Scientists have identified a key mechanism that allows small cell lung cancer (SCLC) to return after initial treatment. The research reveals that certain cancer cells can enter a dormant, therapy-resistant state, evading chemotherapy and later reawakening to cause relapse. This process involves specific genetic and cellular pathways that enable the cells to survive. The findings, based on laboratory models and patient data, provide a new understanding of SCLC recurrence and point to potential therapeutic targets to prevent it. The full study offers deeper insights into these resilient cancer cells. Read the full article at https://www.sciencedaily.com/releases/2026/03/260325005917.htm
