Cancer Diagnosis and Patient Pathways in Primary Care

The journey to a cancer diagnosis often begins in primary care, where patients first present with symptoms to general practitioners (GPs). This setting plays a pivotal role in the early detection of malignancies, steering patients through clinical assessment, referral decisions and initial investigative steps. Patient pathways are shaped by the nature of presenting symptoms, the timeliness of help seeking and the availability of urgent referral protocols. Variations in symptom signature, such as alarm features or non-specific complaints, influence diagnostic intervals both before and after GP consultation. Delays may occur at the patient level, through lack of symptom recognition or barriers to accessing care, at the clinician level, through misinterpretation of early signs or cognitive biases, and at the system level, through constrained referral capacity or diagnostic resources. Global strategies to enhance early detection include public awareness campaigns, safety-netting approaches in primary care and standardised cancer patient pathways that aim to reduce time to investigation and treatment. National audits of primary care diagnostic processes have begun to identify sources of delay and to benchmark performance, guiding quality-improvement initiatives. As healthcare systems grapple with rising cancer incidence, optimising the primary care component of patient pathways remains central to improving outcomes and narrowing international survival gaps.
