Deep dives
Understanding Small Cell Lung Cancer
Small cell lung cancer (SCLC) accounts for approximately 13% of lung cancer cases in the U.S., with significant geographic variation influenced mainly by smoking rates. Regions with higher tobacco usage report higher incidences, while areas with lower smoking rates may see more cases due to EGFR mutations. Historically, SCLC was predominantly seen in smokers, but recent studies indicate that nearly 20% of current patients may not have a smoking history, suggesting an evolution in its underlying biology. This shift raises questions about potential new environmental risk factors, emphasizing the importance of continued research and public health awareness.
