Although most women have gone through menopause by age 54, you are still in the normal window. The mean age in the United States is 51. It will likely happen in the next year. Menstrual patterns like yours are also in the normal range of what happens at 54.
Having fibroids that grow can be normal or can represent a problem. It isn't usually cancer but it can be. If the CT and ultrasound seem normal, then the chances of cancer are pretty slim. Your doctor can do an office biopsy of the uterine lining to be sure there is no cancer of the lining but that does not test the fibroids. However, a normal looking CT/ultrasound means it is probably normal.
Some doctors will put an IUD into the uterus that contains progesterone such as Mireena. Sometimes that stops the bleeding or controls it until menopause comes. Others do endometrial ablation (actually a procedure where the inside lining of the uterus is heated so it can't bleed any more). Others suggest doing the hysterectomy since you are uncomfortable and it sounds like the uterus is pressing on your bladder and other internal organs. This isn't something that is going to make something bad happen, but it is unpleasant. But just because you haven't had menopause yet isn't a reason to panic. Make sure to take iron tablets and a multivitamin to be sure you don't get anemic from the extra bleeding.
