Expanded Lung Cancer Screening Guidelines Increase Eligibility and Urgency for Testing

The American Cancer Society has updated its lung cancer screening guidelines, recommending yearly low-dose CT scans for most individuals aged 50 to 80 with a 20-year or greater pack-year history, regardless of current smoking status. Lung cancer is the third most common cancer in the US, with smoking being the primary risk factor. There are two main types of lung cancer: small-cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). Early detection is crucial, as localized cancers have higher survival rates. Treatment options include radiation, chemotherapy, surgery, and immunotherapy. To reduce the risk of lung cancer, quitting smoking is essential, and individuals should also minimize exposure to second-hand smoke and environmental hazards.
