GPs should consider a more overt discussion with patients when referring them for further investigation of symptoms which may indicate cancer, according to a paper published in the British Journal of General Practice.

O'Dowd et al found that patients that die early from lung cancer are interacting with primary care pre-diagnosis, suggesting potentially missed opportunities to identify them earlier


CANDID Qualitative Evaluation (download on the right): McLachlan et al findings suggest that prompting patients for further detail on symptoms within consultations may provide critical contextual information to aid referral decisions. The model of symptom interpretation and help-seeking developed from this study could be used by primary care practitioners to facilitate this process. The results also have implications for public health campaigns for lung and colorectal cancers.

Cancer Research UK provide the following advice to Health Professionals on their  'Be Clear on Cancer' website:

"Make it part of your day-to-day conversations. Whether you are working in a GP practice or pharmacy, training frontline workers, delivering health advice/information, working with hard to reach groups in the community, or chatting to colleagues, make every contact count. Talking may prompt someone to make an appointment, or to open up about any concerns or a symptom they didn’t think was serious. We need to encourage people to talk openly about cancer. This campaign gives us all the chance to do that."
