 Recent advances in technology has helped us to improve the outcome of lung cancer. Previously, the outcome of lung cancer was very miserable, about 5-10% of survival among all the lung cancer patients. Now, with the advances in surgical techniques, we can do surgery to remove the lobe or the entire lung by means of open surgery or a robotic or a thoracoscopic surgery, a minimal access surgery as well. The advances in chemotherapy also has come in a long way. The biomarkers and the targeted therapy and immunotherapy has improved the survival of stage 4 lung cancers to 30% 5-year survival where it was less than 5% 5-year survival some years back.
