Early detection of lung cancer is vital for increasing a patient’s survival rate and to prescribe the best form of treatment. Now New York researchers have developed an early detection method involving a simple cheek swab. Called partial wave spectroscopic (PWS) microscopy, this new technique involves shining diffuse light on cells from the swab. The test is able to distinguish individuals with or without lung cancer, even if the patient has been a lifelong smoker or suffers from other smoking related illnesses.
