E)Hormone X is secreted in unregulated fashion by a tumor growing in a tissue that does not normally secrete hormone X.

Question

Quizplus · Accepted Answer

Secondary hypersecretion occurs when a condition or factor external to the gland that normally secretes a hormone causes that gland to secrete more of its hormone. In option A, a tumor secretes hormone Y, which then stimulates the gland that secretes hormone X, leading to increased secretion of hormone X. This is a classic example of secondary hypersecretion because the overproduction of hormone X is indirectly caused by the action of hormone Y from the tumor.
