen-receptor and progesterone-receptor levels in the tumor tissue.
    • Whether the cancer is also found in the other breast.
    • The patient's age and general health.
