I am a 64 yr old female. I had a partial hysterectomy in 1986. Only my uterus was removed. I have been going thru menopause for several years and believe I am post menopausal now. I have been having some vaginal bleed ing several months now. It's only when I go to the bathroom. Not any other time. I have chronic constipation and have had all of my adult life. The bleeding is worse when I strain to have a bowel movement. Also last March I had surgery for a kidney cancer. The cancer was cleanly removed and I still have 90% of my kidney. Can you help me?
