In lung cancer surgery, it's common practice worldwide to remove a large area of the organ. The bigger the area, the worse the effect on the patient's quality of life post-surgery. Japanese doctors have developed a procedure that involves removing only a small amount of the lung. In one case, the surgery took an hour and less than a spoonful of blood was lost. The patient was discharged in 3 days and back to normal in a week. We report on the innovative method and its potential.
