Lung cancer: a potential role for dentists.

Lung cancer is the leading cause of death from cancer worldwide and causes more deaths than breast, colorectal and cervical cancers combined. The five-year survival rate for lung cancer in the UK is approximately 15%. Over many years, lung cancer has failed to attract the attention and resources given to other cancers; it has also been stigmatised by a culture of blame, attributable to the sufferer because of smoking. Anyone can develop lung cancer, and between 15% and 20% of people with this diagnosis have never smoked. Many patients with lung cancer are diagnosed at late stages; therefore, early detection is pivotal to improving their survival. Dentists and their teams could potentially play a role in the public perception, prevention and detection of lung cancer.
