What is the life expectancy of someone with small cell lung cancer?

Small cell lung cancer (SCLC) is the less common and more aggressive form. Five-year survival rates for SCLC vary depending on the stage, but the average is about 7% survival after 5 years. Survival rates will depend on the stage of cancer and how well a person responds to treatment.

Chest pain: When a lung tumor causes tightness in the chest or presses on nerves, you may feel pain in your chest, especially when breathing deeply, coughing or laughing.
