A 50-year-old male asked:
If small cell lung cancer grows so quickly, why is the primary often difficult to visualise on ct with contrast? is the primary slow growing? thanks.

Observation: It is not clear why small cell lung cancer can have larger secondaries than the primary lesion. But it is a common observation and metastatic lesions/secondaries may be the first manifestation of this cancer and the primary may be difficult to visualize. It is not due to the slow growth rate of the tumor.
