Is cervical cancer common in women who had hysterectomy's?

A person can still get cervical cancer even if one has had a total hysterectomy.

Likewise, a person can still have a breast cancer recurrence in the ribs even if they have had a total masectomy.

However, a positive pap smear can indicate other conditions besides cervical cancer.

Talk to your Mom's doctor.

Cervix is part of uterus and hysterectomy is removal of uterus.Hence when the uterus is removed which includes the cervix,from where does the question of cancer of cervix arise ?
No

Women sometimes have a hysterectomy for cervical cancer.

In a total hysterectomy, the cervix is taken out and there is usually no cervix left for a cancer to grow in.

However, there is an operation called a subtotal hysterectomy where most of the uterus is removed and a small bit of cervix is left behind. Cervical cancer can form in this remnant of cervix - usually at rates equal to the normal population incidence.
