Whether you are directly affected by breast cancer, or you just want to find out more, we have put together a range of resources to support you.
Breast cancer is when abnormal cells in the breast begin to grow and divide in an uncontrolled way and eventually form a growth (tumour).
Breast cancer most commonly starts in the cells that line the milk ducts of the breast. It is the most common cancer in the UK. It mainly affects women, but men can get it too.
Symptoms of breast cancer in women may include:
It's important to check your breasts regularly so you know what's normal for you. This makes it easier to notice any changes in the size, look or feel of your breasts.

If breast cancer spreads to other parts of the body it's called secondary breast cancer.
The symptoms depend on which part of the body the cancer has spread to. It can spread anywhere, but it most commonly affects the bones, liver, lungs or brain.

NHS breast screening uses X-rays, called mammograms, to look for cancers that are too small to see or feel. Anyone registered with a GP as female will be invited for NHS breast screening every 3 years between the ages of 50 and 71. You'll get a letter in the post inviting you. You need to be registered with a GP surgery to be invited for breast screening.
You'll automatically get your first invite for breast screening between the ages of 50 and 53. Then you'll be invited every 3 years until you turn 71.
If you're a trans man, trans woman or are non-binary you may be invited automatically, or you may need to talk to your GP surgery or call the local breast screening service to ask for an appointment.
