Read our blog, Men Get Breast Cancer Too.
Breast cancer can occur in men. In 2020, it’s estimated 2,620 new cases of breast cancer will be diagnosed in men in the U.S. .
Men can also be diagnosed with benign (not cancer) breast conditions.

Prognosis for breast cancer in men is similar to prognosis in women of the same age and cancer stage [199-201].
However, men are often diagnosed at a later stage than women . Men may be less likely than women to report any warning signs or symptoms of breast cancer. This may lead to a delay in diagnosis .
The 5-year relative survival rate for men with breast cancer is 84 percent . This means men with breast cancer are, on average, 84 percent as likely to live 5 years beyond their diagnosis as men in the general population.
The 10-year relative survival rate for men with breast cancer is 71 percent .
Survival rates are averages and vary depending on each man’s diagnosis and treatment.
Most breast cancers in men begin in the milk ducts of the breast (invasive ductal carcinomas).
Fewer than 2 percent of breast cancers in men begin in the lobules of the breast (invasive lobular carcinoma) .
Men can also be diagnosed with ductal carcinoma in situ (a non-invasive breast cancer), inflammatory breast cancer or Paget disease of the breast (Paget disease of the nipple) .
Men tend to be diagnosed with breast cancers that are hormone receptor-positive and HER2-negative [199,206].
Learn about the anatomy of the breast.
All men diagnosed with breast cancer should have genetic testing .
There are special cancer screening recommendations for men with a BRCA2 or BRCA1 gene mutation.
For men with metastatic breast cancer, knowing you have a BRCA1 or BRCA2 gene mutation can help guide treatment.
Learn more about genetic testing and genetic counseling.
Treatment for breast cancer in men is similar to treatment for women. It includes some combination of surgery, radiation therapy, hormone therapy, chemotherapy and HER2-targeted therapy.
The main treatment for breast cancer in men is surgery to remove the tumor. This is usually a mastectomy because of the small size of a male breast. Some men may choose to have breast reconstruction.
Some men who have mastectomy may also have radiation therapy after surgery, depending on the stage of the breast cancer.
Sometimes, breast surgery in men is a lumpectomy (also called breast conserving surgery). Men who have a lumpectomy usually have radiation therapy after surgery.
Most breast cancers in men are hormone receptor-positive.
For men with hormone receptor-positive breast cancers, the hormone therapy drug tamoxifen is usually the first drug therapy used.
Tamoxifen is a pill taken every day for 5-10 years.
In men, possible side effects of tamoxifen include [87-89]:
Some men find it hard to complete the long period of hormone therapy treatment. However, to get the most benefit, you need to take the full course of treatment prescribed by your health care provider. Men who complete the full course have higher rates of survival than men who don’t .
If you have any side effects with tamoxifen, talk with your provider.
If you have trouble remembering to take your medicine, a daily pillbox or setting an alarm on your watch or mobile device (you may be able to download an app) may help .
However, you don't need to panic if you miss a day or two.

For men with hormone receptor-negative breast cancer, chemotherapy is usually the first drug therapy used.
For men with hormone receptor-positive breast cancer, chemotherapy may be given before tamoxifen therapy, depending on the cancer stage.
Men with HER2-positive breast cancers may be treated with HER2-targeted therapies (such as trastuzumab (Herceptin)) plus chemotherapy with a taxane.
Research is ongoing to improve all areas of treatment for breast cancer.
New therapies are being studied in clinical trials. The results of these studies will decide whether these therapies become part of standard care.
After discussing the benefits and risks with your health care provider, we encourage you to consider joining a clinical trial.

Social support is important after a breast cancer diagnosis.
Men with breast cancer may feel isolated. Support groups for breast cancer may only have female members, so joining a support group for men with any type of cancer may be more helpful.
Susan G. Komen®'s free, 6-week telephone support groups for men with breast cancer provide a safe place for men to discuss the challenges of breast cancer, get information and exchange support. To learn more, call the Komen Breast Care Helpline at 1-877 GO KOMEN (1-877-465-6636) or email firstname.lastname@example.org.
Other organizations offer online support groups and other support resources for men with breast cancer. For example, the American Cancer Society’s Cancer Survivors Network has an online support for men with breast cancer.
