GP's role
- Take, and keep updated, a family history (see Genetics in practice), including:
- Three generations, maternal and paternal 1° and 2° relatives (where possible).
- Cultural and ethnic background, eg gene mutations associated with breast and ovarian cancer are more common in Ashkenazi Jews.
- The primary site and age at diagnosis of any cancer (where possible). For those people who have imprecise knowledge of cancer in their relatives, death certificates are a good source of information.
- Using the family history, assess risk according to national guidelines: average or slightly above average, moderate and potentially high risk.
- If you are unsure about the significance of the family history, contact a familial cancer service for advice (see list of familial cancer services).
- Manage average/moderately increased risk patients using the management guidelines.
- Refer patients identified at potentially high risk to a familial cancer service or Genetics Services
