Quick answers
These answers are written for patients and families trying to understand whether a missed or delayed cancer referral by a GP may justify investigation. They are general information only.
Can you claim if a GP missed cancer symptoms?
A claim may be possible if a GP failed to act on symptoms, signs, abnormal results or risk factors that should reasonably have prompted investigation or referral, and the delay made the outcome worse.
What symptoms can matter?
Cancer can present in many ways. Persistent unexplained symptoms, lumps, bleeding, weight loss, bowel changes, breast changes, abnormal blood results or repeat attendances can all be relevant depending on the clinical context.
Why NICE suspected cancer guidance matters
NICE guidance sets out symptoms and findings that may require urgent suspected cancer referral or investigation. It does not decide every legal case, but it can be important when assessing what a reasonable GP should have considered.
Why causation is often difficult
It is not enough to show that diagnosis was delayed. Expert evidence must usually consider whether earlier referral or investigation would probably have led to earlier diagnosis, different treatment, improved prognosis or avoidance of harm.
What records are needed?
Important records can include GP notes, referral history, blood tests, imaging, pathology, clinic letters, cancer pathway dates, MDT records, treatment records and complaint correspondence.
How Scott assesses these cases
Scott and his team consider the timeline from first symptoms to diagnosis, whether red flags were missed, whether referral should have happened earlier, and whether expert evidence is likely to support causation.
