Breast cancer in men

Also called Male breast cancer

Men have a small amount of breast tissue behind the nipple, and cancer can develop there. Breast cancer in men is rare and mostly affects men over 60. The most common sign is a hard, painless lump in one breast.

What it is

Risk is higher with a family history of breast cancer, inherited gene changes such as BRCA2, and conditions that raise oestrogen levels.

Treatment is similar to breast cancer in women: usually surgery, sometimes with radiotherapy, hormone therapy or chemotherapy. Genetic testing may be offered.

Common signs

  • A hard, painless lump in one breast
  • A nipple that turns inwards
  • Fluid or bleeding from the nipple
  • A sore or rash around the nipple
  • Swollen glands in the armpit

How it is usually diagnosed

  • Breast examination
  • Mammogram and ultrasound
  • Biopsy

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Imaging reports
  • Biopsy and pathology reports, including hormone receptor results
  • Genetic test results
  • Treatment plans and the follow-up schedule

Questions to ask your doctor

  • What type and stage is it?
  • Should I have genetic testing, and what would it mean for my family?
  • How long will hormone treatment last?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • There are no emergency signs specific to this; a new breast lump needs a GP appointment soon
