The service includes:

  • an appointment to discuss family history of cancer
  • a family tree and explanation of the risks
  • information about symptom awareness, screening and lifestyle advice
  • referral for enhanced breast or bowel screening, if needed 
  • a discussion about medicine to prevent cancer (chemoprevention), if needed
  • referral to the genetics clinic to discuss further options, if needed

Who can use the service?

The service is for anyone with a personal or family history of breast, ovarian, and bowel cancer, or bowel polyps.

If you have a family history of breast or ovarian cancer

You can refer yourself to the service if you live in or are registered with a GP in:

  • Bromley
  • Lambeth
  • Lewisham
  • Southwark

People living outside of these boroughs will need a GP referral.

If you have a family history of bowel cancer or polyps

This service is available for anyone referred by their GP.

If you experience any breast changes, bowel symptoms or have concerns about your health, please contact your GP.

How do I access the service (self-refer)?

You will not have a physical examination or a blood test at the clinic. The appointment will last about 30 minutes.
