New U.S. guidelines recommending low-dose computed tomography (CT) scans to screen for lung cancer in high-risk individuals are leading to earlier detection and better survival for lung cancer patients. Screening is available without a prescription for people who have smoked the equivalent of at least a pack of cigarettes per day for 30 years. The scans can uncover lung cancer in early stages, when the chances for successful treatment are the highest. Recent medical advances have also made lung cancer surgery less invasive. Robotic surgeries can often be performed through small incisions in the chest, without the need to crack open ribs. These developments mean more lung cancer patients can undergo surgery and those who do have an easier recovery.
