Breast cancer is the most common type of cancer in the UK. Most women diagnosed with breast cancer are over the age of 50, but younger women can also get breast cancer.
About 1 in 8 women are diagnosed with breast cancer during their lifetime. There's a good chance of recovery if it's detected at an early stage.
For this reason, it's vital that women check their breasts regularly for any changes and always have any changes examined by a GP.
Breast cancer screening
However, you should be aware that a mammogram might fail to detect some breast cancers.
It might also increase your chances of having extra tests and interventions, including surgery, even if you're not affected by breast cancer.
Women with a higher-than-average risk of developing breast cancer may be offered screening and genetic testing for the condition.
As the risk of breast cancer increases with age, all women who are 50 to 70 years old are invited for breast cancer screening every 3 years.
Women over the age of 70 are also entitled to screening and can arrange an appointment through their GP or local screening unit.
The NHS is in the process of extending the programme as a trial, offering screening to some women aged 47 to 73.
