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

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 medical imaging called radionuclide scanning. By detecting radiation after a radioactive material is administered, PET creates images that can... 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 of Female Reproductive System Cancers
Usually, 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.
Chemotherapy is usually the most effective way to treat any cancer cells that have spread beyond the original site. Chemotherapy may be given by injection, by mouth, or through a catheter inserted into the abdomen (intraperitoneally).
Radiation therapy is usually given if a tumor has spread to surrounding tissues that are next to the original tumor, such as spread of a tumor of the uterus to the bladder.
For some gynecologic cancers, hormone therapy or hormone blockers are given as additional treatment, usually after surgery, chemotherapy, and/or radiation therapy have been completed. Hormone therapy works by stimulating or blocking hormone receptors to stop growth of any tumor cells that have spread from the original site.
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.
