- Breast cancer is cancer that starts in the breast.
- It's the most common type of cancer in women in the UK.
- Anyone can get breast cancer.
- How serious breast cancer is depends on how big the cancer is, if the cancer has spread, and your general health.
- Breast screening (mammogram) can pick up breast cancer that is too small to feel or see, which may make treatment more likely to be successful.
- Sometimes breast cancer can spread to another part to the body, this is called secondary breast cancer.
There's separate information about breast cancer in men.
