Cervical cancer

Cervical cancer is a type of cancer that develops in a woman's cervix. The cervix is the entrance to the womb from the vagina. Over the course of many years, the cells lining the surface of the cervix undergo a series of changes. In rare cases, these changed cells can become cancerous.

Normally, cells grow and multiply in an orderly way; however, damaged genes can cause them to behave abnormally.

They may grow into a lump called a 'tumour'. Tumours can be benign (not cancer) or malignant (cancer).

Polyps, cysts, and genital warts are types of benign growths on the cervix.

A malignant tumour is made up of cancer cells. If these cells are not treated, they may spread beyond their normal boundaries and into surrounding tissues, becoming invasive cancer.

The two main types of cervical cancer are named after the type of cells from which they originate:

  • Squamous cell carcinoma - this is the most common type of cervical cancer, accounting for about 80% of all cases. It starts in the skin-like squamous cells of the cervix.
  • Adenocarcinoma - this is a less common type of cervical cancer, which develops from the glandular cells. Adenocarcinoma is more difficult to diagnose because it originates higher in the cervix and is more difficult to reach with the brush or spatula used in taking a Pap test.

Cervical cancer often has no symptoms in its early stages. If you have symptoms, the most common is unusual vaginal bleeding which can occur after sex, in between periods or after menopause.

Abnormal bleeding doesn't mean that you have cervical cancer, but it's important to see your doctor as soon as possible. If your doctor suspects you might have cervical cancer, you should be referred to see a specialist as soon as possible.

Cervical cancer is one of few cancers where screening can detect pre-cancerous lesions. Having a regular Pap test (sometimes referred to as a 'Pap smear') is the best form of detection.

The National Cervical Screening Program (NCSP) recommends women between the ages of 18 (or two years after first sexual intercourse, whichever is later) and 69 years should have a Pap test every two years.

For further information visit the NCSP website at or contact your doctor, health centre or family planning clinic, or phone 13 15 56 (for the cost of a local call).

Changes to cervical screening

From 1 December 2017 the National Cervical Screening Program will change to improve early detection. The current 2 yearly Pap test will change to a 5 yearly HPV test.

What should I do before 1 December 2017?
If you are a woman aged 18 to 69, you should continue to have your regular Pap test every 2 years.

When will I be due for my first HPV test?
Women will be due for the first HPV test 2 years after their last Pap test.

Cervical screening (Pap smear) and prevention | Health and wellbeing | Queensland Government

Regular cervical screening via a Pap smear is the best way to prevent cervical cancer as it can detect changes to the cells of the cervix that can be treated before cancer develops. In Queensland, the Queensland Health Pap Smear Register will send you a reminder notice when you are overdue for a Pap smear as well as providing access to your Pap smear result history for your doctor or pathology laboratory.
