Cervical Cancer


Most often, treatment for cervical cancer involves surgery and radiation therapy. Sometimes, chemotherapy or biological therapy is used in the treatment of cervical cancer. Patients are often treated by a team of specialists. The team may include gynecologic oncologists and radiation oncologists. The doctors may decide to use one treatment method or a combination of methods. Some patients take part in a clinical trial (research study) using new treatment methods. Such studies are designed to improve cancer treatment.

Surgery is local therapy to remove abnormal tissue in or near the cervix. If the cervical cancer is only on the surface of the cervix, the doctor may destroy the cancerous cells in ways similar to the methods used to treat precancerous lesions. If the cervical cancer has invaded deeper layers of the cervix but has not spread beyond the cervix, the doctor may perform an operation to remove the tumor but leave the uterus and the ovaries. In other cases, however, a woman may need to have a hysterectomy or may choose to have this surgery, especially if she is not planning to have children in the future. In this procedure, the doctor removes the entire uterus, including the cervix; sometimes the ovaries and fallopian tubes also are removed. In addition, the doctor may remove lymph nodes near the uterus to learn whether the cancer has spread to these organs.

Radiation for Cervical Cancer (also called radiotherapy) uses high-energy rays to damage cancer cells and stop them from growing. Like surgery, radiation therapy is local therapy; the radiation can affect cancer cells only in the treated area. The radiation may come from a large machine (external radiation) or from radioactive materials placed directly into the cervix (implant radiation). Some patients receive both types of radiation therapy.

A woman receiving external radiation therapy goes to the hospital or clinic each day for treatment. Usually treatments are given 5 days a week for 5 to 6 weeks. At the end of that time, the tumor site very often gets an extra "boost" of radiation.

For internal or implant radiation, a capsule containing radioactive material is placed directly in the cervix. The implant puts cancer-killing rays close to the tumor while sparing most of the healthy tissue around it. It is usually left in place for 1 to 3 days, and the treatment may be repeated several times over the course of 1 to 2 weeks. The patient stays in the hospital while the implants are in place.

Cervical Cancer Chemotherapy is the use of drugs to kill cancer cells. It is most often used when cervical cancer has spread to other parts of the body. The doctor may use just one drug or a combination of drugs. Anticancer drugs used in the treatment of cervical cancer may be given by injection into a vein or by mouth. Either way, chemotherapy is systemic treatment, meaning that the drugs flow through the body in the bloodstream.

When used in cervical cancer treatment, chemotherapy is given in cycles: a treatment period followed by a recovery period, then another treatment period, and so on. Most patients have chemotherapy as an outpatient (at the hospital, at the doctor's office, or at home). Depending on which drugs are given and the woman's general health, however, she may need to stay in the hospital during her cervical cancer treatment.

Biological therapy for Cervical Cancer is a cervical cancer treatment using substances to improve the way the body's immune system fights disease. It may be used to treat cancer that has spread from the cervix to other parts of the body. Interferon is the most common form of biological therapy for this disease; it may be used in combination with chemotherapy. Most patients who receive interferon as a form of cervical cancer are treated as outpatients.

Treatment for Precancerous Conditions

Treatment for a precancerous lesion of the cervix depends on a number of factors. These factors include whether the lesion is low or high grade, whether the woman wants to have children in the future, the woman's age and general health, and the preference of the woman and her doctor. A woman with a low-grade lesion may not need further treatment, especially if the abnormal area was completely removed during biopsy, but she should have a Pap test and pelvic exam regularly. When a precancerous lesion requires treatment, the doctor may use cryosurgery (freezing), cauterization (burning, also called diathermy), or laser surgery to destroy the abnormal area without harming nearby healthy tissue. The doctor also can remove the abnormal tissue by LEEP or conization. Treatment for precancerous lesions may cause cramping or other pain, bleeding, or a watery discharge.

In some cases, a woman may have a hysterectomy, particularly if abnormal cells are found inside the opening of the cervix. This surgery is more likely to be done when the woman does not want to have children in the future.
