What is cervical cancer?

Cervical cancer develops in the cervix, which is the opening to the uterus (sometimes called womb).

Almost all cases of cervical cancer are caused by a virus called the human papillomavirus (HPV).

HPV is a very common virus, with lots of different strains. Most people will get some type of it during their life.

A lot of types of HPV are harmless, but some can cause changes in cells that can sometimes lead to cancer.

HPV is usually spread during sex. It doesn’t have to be penetrative sex – it can be spread through skin-to-skin contact, oral sex and sharing sex toys, as well as vaginal and anal sex.

Because of how it is usually spread, HPV can cause changes to cells which can lead to cancers in different parts of the body, like the cervix, penis, anus, vulva, vagina, and some kinds of head and neck cancers.

Since 2008, girls aged 12-13 in the UK have been offered vaccination against HPV.

Since 2019, some boys have also been offered the vaccination.

Cervical cancer symptoms

The most common symptom of cervical cancer is bleeding from the vagina.

If you notice bleeding between periods or during/after sex, you should book an appointment with a doctor straightaway.

Noticing blood doesn’t mean you have cancer. Unusual bleeding can be a sign of lots of different things that are also important to rule out, like infections. Your GP will be able to run through what might be happening.

Other symptoms of cervical cancer can be:

  • pain in your pelvis
  • pain during sex
  • a bad-smelling discharge from your vagina.

How is cervical cancer diagnosed?

If you spot signs which could be cervical cancer, your doctor might arrange for you to have a colposcopy.

This is where a specialist looks inside your vagina using a small microscope with a light at the end. A tissue sample might be taken during the colposcopy so it can be looked at closely for cancer cells under a microscope.

Cervical cancer treatment

Cervical cancer is treated differently depending on what stage it’s at.

If cells are found in your cervix that are abnormal but haven’t turned cancerous, doctors can use different treatments to kill or get rid of them. This doesn’t usually hurt, and is sometimes done by a laser or small electric current being applied to the affected area.

If cells have become cancerous but the cancer is found early on, you will usually have an operation to remove the cervix and all or part of the uterus. You could also be offered radiotherapy to kill the cancerous cells.

If the cancer is more advanced then you will be offered radiotherapy, and maybe a combination of chemotherapy and surgery.
