What is breast cancer?

Breast cancer is the name for cancers that start in the breast. It is the most common cancer in the UK.

Over 50,000 women are diagnosed with breast cancer each year in the UK, including around 4,600 in Scotland. Breast cancer survival is improving, yet there are still nearly 1,000 women who die of breast cancer every month in the UK.

Breast cancer in men is rare, with around 350 men diagnosed each year in the UK. However, it’s still important that it is caught early and there are signs and symptoms that men can look out for.
