Book mammograms when eligible

Screening mammograms can find breast cancer before symptoms and reduce the chance of dying from it.

Why it matters

Mammography can find cancers while treatment is more effective. The USPSTF changed its guidance in 2024 to screening every other year from ages 40 to 74. Screening can also cause false alarms and detect cancers that would never have caused harm, so benefits and harms both matter.

How to do it

  1. Check when your next screening mammogram is due.
  2. Use your local programme: the US schedule is every 2 years at ages 40 to 74, the NHS invites every 3 years from 50 to 71, and the EU recommends ages 50 to 69.
  3. Tell the service about previous breast cancer, chest radiation or a strong family history.
  4. Complete any requested follow-up imaging or biopsy.

A new lump, nipple change or other symptom needs prompt assessment even after a normal mammogram. Higher risk and age 75 or older require an individualized plan. Trans and non-binary people may also be eligible depending on anatomy and hormone treatment; ask your GP or screening service.

Do it

Pick the time you have. Anything beats nothing.

Start with the time you have

1 minute

Choose one thing to tell the screening service when booking: an implant, access need, previous breast cancer or family history.

In real life

  • If the offered mammogram time does not work, contact the service to change it.
  • Tell the service about breast implants or mobility needs so it can plan the appointment.

Watch out for

  • Common mistakeA new lump needs assessment even after a normal mammogram, so contact a clinician rather than waiting for screening.
  • Common mistakeA missed appointment is not a reason to give up, so contact the programme to rebook.
