Question: What are the stages of Endometrial Cancer ?

Answer: Key Points
                    - After endometrial cancer has been diagnosed, tests are done to find out if cancer cells have spread within the uterus or to other parts of the body.    - There are three ways that cancer spreads in the body.    - Cancer may spread from where it began to other parts of the body.    - The following stages are used for endometrial cancer:         - Stage I     - Stage II     - Stage III     - Stage IV        - Endometrial cancer may be grouped for treatment as follows:         - Low-risk endometrial cancer     - High-risk endometrial cancer
                
                
                    After endometrial cancer has been diagnosed, tests are done to find out if cancer cells have spread within the uterus or to other parts of the body.
                    The process used to find out whether the cancer has spread within the uterus or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. Certain tests and procedures are used in the staging process. A hysterectomy (an operation in which the uterus is removed) will usually be done to treat endometrial cancer. Tissue samples are taken from the area around the uterus and checked under a microscope for signs of cancer to help find out whether the cancer has spread.   The following procedures may be used in the staging process:          -   Pelvic exam : An exam of the vagina, cervix, uterus, fallopian tubes, ovaries, and rectum. A speculum is inserted into the vagina and the doctor or nurse looks at the vagina and cervix for signs of disease. A Pap test of the cervix is usually done. The doctor or nurse also inserts one or two lubricated, gloved fingers of one hand into the vagina and places the other hand over the lower abdomen to feel the size, shape, and position of the uterus and ovaries. The doctor or nurse also inserts a lubricated, gloved finger into the rectum to feel for lumps or abnormal areas.    -   Chest x-ray : An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.     -   CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.     -   MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).    -   PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.    -   Lymph node dissection : A surgical procedure in which the lymph nodes are removed from the pelvic area and a sample of tissue is checked under a microscope for signs of cancer. This procedure is also called lymphadenectomy.
                
                
                    There are three ways that cancer spreads in the body.
                    Cancer can spread through tissue, the lymph system, and the blood:         - Tissue. The cancer spreads from where it began by growing into nearby areas.     - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.     - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.
                
                
                    Cancer may spread from where it began to other parts of the body.
                    When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood.         - Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body.    - Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body.        The metastatic tumor is the same type of cancer as the primary tumor. For example, if endometrial cancer spreads to the lung, the cancer cells in the lung are actually endometrial cancer cells. The disease is metastatic endometrial cancer, not lung cancer.
                
                
                    The following stages are used for endometrial cancer:
                    Stage I     In stage I, cancer is found in the uterus only. Stage I is divided into stages IA and IB, based on how far the cancer has spread.             -  Stage IA: Cancer is in the endometrium only or less than halfway through the myometrium (muscle layer of the uterus).     -  Stage IB: Cancer has spread halfway or more into the myometrium.              Stage II     In stage II, cancer has spread into connective tissue of the cervix, but has not spread outside the uterus.        Stage III    In stage III, cancer has spread beyond the uterus and cervix, but has not spread beyond the pelvis. Stage III is divided into stages IIIA, IIIB, and IIIC, based on how far the cancer has spread within the pelvis.            -  Stage IIIA: Cancer has spread to the outer layer of the uterus and/or to the fallopian tubes, ovaries, and ligaments of the uterus.      -  Stage IIIB: Cancer has spread to the vagina and/or to the parametrium (connective tissue and fat around the uterus).     -  Stage IIIC: Cancer has spread to lymph nodes in the pelvis and/or around the aorta (largest artery in the body, which carries blood away from the heart).              Stage IV    In stage IV, cancer has spread beyond the pelvis. Stage IV is divided into stages IVA and IVB, based on how far the cancer has spread.            -  Stage IVA: Cancer has spread to the bladder and/or bowel wall.     -  Stage IVB: Cancer has spread to other parts of the body beyond the pelvis, including the abdomen and/or lymph nodes in the groin.
                
                
                    Endometrial cancer may be grouped for treatment as follows:
                    Low-risk endometrial cancer     Grades 1 and 2 tumors are usually considered low-risk. They usually do not spread to other parts of the body.       High-risk endometrial cancer     Grade 3 tumors are considered high-risk. They often spread to other parts of the body. Uterine papillary serous, clear cell, and carcinosarcoma are three subtypes of endometrial cancer that are considered grade 3.
