CauseCervical cancer is caused by severe abnormal changes in the cells of the cervix . Most precancerous or cancerous cell changes occur in the cervix at the transformation zone because these cells normally undergo constant change. During this natural process of change, some cervical cells can become abnormal if you are infected with high-risk types of HPV. Other factors that may play a role in causing cervical cancer include:
Regular Pap test screening is the single most important tool to identify cervical cell changes early before they progress to cancer. SymptomsSince abnormal cervical cell changes rarely cause symptoms, it is important to have regular Pap test screening. If cervical cell changes progress to cervical cancer , symptoms may develop. Symptoms of cervical cancer may include:
Symptoms that may occur when your cervical cancer has progressed include:
What HappensIf cervical cancer is not treated, it may spread from the cervix to the vagina, then into deeper tissue layers of connective tissue around the uterus. As it progresses, it may spread to the pelvic lymph nodes and other pelvic organs. Advanced-stage cancer may spread to lymph nodes, to other organs in the pelvis, causing problems with kidney and bowel function, or to other organs in the body, such as the liver and lungs. Cervical cancer is classified in stages that are determined by the size of the cancer and how far it has spread to nearby tissues and other organs, such as the lungs, the liver, or bones. Your doctor will determine the stage of your cervical cancer by gathering information from a variety of tests, including X-rays. The stage of your cancer is one of the most important factors in selecting the treatment option that is right for you. The long-term outcome (prognosis) depends on the stage of your cervical cancer. What Increases Your RiskThe most common cause of cervical cancer is a persistent infection with a high-risk type of human papillomavirus (HPV ). HPV infection of the cervix is a sexually transmitted disease (STD) . A past HPV infection in you or your partner can cause abnormal cervical cell changes years later because the virus may remain in the body for life. HPV infection usually does not cause symptoms and often goes away without causing any problems, so you or your partner may not be aware of a current or past HPV infection. Other risk factors that may increase your risk for cervical cancer include:
Pregnant women have the same risk of developing cervical cancer as nonpregnant women. When To Call a DoctorIf you have been diagnosed with cervical cancer , be sure to follow your doctor's instructions about calling when you have problems, new symptoms, or symptoms that get worse. If you are concerned about your symptoms or if you think you have an increased risk for cervical cancer, call your health professional if you have:
Watchful WaitingRegular Pap test screening is the most important tool in identifying and treating cervical cell changes before they progress to cervical cancer. After cervical cancer has been diagnosed, it should be treated. Watchful waiting is not appropriate. Who To SeeHealth professionals who can evaluate your symptoms and your risk factors, and who can diagnose cervical cancer include:
Doctors who can manage your cancer treatment include: To prepare for your appointment, see the topic Making the Most of Your Appointment. Exams and TestsThe Pap test is a routine screening test used to identify abnormal cell changes of the cervix and to screen for cervical cancer . Regular Pap test screening is the single most important tool in identifying and treating cervical cell changes before they progress to cervical cancer. If cervical cancer is suspected, your doctor will take a medical history and perform a physical exam, including a pelvic exam and a Pap test. Several follow-up tests may be needed for evaluation and treatment. Tests to confirm a diagnosis of cervical cancer include:
If you are pregnant, a colposcopy and cervical biopsy can be done to confirm cervical cancer. Tests to determine the extent (stage) of cervical cancer include:
Other surgeries may be done to determine the extent of cervical cancer. For more information, see the Surgery section of this topic. Tests to guide treatment decisions include:
Early DetectionAs part of your routine gynecological exam, you should have a Pap test. A Pap test is used to identify abnormal cell changes of your cervix and to screen for cervical cancer. The Pap test is the most effective screening test to prevent the development of cervical cancer. Abnormal cervical cells on a Pap test are classified according to their degree of abnormality. Treatment decisions are guided by the kind of changes seen in the cells. In North America, abnormal cells are classified using the Bethesda system (TBS). The Bethesda system or other classification systems are used in other parts of the world. Treatment OverviewCervical cancer detected in its early stages can be cured with treatment and close follow-up. Treatment choices for cervical cancer may include one or more of the following therapies:
Your quality of life becomes a critical issue when considering treatment options. Be sure to discuss your personal preferences with your oncologist when he or she recommends treatment. Initial treatmentThe choice of treatment and the long-term outcome (prognosis) of cervical cancer depends on the type and stage of cancer. Your age, overall health, quality of life, and desire to be able to have children must also be considered. Treatment choices for cervical cancer may be a single therapy or a combination of therapies, such as:
Chemotherapy may be given at the same time as radiation therapy (chemoradiation). Studies show that chemotherapy given at the same time as radiation treatment (chemoradiation) improves survival rates in stages IIB, IIIA, IIIB, and IVA cervical cancer without significantly increasing the side effects of either treatment. Chemoradiation may also improve survival rates in stages IB and IIA for women with large tumors. 7, 8, 3 Compared with radiation alone, chemoradiation improves survival. 9 It is usually used as the primary therapy or after a hysterectomy. Microinvasive squamous cell carcinoma (stage IA1) with minimal invasion into deeper cell layers is the most treatable stage with the highest survival rates. This stage is treated with a cone biopsy or loop electrosurgical excision procedure (LEEP) or simple hysterectomy. Five-year survival rates are close to 100%. 10 Most treatments for cervical cancer cause side effects. Side effects may differ, depending on the type of treatment used and your age and overall health. Your doctor can talk to you about your treatment choices and the side effects associated with each treatment.
Home treatment measures may help relieve some common side effects of cancer treatment. For more information, see the Home Treatment section of this topic. If you have recently been diagnosed with cervical cancer, you may experience a wide variety of emotions in reaction to your diagnosis. Most women will feel some denial, anger, and grief. There is no "normal" or "right" way to react to a diagnosis of cancer. You can take steps, though, to manage your emotional reactions to learning that you have cervical cancer. Some women find that talking with family and friends is comforting, while others may need to spend time alone to understand their feelings about their disease. If your emotions are interfering with your ability to make decisions about your health and to move forward with your life, it is important to talk with your doctor. Your cancer treatment center may offer counseling services. You may also contact your local chapter of the American Cancer Society to help you find a support group. Talking with other women who have had similar feelings after a diagnosis such as yours can help you accept and deal with your disease. Treatment for pregnant womenRecommended treatments are the same for pregnant women as for nonpregnant women. Treatment for early stage IA cervical cancer may be delayed until after delivery if the pregnancy is in the third trimester . A vaginal delivery may be possible. 1 For all stages of cervical cancer, treatment will be managed by a team of doctors specializing in cancer and high-risk pregnancies. The baby does not appear to be affected by cervical cancer, but treatment for the cancer may cause problems such as an early delivery or even the loss of the baby. 11 Treatment will consider the recommendations for the specific stage of cancer, the development of the baby, and the mother's preferences. 1 What to think about during initial treatmentDepending on the extent (stage) of your cancer, surgery may be combined with radiation therapy and chemotherapy. Radiation or chemotherapy given after a surgery is called adjuvant therapy . Some women with cervical cancer may be interested in participating in research studies called clinical trials. Clinical trials are designed to find better ways to treat cancer patients and are based on the most up-to-date information. Women who do not want standard treatments or are not cured using standard treatments may want to participate in clinical trials. These are ongoing in most parts of the United States and in some other countries for all stages of cervical cancer. Cervical cancer progresses more rapidly, has higher recurrence rates, and has a poorer prognosis in women with human immunodeficiency virus (HIV) . For more information about specific cervical cancer treatments, see the topics:
Ongoing treatmentAfter initial treatment for cervical cancer , it is important to receive follow-up care. Your emotional reactions may continue throughout the course of your treatment depending on your prognosis, the treatment methods used, and your quality-of-life decisions. Your oncologist or gynecologic oncologist will schedule regular checkups that will include:
Follow-up tests that may be recommended by your oncologist include an abdominal and pelvic computed tomography (CT) scan to monitor whether cancer has spread to other organs in the abdomen or pelvis. If respiratory symptoms are present, a chest X-ray may be done to determine whether cancer has spread to the lungs. Treatment if the condition gets worseCervical cancer can return after treatment. About 35% of women with cervical cancer will have persistent or recurrent disease. 12 The chance that your cancer will return depends on the stage of the initial cancer: cancer found early is less likely to come back than cancer found at a later stage. If cancer returns after treatment, it is usually within 2 years of the first diagnosis. 10 Your long-term outcome (prognosis) for recurrent cervical cancer depends greatly on how much the cancer has spread when the recurrence is diagnosed. 10, 7
The goal of treatment of advanced-stage cervical cancer that has spread outside the pelvis is to control symptoms, reduce complications, and increase comfort ( palliative care ). It is not intended to cure the disease. Palliative care may include:
Complementary therapiesIn addition to conventional medical treatment, you may wish to try complementary therapies, such as:
Complementary therapies are not a substitute for the standard treatment recommended for cervical cancer. Before you try any of these therapies, discuss their possible benefits and side effects with your doctor. Let him or her know if you are already using any such therapies. For more information, see the topic Complementary Medicine. End-of-life issuesSome women with advanced-stage disease that is not curable may choose not to have cancer treatment because the time, costs, and side effects of treatment may be greater than the benefits. Making the decision about when to stop cancer treatment aimed at prolonging life and shift the focus to best supportive care can be difficult. For more information, see the topics: PreventionYou can treat early cervical cell changes (dysplasia), which can reduce your risk for cervical cancer . You can also reduce your risk factors for abnormal cell changes. Have regular Pap test screeningThe Pap test is the most effective screening test for cervical cancer. Pap tests done at regular intervals almost always detect cervical cell changes before the changes become cancerous. Regular screening for and treatment of cervical cell abnormalities can prevent the abnormal cell changes from developing into cancer. It is important to follow up with your doctor after any abnormal Pap test result. Quit smokingWomen who smoke have a higher risk of developing cervical cell changes that can lead to cervical cancer. 13, 4 The reason for this is not fully understood, but quitting smoking may decrease this risk. Not smoking has many other health benefits. Nonsmokers have a lower risk of other cancers and heart disease. Being around secondhand smoke may also increase your risk of developing cell changes that can lead to cervical cancer. 13, 4 VaccineAn HPV vaccine (What is a PDF document?) (Gardasil) protects against four types of HPV, which together cause most cases of cervical cancer and genital warts. Three shots are given over 6 months. Gardasil is recommended for girls 11 to 12 years old. The immunization is also recommended for females 13 to 26 years old who did not receive it when they were younger. It can be given to girls as young as 9 years old. Studies show that the vaccine is safe and works well to help prevent cervical cancer and genital warts. 14 For more information see: Reduce your risk of a sexually transmitted disease (STD)Sexually transmitted diseases (STDs) often cause abnormal Pap tests and can lead to other serious health problems. Preventing an STD is easier than treating an infection after it occurs. The most common cause of cervical cancer is infection with a high-risk type of the human papillomavirus (HPV) . Since the HPV virus may remain in body cells for life, abnormal cervical cell changes that cause cervical cancer can be the result of either you or your partner having had an HPV infection years earlier. HPV infection usually does not cause symptoms, so you or your partner may not be aware of a current or past HPV infection. To reduce your risk:
Not having sexual contact is the only certain way to prevent exposure to STDs. Sexually transmitted diseases such as human papillomavirus (HPV) can be spread to or from the genitals, anus, mouth, or throat during sexual activities. Home TreatmentDuring medical treatment for any stage of cervical cancer , you can use home treatment to help manage the side effects of cervical cancer or cancer treatment. Home treatment may be all that is needed to manage the following common problems. If your doctor has given you instructions or medicines to treat these symptoms, be sure to follow them. In general, healthy habits such as eating a balanced diet and getting enough sleep and exercise can help control your symptoms. Home treatment for:
Other issues that may arise include:
Many women with cervical cancer face emotional issues as a result of their disease or its treatment.
Not all forms of cancer or cancer treatment cause pain. If pain occurs, many options are available to relieve it. If your doctor has given you instructions or medicines to treat pain, be sure to follow them. Home treatment for pain such as a nonsteroidal anti-inflammatory drug (NSAID) or an alternative therapy like biofeedback may improve your physical and mental well-being. Be sure to discuss any home treatment you use for pain with your doctor. For more information on how to deal with pain from cancer or cancer treatment, see: Some women with advanced-stage disease may choose not to have treatment because the time, costs, and side effects of treatment may be greater than the benefits. Making the decision about when to stop medical treatment aimed at prolonging life and shift the focus to end-of-life care can be difficult. For more information, see the topics: MedicationsChemotherapy is used to shrink cervical cancer and decrease tumor growth. Chemotherapy may be used to treat later stages (stages II, III, and IV) of cervical cancer. It may be used alone or in combination with radiation (chemoradiation). Compared with radiation alone, chemoradiation improves survival. 9 It is usually used as the primary therapy or after a hysterectomy. Chemotherapy medicines may be taken by mouth (orally) or injected into a vein (intravenous, or IV). Chemotherapy is called a systemic treatment because the medicines enter the bloodstream and travel through the body to kill cancer cells. Extensive research and clinical trials have studied the different chemotherapy medicines used to treat cervical cancer. Some medicines are used routinely, and some are used in combination with others for greater effectiveness. Your oncologist will discuss and recommend chemotherapy treatment specific to your condition. Medication ChoicesThe most common chemotherapy medicines used for initial treatment or with radiation treatment in stage IIA, IIB, IIIA, IIIB, and IVA include: For advanced stage (stage IVB) cervical cancer or recurrent cervical cancer, the most common chemotherapy medicines used are: Topotecan has been approved to use with cisplatin for advanced cervical cancer. These drugs may be used when surgery or radiation cannot be done or are not likely to work. They can also be used for cervical cancer that has returned or spread to other organs. What To Think AboutMost chemotherapy will cause some side effects. Chemotherapy may be given after surgery to try to kill any cancer cells that may remain, which is called adjuvant therapy . Studies show that chemotherapy given at the same time as radiation treatment (chemoradiation) improves survival rates in stages IIB, IIIA, IIIB and IVA cervical cancer without significantly increasing the side effects of either treatment. Chemoradiation may also improve survival rates in stages IB and IIA for women with large tumors. 8, 3 Compared with radiation alone, chemoradiation improves survival. 9 It is usually used as the primary therapy or after a hysterectomy. Cisplatin is the medicine most often used in chemoradiation for cervical cancer. SurgerySurgery to remove cervical cancer may be an option when the cancer is confined to the cervix or uterus . The type of surgery performed depends on the location and extent of cervical cancer and your desire to be able to have children. Surgery ChoicesSurgery for very early stages of cervical cancer that preserves your ability to have children includes:
Surgery for most stages of cervical cancer does not preserve your ability to have children. Surgeries include:
What To Think AboutIf surgery is part of your treatment, you also may be given radiation therapy , chemotherapy , or combination chemoradiation. These treatments may be given before or after surgery to try to destroy any cancer cells that may remain. Radiation, chemotherapy, or chemoradiation given before a surgery to help control or reduce the size of the tumor is called neoadjuvant therapy . Using these therapies after a surgery when only microscopic areas of cancer may still be present is called adjuvant therapy . Compared with radiation alone, chemoradiation improves survival if it is used either before or after a hysterectomy. 9 Side effects from surgery can include difficulty with urination or problems with bowel habits, such as constipation or diarrhea. Your ability to have or enjoy sexual intercourse may also be affected. Other TreatmentRadiation therapy is the standard treatment for certain stages of cervical cancer and often is used in combination with surgery. Radiation therapy is the use of high-energy X-rays to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external radiation therapy) or from radiation material (radioisotopes) in thin plastic tubes inserted through the vagina into the cervical area where the cancer cells are found (intracavitary brachytherapy). The two forms of brachytherapy used to treat cervical cancer include low-dose-rate (LDR) brachytherapy and high-dose-rate (HDR) brachytherapy. LDR brachytherapy has been used the most in the past, but HDR brachytherapy takes less time and can be done on an outpatient basis. Both LDR and HDR appear to work about the same. 16 Studies show that chemotherapy given at the same time as radiation treatment (chemoradiation) improves survival rates in stages IIB, IIIA, IIIB and IVA cervical cancer without significantly increasing the side effects of either treatment. Chemoradiation may also improve survival rates in stages IB and IIA for women with large tumors. 8, 3 Compared with radiation alone, chemoradiation improves survival. 9 It is usually used as the primary therapy or after a hysterectomy. What to think aboutRadiation may cause many side effects, including diarrhea and irritation of the bladder (radiation cystitis). Your ability to have or enjoy sexual intercourse may also be affected because radiation may cause changes to the cells lining the vagina (mucosa), making intercourse difficult or painful. A series of vaginal dilators, starting with a small one and progressing to a larger size, may be used after radiation therapy. Using the dilators can make the vaginal opening larger and help make sex less difficult or painful. Radiation to treat cervical cancer may thin the bone and increase the risk of fractures in the pelvic area, including hip fractures. You can take steps to prevent thinning of the bone ( osteoporosis ), such as getting enough calcium and vitamin D. Also, try to prevent falls, which can lead to fractures. 17 For more information, see the topic Osteoporosis. Radiation therapy may also be used to manage the symptoms that occur with incurable cervical cancer: this is called palliative care . Other Treatment ChoicesIn addition to conventional medical treatment for cervical cancer , you may wish to try complementary therapies, such as:
Complementary therapies are not a substitute for the standard treatment recommended for cervical cancer. Before you try any of these therapies, discuss their possible benefits and side effects with your doctor. Let him or her know if you are already using any such therapies. For more information, see the topic Complementary Medicine. What To Think AboutThe combination of conventional medical treatment and complementary medicine is an approach sometimes termed integrative medicine, in which conventional and complementary therapies work together for the best outcome. Complementary therapies are not a substitute for the standard treatment recommended for cervical cancer. Other Places To Get HelpOrganizations
