Breast cancer in men: what everyone should know

Breast cancer is overwhelmingly a women's disease, which is exactly why men miss it. Men have breast tissue, it can develop cancer, and because nobody tells them to look, they often arrive at the doctor later than women do.

This article is general health information, not medical advice. Talk to a healthcare professional about your own situation.

How common it is

Roughly one in every hundred breast cancers in the United States is diagnosed in a man, a few thousand cases a year. Lifetime risk for a man is under one percent, low but not zero, and higher with a family history or certain gene mutations.

The signs are the same

  • A painless lump or thickening in the breast, usually behind the nipple.
  • Changes to the skin: dimpling, puckering, redness or scaling.
  • A nipple that turns inward, or discharge.
  • Swelling in the lymph nodes under the arm.

Risk factors

Age, most diagnoses come after 60. A family history of breast cancer in men or women. Inherited mutations such as BRCA2. Conditions that raise estrogen levels, including some liver diseases and Klinefelter syndrome. Past chest radiation.

Why men delay

Surveys consistently find men see doctors less often and wait longer with symptoms, partly because they do not know male breast cancer exists. Many go only when a partner or relative insists. Treatment is the same as for women and works as well when caught early; the delay is the problem.

How to bring it up

  • Say it plainly: men get breast cancer, and a lump behind the nipple needs a doctor.
  • Put it in the family history conversation. See why family history matters.
  • Offer to go with him. Company lowers the barrier more than facts do.

Frequently asked questions

Can men get mammograms?

Yes. If a lump is found, a doctor may order a mammogram, ultrasound and biopsy, the same as for women.

Is male breast cancer more dangerous?

Not inherently. Outcomes are worse mainly because it is found later.
