In carcinoid tumors of the lung, which feature is commonly observed?

Pulmonary carcinoid tumors are neuroendocrine in origin, meaning they often secrete peptide hormones and other bioactive substances. That secretion can produce paraneoplastic effects, such as episodic flushing, diarrhea, wheezing, or other hormone-related symptoms. Because of this hormonal activity, paraneoplastic phenomena are a commonly observed feature of these tumors, more so than the other statements. They don’t have a special predilection for younger adults, they’re not strongly linked to cigarette smoking, and the systemic carcinoid syndrome (the full suite of flushing, diarrhea, and bronchospasm) is not always present—usually it’s seen when there is substantial secretory activity or metastasis.
