Quick facts 

  • Breast cancer is the most common cancer in women in the UK.
  • A breast lump is often the first symptom of breast cancer.
  • Breast cancer can affect men. We have a separate guide for men with breast canceropens the desktop site.
  • Treatment for breast cancer may include a combination of surgery, radiotherapy, chemotherapy, drugs to block hormones or their effects on cancer cells (hormonal therapies), and a drug called Herceptin® (trastuzumab).
  • The type of treatment you have will depend on many factors, including the size of the tumour and whether you have had your menopause.

This information is about primary breast cancer (stages 1-3). We also have information on breast cancer that has spread to other parts of the body or come back after treatment (secondary breast canceropens the desktop site).

We have more information on this topic on our desktop site.
