Breast screening is currently offered to women aged 50 to 70 in England. You'll first be invited for screening between your 50th and 53rd birthday, although in some areas you'll be invited from the age of 47 as part of the trial extension of the programme.
You may be eligible for breast screening before the age of 50 if you have a very high risk of developing breast cancer.
If you're over the age of 70, you'll stop receiving screening invitations. You can still have screening after 70 if you want to, and can arrange an appointment by contacting your local screening unit or GP.
