Acute Diagnostic Oncology Clinic (ADOC)

Offering rapid access to treatment for cancer-related emergencies

What we do

Improving time to cancer diagnosis

ADOC clinics run at both our Chelsea and Westminster and West Middlesex hospitals. The clinics provide better patient and GP experience with faster access to relevant tests to diagnose or exclude cancer in a cost-effective manner. It is a service specifically designed for GPs to refer patients with an urgent suspected cancer diagnosis, where the patient is not well enough to wait for a two-week standard referral but is well enough to attend an outpatient appointment. GPs can refer patients who have non-specific but concerning symptoms of a new cancer.  

We aim to see patients within five working days, depending on patient urgency. GPs can contact the ADOC team to discuss their patient before an appointment will be agreed. The clinic team are happy to discuss cases and provide advice and guidance by email or telephone.  

Referrals must meet criteria and include recent results. If you are unsure, the clinic team can discuss and provide advice. 

Patients must meet the criteria:

  • Over 18 years of age
  • Clinical or radiological suspicion of cancer
  • Does not meet alternative tumour-specific pathways
  • Well enough to attend an outpatient clinic
  • Aware they may have cancer

Medical emergencies should not be referred to the clinic and instead should be sent to A&E.
