Can cancer cells be found in a pap smear?

Yes, cancer cells can be found in a Pap smear. A Pap smear is a screening test used to detect pre-cancerous or cancerous cells in the cervix. During a Pap smear, a small sample of cells is collected from the cervix and examined under a microscope. If abnormal cells are found, further testing may be recommended to confirm the diagnosis of cancer.
