First before I ask my question I cannot believe I found this site again. A few years ago it was like it fell off the face of the Earth. My sister or I could not even find away to order Natpro. We gave up trying and thought Natpro was out of business. Maybe someone could explain. Now as for my concern.My sister 58 yrs old has been diagnosed with endometrial cancer that has metastasized to the lungs. She is trying the natural route for cure. Should she be on progesterone?
