Escalate
Airway compromise, superior vena cava obstruction, spinal cord compression, pathological fracture, uncontrolled bleeding, bowel obstruction, severe hypercalcaemia, neutropenic sepsis or rapidly worsening neurological deficit requires same-day acute assessment. Stabilisation and urgent imaging or specialist treatment must not wait for a routine suspected-cancer appointment.
Synopsis
Recognise symptom patterns that may represent cancer, identify emergencies, use current NICE referral routes and direct-access tests, and safety-net patients whose initial probability remains uncertain.
Cancer recognition combines symptom, examination, age, duration, risk factors and trajectory; no single red flag is sufficiently sensitive to exclude disease when absent.
Use the current NICE NG12 site-based or symptom-based recommendations and local referral form rather than memorised historical thresholds.
An urgent suspected-cancer referral means cancer must be excluded promptly; it does not mean that cancer is the most likely diagnosis.
Key red flags
Progressive obstructive symptom
Increasing dysphagia, jaundice, bowel obstruction, stridor or urinary obstruction suggests structural disease and may need acute rather than outpatient care.
Investigation priorities
01
Focused history and examinationFirst step
Localise the likely organ system and identify emergency complications.
Management branches
EmergencyStabilise a cancer complication
The presentation includes airway, neurological, haemorrhagic, obstructive or metabolic instability.
Use ABCDE assessment, treat immediate physiology and contact the relevant acute oncology, surgical, critical-care or site team.
Obtain urgent targeted imaging and blood tests without allowing the absence of a known cancer diagnosis to delay emergency treatment.
National guidance is shown before implementation-dependent detail. Typical adult dose examples remain subject to patient factors, contraindications and the live BNF or specialist protocol. Source check completed 27 Aug 2026; clinical approval remains outstanding.
