I am sorry for your daughter.
womb cancer or uterine cancer would be very very rare in a 23 year old patient.
if biopsy of the uterus shows cancer, then the treatment and cure would be a surgery to remove the womb. this is called a hysterectomy.
usually sexual abuse during childhood doesn't cause cancer of the uterus.
has she had a uterine biopsy yet?
