Why 3 symptoms, 3 visits or 3 weeks?
This message for professionals has been chosen based on the evidence we have. We know that some symptoms of cancer are more obvious than others and so whilst, for some, cancer will be considered very quickly, for others it may take longer.
In the CCD study, 50% of solid tumours were diagnosed within 3 weeks of seeing a healthcare professional, and leukaemias often much more quickly than that.
We want to shorten the time for the other 50%. Ensuring healthcare professionals are considering cancer in children at the 3-week mark if symptoms are progressive and unexplained will help us reach our target of diagnosing 75% of children and teenagers within 3 weeks from first contact with a healthcare professional.
The other part of this message highlights picking up the phone. Referrals for suspected childhood cancers differ from adult cancer pathways, but this is not well known and many of our children and teenagers are still being referred using urgent suspected cancer pathways.
Childhood cancer grows much more quickly than adult cancers, and so if cancer is suspected, our guideline advises picking up the phone and discussing the case with your local on-call paediatrician. They will be able to advise where best to send the child or teenager depending on their story. This may well be in a rapid access clinic or similar, or straight to paediatrics the same day if there is strong suspicion.
