From your history, it isn't clear exactly what is the cause of your bleeding one year after hysterectomy for cancer. In part it depends on the type of cancer, the stage and grade of the caner (how advanced and how aggressive the tumor is), how much bleeding there is and other factors that could be helpful in offering an answer.
One common reason could be that your ovaries were removed and/or you are in menopause and the bleeding is due to a lack of estrogen. However, to be on the safe side, it is best to see your doctor for an exam and to have any testing that might help answer the question. While there are many causes that are not serious, some are, so call and set up an appointment.
