Breast Cancer in Males: What to Know
Males have a small amount of breast tissue and can get breast cancer. Breast cancer is a malignant growth of tissue (tumor) in the breast.
Unlike benign tumors, which aren't cancer, malignant tumors are cancer and can spread to other parts of the body.
What are the causes?
The cause of male breast cancer is not known.
What increases the risk?
These factors may make you more likely to develop breast cancer.
Age. Most cases of male breast cancer occur in people who are in their 60s or 70s.
Having a family history of breast cancer, or having the BRCA1 and BRCA2 genes.

Other risk factors include:
What are the signs or symptoms?
Symptoms of breast cancer include:
A painless lump in the breast.
Changes in the size or shape of your breast.
Breast skin changes, such as puckering or dimpling that looks like an orange peel.
Sores on the skin.
Nipple abnormalities, such as scaling, crustiness, redness, or pulling in.
Nipple discharge that is bloody or clear.
How is this diagnosed?
Breast cancer may be diagnosed by:
Your medical history.
A physical exam. Your health care provider will feel the tissue around your breast and under your arms.
Taking a sample of any nipple discharge. The sample will be examined under a microscope.
Imaging tests, such as breast X-rays (mammogram), ultrasound, or MRI.
Taking a tissue sample from the breast. The sample will be examined to look for cancer cells.
Taking a sample from the lymph nodes near the affected breast.
Your cancer will be staged after diagnosis to determine the size, location, and if it has spread in your body. This will help your cancer care team decide on a treatment that will work best for you. You may need to have more tests to determine the stage of your cancer.
How is this treated?
Depending on the type and stage, breast cancer may be treated with one or more of these therapies:
- Surgery. The goal is to remove as much of the cancer as possible.
This is done with a procedure to remove the whole breast and nipple. Some normal tissue surrounding this area may also be removed.
This surgery may also involve removing lymph nodes in the area to be checked for cancer cells.
Radiation therapy, which uses high-energy rays to kill cancer cells.
Chemotherapy, which is the use of medicines to kill cancer cells.
Hormone therapy, which involves taking medicine to adjust the hormone levels in your body. You may take medicine to decrease your estrogen levels. This can help stop cancer cells from growing.
- Targeted therapy. There are medicines that are used to block the growth and the spread of cancer cells.
Immunotherapy, which is the use of medicines to boost the immune system to recognize and destroy cancer cells more effectively.
A combination of surgery, radiation, chemotherapy, or hormone therapy may be needed to treat breast cancer.
