Breast cancer in men

man talking about breast cancer

Breast cancer in men is rare.

Around 390 men are diagnosed each year in the UK (compared to nearly 62,000 women). Most men who get breast cancer are over 60, although younger men can be affected.


Symptoms of breast cancer in men include:

  • a lump, often painless. This is the most common symptom. It’s usually near the centre, close to the nipple, because most of the breast tissue in men is beneath the nipple. But lumps can also occur away from the nipple
  • nipple discharge, often blood-stained
  • a tender or drawn in (inverted) nipple
  • ulceration or swelling of the chest area.

Occasionally, the lymph nodes (glands) under the arm may also be swollen.

The sooner breast cancer is diagnosed and treated, the better the outcome may be, so it’s important to get any symptoms checked out as quickly as possible.

Breast tissue in men

Many people don’t know that men can get breast cancer because they don’t think of men as having breasts. In fact, both men and women have breast tissue, although men have much smaller amounts than women. 

Men’s breast tissue can also become enlarged because of a benign (not cancer) condition called gynaecomastia.

What causes breast cancer in men?

The exact causes of breast cancer in men are not fully understood, but certain factors may increase the risk. These are called risk factors.

Finding information about men with breast cancer

Because breast cancer in men is rare, less is known about the experiences of men with breast cancer and most of the available information about breast cancer is aimed at women. It also means that most of the research into breast cancer and its treatments has been carried out in women.

While much of the information on our website is relevant to men with breast cancer, some of it addresses topics that will only affect women.

Our Men with breast cancer resource pack contains information about diagnosis, treatment and beyond that’s aimed specifically at men. It also contains quotes from men who’ve had breast cancer.
