Cervical cancer is a disease in which malignant (cancer) cells form in the tissues of the cervix.

The cervix is the lower, narrow end of the uterus (the hollow, pear-shaped organ where a fetus grows). The cervix leads from the uterus to the vagina (birth canal).

Anatomy of the female reproductive system. The organs in the female reproductive system include the uterus, ovaries, fallopian tubes, cervix, and vagina. The uterus has a muscular outer layer called the myometrium and an inner lining called the endometrium.

Cervical cancer usually develops slowly over time. Before cancer appears in the cervix, the cells of the cervix go through changes known as dysplasia. in which abnormal cells begin to appear in the cervical tissue. Over time, the abnormal cells may become cancer cells and start to grow and spread more deeply into the cervix and to surrounding areas.

Cervical cancer in children is rare. For more information, see the PDQ summary on Unusual Cancers of Childhood .

Human papillomavirus (HPV) infection is the major risk factor for cervical cancer.

Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. Talk with your doctor if you think you may be at risk.

Infection of the cervix with human papillomavirus (HPV) is almost always the cause of cervical cancer. Not all women with HPV infection, however, will develop cervical cancer. Women who do not regularly have tests to detect HPV or abnormal cells in the cervix are at increased risk of cervical cancer. There are two vaccines to prevent HPV in girls and young women who do not have HPV. For more information, see the PDQ summary on Cervical Cancer Prevention .

Other possible risk factors include the following:

    Giving birth to many children. Having many sexual partners. Having first sexual intercourse at a young age. Smoking cigarettes. Using oral contraceptives ("the Pill").

There are usually no signs or symptoms of early cervical cancer but it can be detected early with regular check-ups.

Early cervical cancer may not cause signs or symptoms. Women should have regular check-ups, including tests to check for HPV or abnormal cells in the cervix. The prognosis (chance of recovery ) is better when the cancer is found early.

Signs and symptoms of cervical cancer include vaginal bleeding and pelvic pain.

These and other signs and symptoms may be caused by cervical cancer or by other conditions. Check with your doctor if you have any of the following:

    Vaginal bleeding (including bleeding after sexual intercourse). Unusual vaginal discharge . Pelvic pain. Pain during sexual intercourse.

Tests that examine the cervix are used to detect (find) and diagnose cervical cancer.

The following procedures may be used:

    Physical exam and history . An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.

Pelvic exam . An exam of the vagina, cervix, uterus, fallopian tubes. ovaries. and rectum. The doctor or nurse inserts one or two lubricated. gloved fingers of one hand into the vagina and places the other hand over the lower abdomen to feel the size, shape, and position of the uterus and ovaries. A speculum is also inserted into the vagina and the doctor or nurse looks at the vagina and cervix for signs of disease. A Pap test of the cervix is usually done. The doctor or nurse also inserts a lubricated, gloved finger into the rectum to feel for lumps or abnormal areas.

Pelvic exam. A doctor or nurse inserts one or two lubricated, gloved fingers of one hand into the vagina and presses on the lower abdomen with the other hand. This is done to feel the size, shape, and position of the uterus and ovaries. The vagina, cervix, fallopian tubes, and rectum are also checked.

Pap test. A procedure to collect cells from the surface of the cervix and vagina. A piece of cotton, a brush, or a small wooden stick is used to gently scrape cells from the cervix and vagina. The cells are viewed under a microscope to find out if they are abnormal. This procedure is also called a Pap smear.

Pap test. A speculum is inserted into the vagina to widen it. Then, a brush is inserted into the vagina to collect cells from the cervix. The cells are checked under a microscope for signs of disease.

Human papillomavirus (HPV) test . A laboratory test used to check DNA or RNA for certain types of HPV infection. Cells are collected from the cervix and DNA or RNA from the cells is checked to find out if an infection is caused by a type of HPV that is linked to cervical cancer. This test may be done using the sample of cells removed during a Pap test. This test may also be done if the results of a Pap test show certain abnormal cervical cells.

Endocervical curettage . A procedure to collect cells or tissue from the cervical canal using a curette (spoon-shaped instrument). Tissue samples may be taken and checked under a microscope for signs of cancer. This procedure is sometimes done at the same time as a colposcopy .

Colposcopy . A procedure in which a colposcope (a lighted, magnifying instrument) is used to check the vagina and cervix for abnormal areas. Tissue samples may be taken using a curette (spoon-shaped instrument) and checked under a microscope for signs of disease.

Biopsy . If abnormal cells are found in a Pap test, the doctor may do a biopsy. A sample of tissue is cut from the cervix and viewed under a microscope by a pathologist to check for signs of cancer. A biopsy that removes only a small amount of tissue is usually done in the

doctor’s office. A woman may need to go to a hospital for a cervical cone biopsy (removal of a larger, cone-shaped sample of cervical tissue).

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis (chance of recovery) depends on the following:

    The stage of the cancer (the size of the tumor and whether it affects part of the cervix or the whole cervix, or has spread to the lymph nodes or other places in the body). The type of cervical cancer. The patient's age and general health. Whether the patient has a certain type of human papillomavirus (HPV). Whether the patient has human immunodeficiency virus (HIV). Whether the cancer has just been diagnosed or has recurred (come back).

Treatment options depend on the following:

    The stage of the cancer. The type of cervical cancer. The patient's desire to have children. The patient’s age.

Treatment of cervical cancer during pregnancy depends on the stage of the cancer and the stage of the pregnancy. For cervical cancer found early or for cancer found during the last trimester of pregnancy, treatment may be delayed until after the baby is born. For more information, see the section on Cervical Cancer During Pregnancy .

Stages of Cervical Cancer

After cervical cancer has been diagnosed, tests are done to find out if cancer cells have spread within the cervix or to other parts of the body.

The process used to find out if cancer has spread within the cervix or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment.

The following tests and procedures may be used in the staging process:

    CT scan (CAT scan). A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.

PET scan (positron emission tomography scan). A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.

MRI (magnetic resonance imaging). A procedure that uses a magnet, radio waves. and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).

Ultrasound exam. A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. This picture can be printed to be looked at later.

Chest x-ray . An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.

Cystoscopy . A procedure to look inside the bladder and urethra to check for abnormal areas. A cystoscope is inserted through the urethra into the bladder. A cystoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer.

Laparoscopy . A surgical procedure to look at the organs inside the abdomen to check for signs of disease. Small incisions (cuts) are made in the wall of the abdomen and a laparoscope (a thin, lighted tube) is inserted into one of the incisions. Other instruments may be inserted through the same or other incisions to perform procedures such as removing organs or taking tissue samples to be checked under a microscope for signs of disease.

Pretreatment surgical staging. Surgery (an operation) is done to find out if the cancer has spread within the cervix or to other parts of the body. In some cases, the cervical cancer can be removed at the same time. Pretreatment surgical staging is usually done only as part of a clinical trial.

The results of these tests are viewed together with the results of the original tumor biopsy to determine the cervical cancer stage.

There are three ways that cancer spreads in the body.

    Tissue. The cancer spreads from where it began by growing into nearby areas. Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.

Cancer may spread from where it began to other parts of the body.

When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor ) and travel through the lymph system or blood.

    Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body. Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body.

The metastatic tumor is the same type of cancer as the primary tumor. For example, if cervical cancer spreads to the lung. the cancer cells in the lung are actually cervical cancer cells. The disease is metastatic cervical cancer, not lung cancer.

The following stages are used for cervical cancer:

Carcinoma in Situ (Stage 0)
