NEW YORK, Nov 21, (Agencies): In the United States, lung cancer claims more lives each year than the combined toll of colon, breast, and prostate cancers. Advances in treatments offer greater success when lung cancer is detected in its early stages. Traditionally, screening guidelines have primarily targeted cigarette smokers. Dr. Robert Smith, American Cancer Society senior vice president of Early Cancer Detection and Science, emphasizes the need to consider additional risk factors for lung cancer.

The recently issued guidelines from the American Cancer Society now recommend annual low-dose CT scans for individuals aged 50-80 with a 20-pack-year history or more. A pack-year history encompasses various smoking scenarios, such as smoking a pack a day for 20 years, regardless of how long ago this occurred. Dr. William Dahut, American Cancer Society chief scientific officer, notes that these expanded guidelines could make approximately 5 million more people eligible for screening. The estimated impact includes a 21% increase in prevented lung cancer deaths and a 19% gain in life years compared to the current recommendations.

However, adherence to these guidelines doesn't guarantee insurance coverage for the screening. Individuals are advised to consult with their primary care provider to determine eligibility and assess the necessity of screening. Dr. Dahut stresses the importance of spreading awareness, especially for those who may not identify as current smokers but have a significant smoking history. Advocacy for oneself and discussions with primary care doctors are essential steps to explore screening opportunities within the healthcare system.
