Cancers can occur in any part of the female reproductive system—the vulva, vagina, cervix, uterus, fallopian tubes, or ovaries. These cancers are called gynecologic cancers.

The most common gynecologic cancer in the United States is cancer of the uterus Cancer of the Uterus The most common type of cancer of the uterus develops in the lining of the uterus (endometrium) and is called endometrial cancer.

The cervix is the lower part of the uterus, but cancer of the cervix is usually called cervical cancer, and cancer of the body of the uterus is called uterine cancer (or endometrial cancer). Cervical cancer is less common in high-income than in middle- or low-income countries because, in high-income countries, screening for cervical cancer Screening for Cervical Cancer Sometimes doctors recommend screening tests, which are tests that are done to look for disorders in people who have no symptoms.

Gynecologic cancers can spread in the following ways:

  • Directly invade nearby tissues and organs

  • Spread (metastasize) through the lymphatic vessels and lymph nodes (lymphatic system) or through the bloodstream to distant parts of the body

Diagnosis

  • Regular pelvic examinations

  • Biopsy

Such examinations can sometimes prevent cancer by detecting precancerous changes (dysplasia) before they become cancer. Regular pelvic examinations can also detect cancers of the vagina and vulva. However, cancers of the ovaries, uterus, and fallopian tubes are not easy for doctors to detect during a pelvic examination.

If cancer is suspected, a biopsy Biopsy Sometimes doctors recommend screening tests, which are tests that are done to look for disorders in people who have no symptoms. If women have symptoms related to the reproductive system (gynecologic... read more Biopsy can confirm or rule out the diagnosis. A sample of tissue from the affected organ is removed, examined under a microscope, and analyzed. For some cancers, such as ovarian cancer, surgery must usually be done to make the diagnosis.

Staging

If cancer is diagnosed, one or more procedures may be done to determine the stage of the cancer. The stage is based on how large the cancer is and how far it has spread. Some commonly used procedures include ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), chest x-rays, and positive emission tomography Positron Emission Tomography (PET) Positron emission tomography (PET) is a type of radionuclide scanning. A radionuclide is a radioactive form of an element, which means it is an unstable atom that becomes more stable by releasing... read more Positron Emission Tomography (PET) (PET). Doctors often determine the stage of cancer after they remove the cancer and biopsy the surrounding tissues, including lymph nodes.

Staging a cancer helps doctors choose the best treatment.

For all gynecologic cancers, stages range from I (the earliest) to IV (advanced). For most cancers, further distinctions, designated by letters of the alphabet, are made within stages.

Treatment

  • Surgical removal

  • Sometimes radiation therapy and/or chemotherapy

Cancer treatment may include surgical removal, radiation therapy, and chemotherapy, depending on the type and stage of cancer.

When cancer is first diagnosed, the main goal of treatment is to remove or stop the growth of the cancer if possible (through a single treatment or through a combination of surgery, radiation therapy, and chemotherapy).

Chemotherapy is usually the most effective way to treat any cancer cells that have spread beyond the original site. Using combinations of chemotherapy drugs may help eliminate the original cancer and eliminate cancer cells elsewhere in the body, even when there is no sign of those cells.

Radiation therapy may be external (using a large machine) or internal (using radioactive implants placed directly on the cancer) or both. External radiation therapy is usually given several days a week for several weeks. Internal radiation therapy involves staying in the hospital for several days while the implants are in place.

Chemotherapy may be given by injection, by mouth, or through a catheter inserted into the abdomen (intraperitoneally). How often chemotherapy is given depends on the type of cancer and the type of chemotherapy drug used. Sometimes women have to remain at the hospital while they receive chemotherapy.

When a gynecologic cancer is very advanced and a cure is not possible, radiation therapy or chemotherapy may still be recommended to reduce the size of the cancer or its metastases and to relieve pain and other symptoms.

Appropriate drugs can be used to relieve the anxiety and pain commonly experienced by people with incurable cancer.
