progesterone receptor test

Pronunciation: (proh-JES-teh-rone reh-SEP-ter test)

A lab test to find out if cancer cells have progesterone receptors (proteins to which the hormone progesterone will bind). If the cells have progesterone receptors, they may need progesterone to grow, and this can affect how the cancer is treated.
