Cancer Research UK – November 25, 2022
A group of researchers at University College London (UCL) were faced with a problem.
There was evidence that people who have never smoked were facing delays in being diagnosed with lung cancer, but it wasn’t clear how their experiences differed from those of smokers.
As a starting point, they set out to review the research that was already out there to date.
Over the course of a year, they analysed seven quantitative and three qualitative studies about people’s experiences in relation to symptom awareness, help‐seeking, and the lung cancer diagnostic pathway, comparing people with and without a history of smoking.
This wasn’t just an exercise in finding out what we know. Crucially, this review highlighted what we didn’t know to lay the groundwork for more research into lung cancer in people who have never smoked.
And one of their main findings was that there was a lack of evidence about why there were delays in diagnosis for people who have never smoked. The research indicated that people who have never smoked had a different experience to current and former smokers in getting a diagnosis, but the reasons why were still unclear.
The team, who were part of the group that performed the review, followed up on this review with another study, this time interviewing people with lung cancer to figure out similarities and differences in help-seeking behaviour depending on smoking status.
This is the first time people who have never smoked have been compared directly with current and former smokers with regards to help seeking and experiences in primary care, primary care being, for the most part, their GP.
