Cheek Swab May Detect Lung Cancer
October 7th, 2010
Early detection is critical for improving cancer survival rates. Yet, one of the deadliest cancers in the United States, lung cancer, is notoriously difficult to detect in its early stages.
Now, researchers have developed a method to detect lung cancer by merely shining diffuse light on cells swabbed from patients’ cheeks.
In a new clinical study, the analysis technique—called partial wave spectroscopic (PWS) microscopy—was able to differentiate individuals with lung cancer from those without, even if the non-cancerous patients had been lifetime smokers or suffered from chronic obstructive pulmonary disease (COPD).
The findings released by a team of engineers and physicians from NorthShore University Health System, Northwestern University and New York University appear in print in the Oct. 15, 2010, issue of the journal Cancer Research.
