I HAVE BEEN ON ARIMADEX 1M FOR 2 MONTHS, I HAVE HAD WHAT FEELS LIKE A YEAST INFECTION AND BEEN TESTED(CULTURE) AND IT IS NOT A BACATERIA, YEAST OR STD, BUT CONTINUE TO HAVE THE ODOR AND DISCHARGE LIKE A YEAST INFECTION. THE FEMALE DOCTOR WANTS TO DO A BIOPSY ON MY VAGINA EVEN THOUGH I HAVE HAD A TOTAL HYSTERECTOMY. I AM SCARED OF HAVING CANCER AGAIN (BREAST CANCER IN MAY) BUT I KNOW I HAVE NOT HAD THIS PROBLEM BEFORE THE ARIMADEX. THE ONCOLOGIST SAYS THAT YEAST INFECTION IS NOT ONE OF THE SIDE EFFECTS. THAT IT IS NOT THE ARIMADEX
