Hello, can an ovarian cyst cause hormonal changes in a woman? what type of cyst would do this? thanks.

Ovarian cyst? : Rarely an ovarian tumor will produce hormones in excess (neoplasm), but in general, a woman's fifth decade (40 onward) will bring excess hormone b/c the ovarian matrix (not a cyst, per se) will produce far more estrogen to ovulate as the eggs age. Heavier periods, more PMS and emotional changes will occur. Ask your gyn about low dose oral bcp's, which can reduce this phenomenon.
