This factsheet is for women who have cervical cancer, or who would like information about it, including symptoms, causes and treatments.
Cervical cancer develops if the cells of the cervix (the neck of the womb) become abnormal and grow out of control.

Around 2,900 women in the UK are diagnosed with cervical cancer every year. However, cervical cancer is one of the most preventable cancers.
Deaths from cervical cancer in the UK have fallen over the last 25 years. This reduction is mainly because of the NHS cervical screening programme which detects changes in the cells of your cervix at a pre-cancerous stage. If abnormal cells are caught early, cancer can be prevented.
There are two main types of cervical cancer. Sometimes, cervical cancer can be a mixture of the two types. Squamous cell cancer (the most common) develops in the flat cells covering your cervix. Adenocarcinoma develops in the gland cells that produce mucus, found in the passageway from your cervix to your womb.
There are two main types of cervical cancer - squamous cell cancer (the most common) and adenocarcinoma, although they are often mixed. They are named after the types of cell that become cancerous. Squamous cells are flat cells covering your cervix; adenomatous cells are found in the passageway from your cervix to your womb. Other rarer cancers of the cervix include small cell cancer.
If your smear detects abnormal cells on your cervix, they are usually at an early pre-cancer stage, and don't cause any symptoms. Treating the abnormal cells prevents cancer developing.
If abnormal cells do develop into cervical cancer, you may have the following symptoms:
These symptoms aren't always due to cervical cancer but if you have them, see your GP.
The main cause of cervical cancer is the human papilloma virus (HPV). There are over a hundred different types, or strains, of HPV and each type has a specific number. Some types of HPV cause warts and verrucas, and others increase the risk of cervical cancers.
You may have caught this common virus through sex and be unaware that you have it as it usually causes no symptoms. Your immune system may get rid of the infection so you may never be aware of it. Only a very small proportion of women with HPV will develop cervical cancer.
Although HPV is from the same family as the virus that causes genital warts, having genital warts doesn’t make you more likely to develop cervical cancer. Cervical cancer is caused by a different type of HPV.
Risk factors of cervical cancer include:
If you have had an abnormal screening result, or have symptoms of cervical cancer, your doctor will refer you to a gynaecologist (a doctor who specialises in women’s reproductive health).
You may have a number of tests including the following.
If you’re pregnant, it’s safe for you to have a colposcopy. If any pre-cancerous cells are found, treatment is normally arranged for after your baby has been born. If your doctor suspects you have cancer, you may have a cone biopsy, although this can cause a miscarriage and affect future pregnancies. The results will show what stage your cervical cancer is and how far it has spread.
Your treatment will depend on the stage of your cervical cancer and your general health. You may have a combination of treatments. Your surgeon or oncologist will advise you which treatment is best for you.
If you have very early stage cervical cancer, a cone biopsy may be all you need.
The most common surgical treatment for cervical cancer is a hysterectomy, including removal of the top few centimetres of your vagina and the lymph nodes in your pelvis.
If you have early stage cancer and still wish to have more children, a radical trachelectomy might be possible. Your surgeon will remove most of your cervix but leave the opening behind, so that you may still have a baby afterwards.
Radiotherapy is a treatment to destroy cancer cells with radiation. A beam of radiation is targeted on the cancerous cells, which shrinks the tumour. You may have only radiation, or you may have radiation following surgery.
You may have radiation combined with chemotherapy if the cancer is more advanced or has spread to other areas. This reduces the risk of the cancer coming back. Radiotherapy can be given either from outside the body (external beam radiotherapy) or internally (brachytherapy). These treatments are usually given in sequence.
Chemotherapy is a treatment to destroy cancer cells with medicines. It’s used with radiotherapy, or to help to shrink a tumour before radiotherapy or surgery. It can also control symptoms if cancer comes back after an initial treatment.
The following steps may help to reduce your risk of cervical cancer.
Being diagnosed with cancer can be distressing for you and your family. An important part of cancer treatment is having support to deal with the emotional aspects as well as the physical symptoms. Specialist cancer doctors and nurses are experts in providing the support you need, and may also visit you at home. If you have more advanced cancer, further support is available to you in hospices or at home, and this is called palliative care.
