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.

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

Regular pelvic examinations can also detect early cancers of the vagina and vulva.

A sample of tissue from the affected organ is removed, examined under a microscope, and analyzed.
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 
(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 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.
