Hello girlfriends, when I was 48 I was still menstruating and PMSing (actually diagnosed PMDD). Then I got cancer. Chemo induced menopause. No periods for two years now, coinciding with my very first chemo treatment! Anyway, doctor wanted a bone density because of the sudden chemical induced cessation of periods. Insurance wouldn't pay for bone denisty until I was 65! Doctor wrote letter, insurance finally complied. Bone density came back "osteopenia." Now I take Fosamax. I am grateful to know about osteopenia and Foxamax because both my mother and grandmother have osteoporosis. I'm glad there is treatment for this generation, and generations to follow. Love and Light, Lynn
