I had a total hysterectomy 25 years ago and now I am experiencing some bleeding. What could this mean?

If you had the uterus removed 25 years ago, the bleeding won't come from the uterus, but from other sources, like the bladder or the vagina. Any unexpected bleeding should be medically investigated, particularly since you're old. Many cancerous tumors begin with bleeding. Call your doctor right away.

Get to a doctor immediately.
