Tests and procedures used to diagnose endometrial cancer include:
- Pelvic examination. During a pelvic exam, your doctor carefully inspects the outer portion of your genitals (vulva), and then inserts two fingers of one hand into your vagina and simultaneously presses the other hand on your abdomen to feel your uterus and ovaries. He or she also inserts a device called a speculum into your vagina. The speculum opens your vagina so that your doctor can view your vagina and cervix for abnormalities.
- Using sound waves to create a picture of your uterus. Your doctor may recommend a transvaginal ultrasound to look at the thickness and texture of the endometrium and help rule out other conditions. In this procedure, a wand-like device (transducer) is inserted into your vagina. The transducer uses sound waves to create a video image of your uterus. This test helps your doctor look for abnormalities in your uterine lining.
- Using a scope to examine your endometrium. During a hysteroscopy, your doctor inserts a thin, flexible, lighted tube (hysteroscope) through your vagina and cervix into your uterus. A lens on the hysteroscope allows your doctor to examine the inside of your uterus and the endometrium.
- Removing a sample of tissue for testing. To get a sample of cells from inside your uterus, you'll likely undergo an endometrial biopsy. This involves removing tissue from your uterine lining for laboratory analysis. Endometrial biopsy may be done in your doctor's office and usually doesn't require anesthesia.
- Performing surgery to remove tissue for testing. If enough tissue can't be obtained during a biopsy or if the biopsy results are unclear, you'll likely need to undergo a procedure called dilation and curettage (D&C). During D&C, tissue is scraped from the lining of your uterus and examined under a microscope for cancer cells.
If endometrial cancer is found, you'll likely be referred to a doctor who specializes in treating cancers involving the female reproductive system (gynecologic oncologist).
Staging endometrial cancer
Once your cancer has been diagnosed, your doctor works to determine the extent (stage) of your cancer. Tests used to determine your cancer's stage may include a chest X-ray, a computerized tomography (CT) scan, positron emission tomography (PET) scan and blood tests. The final determination of your cancer's stage may not be made until after you undergo surgery to treat your cancer.
Stages of endometrial cancer include:
May. 14, 2013
- Stage I cancer is found only in your uterus.
- Stage II cancer is present in both the uterus and cervix.
- Stage III cancer has spread beyond the uterus, but hasn't reached the rectum and bladder. The pelvic area lymph nodes may be involved.
- Stage IV cancer has spread past the pelvic region and can affect the bladder, rectum and more-distant parts of your body.
