Ask the experts
My wife had an abnormal pap smear test which resulted in the
doctor indicating she had abnormal cells on her cervix.
She had a hysterectomy to correct the problem but does this mean she could have
developed cancer and does this predispose her to have cancer in the future?
While we do not know the specific medical details involved in this situation, several general comments can be made about women who have had a hysterectomy for cervix abnormalities. If the hysterectomy was done for dysplasia (see MedicineNet.com's Pap Smear article), then it may recur in the vagina in about 1-2% of patients who have had hysterectomy. On the other hand, if a radical hysterectomy was done because of cervix cancer, recurrence rate may be up to 9%. Recurrence probably depends somewhat on how advanced the cancer was, and it definitely depends on what type of hysterectomy was performed.
One thing is certain in all women who have had hysterectomy for cervix abnormalities; even though risk of recurrence is pretty low, they need to be screened lifelong for recurrence by having a vaginal sample (vaginal smear) annually, or more often according to the doctor's advice.
Thank you for your question.
