Yes - but very rare: B"sd do you mean small cell lung cancer? Elevated cortisol can be related to stress or to pituitary, adrenal or rarely, ectopic ACTH as in lung cancer. The best screening test is late night salivary cortisol (or a blood cortisol - but this is inconvenient in late PM). Normal cortisol is highest in the AM and close to zero late in the day. This is complicated. Glad to discuss.
