what is the average lifespan of someone with lung cancer who does not get treatment

by Prof. Trever Lind Published 2 years ago Updated 2 years ago

If left untreated, people with non-small cell lung cancer, the most common form of the disease, might live anywhere five to 12 months, depending on the stage. In contrast, people with small cell lung cancer generally survive three to 15 months without treatment (based on the stage).
