Symptom perceptions and help-seeking behaviour prior to lung and colorectal cancer diagnoses: a qualitative study.

ABSTRACT

BACKGROUND: Lung and colorectal cancer are common and have high UK mortality rates. Early diagnosis is important in reducing cancer mortality, but the literature on lung and colorectal cancers suggests many people wait for a considerable time before presenting symptoms. OBJECTIVE: To gain in-depth understanding of patients' interpretations of symptoms of lung and colorectal cancer prior to diagnosis, and to explore processes leading to help-seeking. METHODS: Semi-structured interviews were conducted with patients diagnosed with lung (N=9) or colorectal (N=20) cancer within the previous 12 months. Patients were asked about symptoms experienced in the period preceding diagnosis, their interpretations of symptoms, and decision making for help-seeking. Thematic analysis was conducted and comparisons drawn within and across the patient groups. RESULTS: Patients were proactive and rational in addressing symptoms; many developed alternative, non-cancer explanations based on their knowledge and experience. Discussions with important others frequently provided the impetus to consult, but paradoxically others often initially reinforced alternative explanations. Fear and denial did not emerge as barriers to help-seeking, but help-seeking was triggered when patients' alternative explanations could no longer be maintained, for instance due to persistence or progression of symptoms. CONCLUSION: Patients' reasoning, decision making and interpersonal interactions prior to diagnosis were complex. Prompting patients for additional detail on symptoms within consultations could elicit critical contextual information to aid referral decisions. Findings also have implications for the design of public health campaigns.
