A member asked:
Is it true that the primary tumor in small cell lung cancer is often occult? does this mean even a ct scan can't see it? do we only detect on spread
A doctor has provided 1 answer
At some point: in its development, every cancer is "occult" because it originates on a microscopic level. CT has a high sensitivity for detecting lung cancer, approximately 95%, so CT will detect the vast majority of lung cancers.
