Cancer genetics referrals

NHS referrals

We accept referrals for patients of The Royal Marsden and for their relatives who:

  • Have a personal or family history of cancer suggestive of an inherited genetic predisposition or
  • Have a known gene mutation in the family

We are commissioned to accept GP referrals for patients registered at The Royal Marsden or their relatives. 

Referrals for relatives of patients registered at The Royal Marsden should include identifying details of the patient under the care of The Royal Marsden so the referral is not rejected.

GP referrals for patients that do not meet our referral criteria should be sent to their local regional genetics service.

How to make a referral to the Cancer Genetics unit

GP referrals that meet our referral criteria should be made using the electronic referral system (eRS) to the RMH London and Sutton Cancer Genetics Referral Assessment Service located under the Genetics Speciality.

Clinic locations

Clinics are held at The Royal Marsden’s Chelsea and Sutton hospitals. Where appropriate some patients may also be offered telephone and video consultations.

Family History Questionnaires

All new patients will be sent a family history questionnaire. We ask that they complete this to the best of their ability, although we understand it may not be possible to know all the details.

The questionnaire is used to draw the family tree. This information is used as part of the risk assessment process. It may be necessary to verify the family history of cancer to assess the risk accurately and as part of that process, patients may be asked to obtain copies of their relatives' death certificates.
