Cervical Cancer (Cancer of the Cervix)

Cervical cancer facts*

*Cervical cancer facts medical author: Melissa Conrad Stöppler, MD

Causes and risk factors for cervical cancer have been identified and include human papillomavirus (HPV) infection, having many sexual partners, smoking, taking birth control pills, and engaging in early sexual contact.
HPV infection may cause cervical dysplasia, or abnormal growth of cervical cells.
Regular pelvic exams and Pap testing can detect precancerous changes in the cervix.
Precancerous changes in the cervix may be treated with cryosurgery, cauterization, or laser surgery.
The most common symptoms and signs of cervical cancer are abnormal vaginal bleeding, increased vaginal discharge, bleeding after going through menopause, pain during sex, and pelvic pain.
Cervical cancer can be diagnosed using a Pap smear or other procedures that sample the cervix tissue.
Chest X-rays, CT scan, MRI, and a PET scan may be used to determine the stage of cervical cancer.
Cancer of the cervix requires different treatment than cancer that begins in other parts of the uterus.
Treatment options for cervical cancer include radiation therapy, surgery, and chemotherapy.
Two vaccines, Gardasil and Cervarix, are available to prevent HPV infection.
The prognosis of cervical cancer depends upon the stage and type of cervical cancer and the tumor size.

What is the cervix?

The cervix is part of a woman's reproductive system. It's in the pelvis. The cervix is the lower, narrow part of the uterus (womb).
The cervix is a passageway:

The cervix connects the uterus to the vagina. During a menstrual period, blood flows from the uterus through the cervix into the vagina. The vagina leads to the outside of the body.
The cervix makes mucus. During sex, mucus helps sperm move from the vagina through the cervix into the uterus.
During pregnancy, the cervix is tightly closed to help keep the baby inside the uterus. During childbirth, the cervix opens to allow the baby to pass through the vagina.

What is cancer?

Cancer begins in cells, the building blocks that make up tissues. Tissues make up the cervix and other organs of the body.
Normal cervical cells grow and divide to form new cells as the body needs them. When normal cells grow old or get damaged, they die, and new cells take their place.
Sometimes, this process goes wrong. New cells form when the body does not need them, and old or damaged cells do not die as they should. The buildup of extra cells often forms a mass of tissue called a growth or tumor.
Growths on the cervix can be benign (not cancer) or malignant (cancer):

Benign growths (polyps, cysts, or genital warts):
- are rarely a threat to life
- don't invade the tissues around them
Malignant growths (cervical cancer):
- may become a threat to life if not found soon enough
- can invade nearby tissues and organs
- can spread to other parts of the body

Cervical cancer begins in cells on the surface of the cervix. Over time, the cervical cancer can invade more deeply into the cervix and nearby tissues.
Cervical cancer cells can spread by breaking away from the cervical tumor. They can travel through lymph vessels to nearby lymph nodes. Also, cancer cells can spread through the blood vessels to the lungs, liver, or bones. The process of spreading of cancer cells from the tissue in which they arise to other tissues elsewhere is called metastasis.
After spreading, cancer cells may attach to other tissues and grow to form new tumors that may damage those tissues. See the Staging section for information about cervical cancer that has spread.

Risk factors

When you get a diagnosis of cervical cancer, it's natural to wonder what may have caused the disease. Doctors usually can't explain why one woman develops cervical cancer and another doesn't.
However, we do know that a woman with certain risk factors may be more likely than other women to develop cervical cancer. A risk factor is something that may increase the chance of developing a disease.
Studies have found that infection with the virus called HPV is the cause of almost all cervical cancers. More than half of women by the age of 50 have been exposed to HPV, but most HPV infections clear up on their own. An HPV infection with a high risk type of HPV that doesn't go away can cause cervical cancer in some women.
Other risk factors, such as smoking, can act to increase the risk of cervical cancer among women infected with HPV even more.
A woman's risk of cervical cancer can be reduced by getting regular cervical cancer screening tests. If abnormal cervical cell changes are found early, cancer can be prevented by removing or killing the changed cells before they become cancer cells.
Another way a woman can reduce her risk of cervical cancer is by getting an HPV vaccine before becoming sexually active (between the ages of 9 and 26). Even women who get an HPV vaccine need regular cervical cancer screening tests. Vaccines reduce a person's risk of getting an infection, but do not prevent such infections in every vaccinated person.

Symptoms

Early cervical cancers usually don't cause symptoms. When the cancer grows larger, women may notice abnormal vaginal bleeding:

Bleeding that occurs between regular menstrual periods
Bleeding after sexual intercourse, douching, or a pelvic exam
Menstrual periods that last longer and are heavier than before
Bleeding after going through menopause

Women may also notice...

Increased vaginal discharge
Pelvic pain
Pain during sex

Cervical cancer, infections, or other health problems may cause these symptoms. A woman with any of these symptoms should tell her doctor so that problems can be diagnosed and treated as early as possible.

Diagnosis

Share Your Story

If you have symptoms of cervical cancer, your doctor will try to find out what's causing the problems. You may have the following tests:

Lab tests: The doctor or nurse scrapes a sample of cells from the cervix. For a Pap test, the lab checks the sample for cervical cancer cells or abnormal cells that could become cancer later if not treated. For an HPV test, the same or a similar sample is tested for HPV infection. HPV can cause cell changes and cervical cancer.
Cervical exam: The doctor uses a colposcope to look at the cervix. The colposcope combines a bright light with a magnifying lens to make tissue easier to see. This exam is usually done in the doctor's office or clinic.
Tissue sample: The removal of tissue to look for cancer cells is a biopsy. Most women have cervical tissue removed in the doctor's office, and usually only local anesthesia is needed.

The doctor will remove tissue in one of the following ways:

Punch biopsy: The doctor uses a sharp tool to pinch off small samples of cervical tissue.
LEEP: The doctor uses an electric wire loop to slice off a thin, round piece of cervical tissue.
Endocervical curettage: The doctor uses a curette (a small, spoon-shaped instrument) to scrape a small sample of tissue from the cervical canal. Some doctors may use a thin, soft brush instead of a curette.
Cone biopsy: The doctor removes a cone-shaped sample of tissue. A cone biopsy lets the pathologist look at the tissue beneath the surface of the cervix to learn whether it has abnormal cells. The doctor may do this test in the hospital under general anesthesia.

A pathologist checks the tissue under a microscope for cancer cells. In most cases, a biopsy is the only sure way to tell whether cancer is present.
Removing tissue from the cervix may cause some bleeding or other discharge. The area usually heals quickly. Some women also feel some pain similar to menstrual cramps. Your doctor can suggest medicine that will help relieve any pain.
You may want to ask the doctor these questions before having a biopsy:

Which biopsy method do you recommend?
How will tissue be removed?
Will I have to go to the hospital?
How long will it take? Will I be awake? Will it hurt?
Are there any risks? What are the chances of infection or bleeding after the test?
For how many days afterward should I avoid using tampons, douching, or having sex?
Can the test affect my ability to get pregnant and have children?
How soon will I know the results? Who will explain them to me?
If I do have cancer, who will talk to me about the next steps? When?

Staging

If the biopsy shows that you have cancer, your doctor will need to learn the extent (stage) of the disease to help you choose the best treatment. The stage is based on whether the cancer has invaded nearby tissues or spread to other parts of the body. Cervical cancer spreads most often to nearby tissues in the pelvis or to lymph nodes. It may also spread to the lungs, liver, or bones.
When cancer spreads from its original place to another part of the body, the new tumor has the same kind of cancer cells and the same name as the original tumor. For example, if cervical cancer spreads to the lungs, the cancer cells in the lungs are actually cervical cancer cells. The disease is metastatic cervical cancer, not lung cancer. It's treated as cervical cancer, not as lung cancer. Doctors sometimes call the new tumor in the lung "distant" disease or a distant metastasis.
Your doctor will do a pelvic exam, will feel for swollen lymph nodes, and may remove additional tissue. To learn the extent of disease, your doctor may order one or more tests:

Chest X-ray: An X-ray of the chest can often show whether cancer has spread to the lungs.
CT scan (CAT scan): An X-ray machine linked to a computer takes a series of detailed pictures of your pelvis, abdomen, or chest. Before a CT scan, you may receive contrast material by injection in your arm or hand, by mouth, or by enema. The contrast material makes abnormal areas easier to see. A tumor in the liver, lungs, or elsewhere in the body can show up on the CT scan.
MRI: A powerful magnet linked to a computer makes detailed pictures of your pelvis and abdomen. Before MRI, you may receive an injection of contrast material. MRI can show whether cancer has invaded tissues near the cervix or has spread from the cervix to tissues in the pelvis or abdomen.
PET scan: Cancer cells often take up or concentrate sugar- or glucose- more than normal tissues. Radioactive glucose can be given as an injection into a vein. Pictures are then made using a machine which images the areas of radioactive glucose in the body. Combining those images with a CT scan can provide excellent information on the presence or absence of spread of the cancer.

The stage is based on where cancer is found. These are the stages of invasive cervical cancer:

Stage I: Cancer cells are found only in the cervix.
Stage II: The tumor has grown through the cervix and invaded the upper part of the vagina. It may have invaded other nearby tissues but not the pelvic wall (the lining of the part of the body between the hips) or the lower part of the vagina.
Stage III: The tumor has invaded the pelvic wall or the lower part of the vagina. If the tumor is large enough to block one or both of the tubes through which urine passes from the kidneys, lab tests may show that the kidneys aren't working well.
Stage IV: The tumor has invaded the bladder or rectum. Or, the cancer has spread to other parts of the body, such as the lungs.

Treatment

Treatment options for women with cervical cancer are...

Surgery
Radiation therapy
Chemotherapy
A combination of these methods

The choice of treatment depends mainly on the size of the tumor and whether the cancer has spread. The treatment choice may also depend on whether you would like to become pregnant someday.
Your doctor may refer you to a specialist, or you may ask for a referral. You may want to see a gynecologic oncologist, a doctor who specializes in treating female cancers. Other specialists who treat cervical cancer include gynecologists, medical oncologists, and radiation oncologists.
Your health care team may also include an oncology nurse and a registered dietitian. Your health care team can describe your treatment choices, the expected results of each, and the possible side effects. Because cancer treatments often damage healthy cells and tissues, side effects are common. These side effects depend on many factors, including the type of treatment. Side effects may not be the same for each person, and they may even change from one treatment session to the next. Before treatment starts, ask your health care team about possible side effects and how treatment may change your normal activities. You and your health care team can work together to develop a treatment plan that meets your medical and personal needs.
At any stage of the disease, supportive care is available to control pain and other symptoms, to relieve the side effects of treatment, and to ease emotional concerns. You can get information about coping on NCI's website at http://www.cancer.gov/cancertopics/coping.
Also, you can get information about supportive care from NCI's Cancer Information Service at 1-800-4-CANCER (1-800-422-6237). Or, chat using LiveHelp, NCI's instant messaging service, at http://www.cancer.gov/livehelp.
You may want to talk with your doctor about taking part in a clinical trial. Clinical trials are research studies testing new treatments. They are an important option for women with all stages of cervical cancer. See the section on Taking Part in Cancer Research 4.
You may want to ask the doctor these questions before treatment begins:

What is the stage of my disease? Has the cancer spread? If so, where?
May I have a copy of the report from the pathologist?
What are my treatment choices? Which do you recommend for me? Will I have more than one kind of treatment?
What are the expected benefits of each kind of treatment?
What are the risks and possible side effects of each treatment? What can we do to control the side effects?
What can I do to prepare for treatment?
Will I have to stay in the hospital? If so, for how long?
What is the treatment likely to cost? Will my insurance cover the cost?
How will treatment affect my normal activities?
How may treatment affect my sex life?
Will I be able to get pregnant and have children after treatment? Should I preserve eggs before treatment starts?
What can I do to take care of myself during treatment?
What is my chance of a full recovery?
How often will I need checkups after treatment?
Would a research study (clinical trial) be right for me?

Surgery

Share Your Story

Surgery is an option for women with Stage I or II cervical cancer. You and your surgeon can talk about the types of surgery and which may be right for you.
If you have a small tumor, the type of surgery may depend on whether you want to get pregnant and have children later on. Some women with very early cervical cancer may decide with their surgeon to have only the cervix, part of the vagina, and the lymph nodes in the pelvis removed (radical trachelectomy).
Other women may choose to have the cervix and uterus removed (complete hysterectomy). The surgeon may also remove some tissue around the cervix, part of the vagina, the fallopian tubes, or the ovaries. In addition, the surgeon may remove lymph nodes near the tumor.
It's common to feel tired or weak for a while after surgery for cervical cancer. The time it takes to heal is different for each woman. You'll probably be able to leave the hospital within a couple of days. Most women return to their normal activities within 4 to 8 weeks after surgery.
You may have pain or discomfort for the first few days after surgery. Medicine can help control your pain. Before surgery, you should discuss the plan for pain relief with your health care team. After surgery, they can adjust the plan if you need more pain control.
After a trachelectomy, some women need to have a tube put into the bladder to drain urine. It usually can be removed a few days after surgery.
After a hysterectomy, some women become constipated or have nausea and vomiting. In addition, some women lose control of their bladder or have trouble emptying their bladder. These effects are usually temporary. After a hysterectomy, you'll stop having menstrual periods, and you won't be able to become pregnant.
After the ovaries are removed, menopause occurs at once. You may have hot flashes, vaginal dryness, and night sweats. These symptoms are caused by the sudden loss of female hormones. Talk with your health care team about your symptoms so that you can develop a treatment plan together. There are drugs and lifestyle changes that can help, and most symptoms go away or lessen with time.
Surgery to remove lymph nodes may cause swelling (lymphedema) in one or both legs. Ask your health care team about how you may prevent or control the swelling. Information about lymphedema is available on NCI's website at http://www.cancer.gov/cancertopics/coping.
For some women, surgery to remove the cervix and nearby tissues can affect sexual intimacy. You may have feelings of loss that make intimacy difficult. Sharing these feelings with your partner may be helpful. Sometimes couples talk with a counselor to help them express their concerns.
You may want to ask the doctor these questions before having surgery:

Do you recommend surgery for me? If so, which kind? Will my ovaries be removed? Do I need to have lymph nodes removed?
What is the goal of surgery?
What are the risks of surgery?
How will I feel after surgery? If I have pain, how will it be controlled?
How long will I have to be in the hospital?
Will I have any lasting side effects?
When will I be able to resume normal activities?

Radiation therapy

Radiation therapy uses high-energy rays to kill cancer cells. It's an option for women with any stage of cervical cancer. Women with early cervical cancer may choose radiation therapy instead of surgery. It also may be used after surgery to destroy any cancer cells that remain in the area. Women with cancer that extends beyond the cervix may have radiation therapy and chemotherapy.
Doctors use two types of radiation therapy to treat cervical cancer. Some women receive both types:

External radiation therapy: A large machine directs radiation at your pelvis or other areas with cancer. The treatment usually is given in a hospital or clinic. You may receive external radiation therapy 5 days a week for several weeks. Each treatment takes only a few minutes.
Internal radiation therapy (also called brachytherapy): A narrow cylinder is placed inside your vagina, and a radioactive substance is loaded into the cylinder. Usually, a session of internal radiation therapy lasts only a few minutes. The cylinder and substance are removed, and you can go home. The short session may be repeated two or more times over several weeks. When the radioactive substance is removed, no radioactivity is left in your body. With a less common method of internal radiation therapy, you may stay in the hospital for several days during treatment.

Although radiation therapy is painless, it may cause side effects. The side effects depend mainly on how much radiation is given and which part of your body is treated. Radiation to the abdomen and pelvis may cause nausea, vomiting, diarrhea, or urinary problems. You may lose hair in your genital area. Also, skin on the abdomen and pelvis may become red, dry, and tender.
You may have dryness, itching, or burning in your vagina. Your doctor may advise you to wait until a few weeks after radiation treatment ends to have sex.
You are likely to become tired during radiation therapy, especially in the later weeks of treatment. Resting is important, but doctors usually advise patients to try to stay as active as they can.
Although the side effects of radiation therapy can be upsetting, they can usually be treated or controlled. Talk with your doctor or nurse about ways to relieve discomfort.
It may also help to know that most side effects go away when treatment ends. However, you may want to discuss with your doctor the possible long-term effects of radiation therapy. For example, radiation therapy may make the vagina narrower. A narrow vagina can make sex or follow-up exams difficult. There are ways to prevent this problem. If it does occur, however, your health care team can tell you about ways to expand the vagina.
Another possible long-term effect is damage to the ovaries. Menstrual periods usually stop, and women may have hot flashes and vaginal dryness. Menstrual periods may return for some women, especially younger women. Women who may want to get pregnant after radiation therapy should ask their health care team about ways to preserve their eggs before treatment starts.
You may want to ask the doctor these questions before having radiation therapy:

What is the goal of this treatment?
How will the radiation be given?
Will I need to stay in the hospital? If so, for how long?
When will the treatments begin?
How often will I have them? When will they end?
How will I feel during treatment? Are there side effects?
How will we know if the radiation therapy is working?
Will I be able to continue my normal activities during treatment?
How will radiation therapy affect my sex life?
Are there lasting side effects?

Chemotherapy

Chemotherapy uses drugs to kill cancer cells. For the treatment of cervical cancer, chemotherapy is usually combined with radiation therapy. For cancer that has spread to distant organs, chemotherapy may be used alone.
Most drugs for cervical cancer are given directly into a vein (intravenously) through a thin needle. Some drugs can be taken by mouth. Most women receive chemotherapy in a clinic or at the doctor's office. Drugs that are swallowed may be taken at home instead. Some women need to stay in the hospital during treatment.
The side effects depend mainly on which drugs are given and how much. Chemotherapy kills fast-growing cancer cells, but the drugs can also harm normal cells that divide rapidly:

Blood cells: When chemotherapy lowers the levels of healthy blood cells, you're more likely to get infections, bruise or bleed easily, and feel very weak and tired. Your health care team will check for low levels of blood cells. If the levels are low, your health care team may stop the chemotherapy for a while or reduce the dose of drug. They may also give you medicines that can help your body make new blood cells.
Cells in hair roots: Chemotherapy may cause hair loss. If you lose your hair, it will grow back, but it may change in color and texture for a while. Ultimately it will return to being naturally as it was before.
Cells that line the digestive tract: Chemotherapy can cause a poor appetite, nausea and vomiting, diarrhea, or mouth and lip sores. Your health care team can give you medicines and suggest other ways to help with these problems.

Other side effects include skin rash, tingling or numbness in your hands and feet, hearing problems, loss of balance, joint pain, or swollen legs and feet. Your health care team can suggest ways to control many of these problems. Most go away when treatment ends.
You may want to ask the doctor these questions before having chemotherapy:

Why do I need this treatment?
Which drug or drugs will I have?
How do the drugs work?
What are the expected benefits of the treatment?
What are the risks and possible side effects of treatment? What can we do about them?
When will treatment start? When will it end?
How will treatment affect my normal activities?

Second opinion

Before starting treatment, you might want a second opinion about your diagnosis, stage of cancer, and treatment plan. Some people worry that the doctor will be offended if they ask for a second opinion. Usually the opposite is true. Most doctors welcome a second opinion. And many health insurance companies will pay for a second opinion if you or your doctor requests it. Some companies require a second opinion.
If you get a second opinion, the second doctor may agree with your first doctor's diagnosis and treatment plan. Or, the second doctor may suggest another approach. Either way, you have more information and perhaps a greater sense of control. You can feel more confident about the decisions you make, knowing that you've looked at all of your options.
It may take some time and effort to gather your medical records and see another doctor. In most cases, it's not a problem to take several weeks to get a second opinion. The delay in starting treatment usually will not make treatment less effective. To make sure, you should discuss this delay with your doctor.
There are many ways to find a doctor for a second opinion. You can ask your doctor, a local or state medical society, or a nearby hospital or medical school for names of specialists.

Nutrition

Eating well is important before, during, and after cancer treatment. You need the right amount of calories to maintain a good weight. You also need enough protein to keep up your strength. Eating well may help you feel better and have more energy.
Sometimes, especially during or soon after treatment, you may not feel like eating. You may be uncomfortable or tired. You may find that foods don't taste as good as they used to. In addition, poor appetite, nausea, vomiting, mouth blisters, and other side effects of treatment can make it hard for you to eat.
Your doctor, a registered dietitian, or another health care provider can suggest ways to help you meet your nutrition needs.

Follow-up care

You'll need regular checkups (such as every 3 to 6 months) after treatment for cervical cancer. Checkups help ensure that any changes in your health are noted and treated if needed. If you have any health problems between checkups, contact your doctor.
Cervical cancer may come back after treatment. Your doctor will check for the return of cancer. Checkups may include a physical exam, Pap test, and chest X-ray.
You may want to ask your doctor these questions after you have finished treatment:

How often will I need checkups?
How often will I need a Pap test?
What other follow-up tests do you suggest for me?
Between checkups, what health problems or symptoms should I tell you about?

Sources of support

Learning that you have cervical cancer can change your life and the lives of those close to you. These changes can be hard to handle. It's normal for you, your family, and your friends to need help coping with the feelings that a diagnosis of cancer can bring.
Concerns about treatments and managing side effects, hospital stays, and medical bills are common. You may also worry about caring for your family, keeping your job, or continuing daily activities.
Here's where you can go for support:

Doctors, nurses, and other members of your health care team can answer questions about treatment, working, or other activities.
Social workers, counselors, or members of the clergy can be helpful if you want to talk about your feelings or concerns. Often, social workers can suggest resources for financial aid, transportation, home care, or emotional support.
Support groups also can help. In these groups, patients or their family members meet with other patients or their families to share what they have learned about coping with cancer and the effects of treatment. Groups may offer support in person, over the telephone, or on the Internet. You may want to talk with a member of your health care team about finding a support group.
NCI's Cancer Information Service can help you locate programs, services, and NCI publications. Call 1-800-4-CANCER (1-800-422-6237). Or, chat using LiveHelp, NCI's instant messaging service, at http://www.cancer.gov/livehelp.
Your doctor or a sex counselor may be helpful if you and your partner are concerned about the effects of cervical cancer on your sex life. Ask your doctor about possible treatment of side effects and whether these effects are likely to last. Whatever the outlook, you and your partner may find it helps to discuss your concerns.

Taking part in cancer research

Doctors all over the world are conducting many types of clinical trials (research studies in which people volunteer to take part). Research has already led to advances in the prevention, diagnosis, and treatment of cervical cancer.
Doctors continue to search for new and better ways to treat cervical cancer. They are testing new treatments, including new drugs, combinations, and schedules. Some studies are combining surgery, chemotherapy, and radiation therapy.
Clinical trials are designed to find out whether new treatments are safe and effective. Even if the women in a trial don't benefit directly, they may still make an important contribution by helping doctors learn more about cervical cancer and how to control it. Although clinical trials may pose some risks, researchers do all they can to protect their patients.
If you're interested in being part of a clinical trial, talk with your doctor.
NCI's website includes a section on clinical trials at http://www.cancer.gov/clinicaltrials. It has general information about clinical trials as well as detailed information about specific ongoing studies of cervical cancer.
NCI's Cancer Information Service can answer your questions and provide information about clinical trials. Contact CIS at 1-800-4-CANCER (1-800-422-6237) or at LiveHelp at http://www.cancer.gov/livehelp.
