Scientists discover why this deadly lung cancer keeps coming back

Small cell lung cancer (SCLC) is among the most aggressive types of lung cancer, with a five-year survival rate of just five percent. Although it often responds well to chemotherapy at first, that success is usually short lived. Most patients experience a relapse, followed by rapid disease progression. Because of this pattern, understanding the biology behind SCLC is critical for extending treatment benefits, preventing relapse, and improving long term outcomes.
