Fluid in the endometrial cavity may be a sign of cancer, but it may have another cause, states Medical-Base.com. A doctor must evaluate all of a patient's symptoms and perform tests to determine the cause.
Causes of fluid in the endometrial cavity include fibroids, polyps and infections, according to Medical-Base.com. The possibility that cancer is the cause is greater if the fluid occurs in conjunction with vaginal bleeding between periods, episodes of heavy bleeding that last for several days or more, abdominal or pelvic pain, and white or clear vaginal discharge, reports The Doctor Will See You Now. A doctor may order tests such as a transvaginal ultrasound, a hysteroscopy, a biopsy of the lining of the uterus and a dilation and curettage.
Women who are post-menopausal and had hormone therapy without progesterone, women who are pre-menopausal with a history of missed periods, and women who have Lynch or Cowden syndrome have a higher risk for endometrial cancer, explains The Doctor Will See You Now. Women with a cancer diagnosis may undergo blood tests to measure liver and kidney function and X-rays or scans to determine if the cancer has spread to any other part of the body. Treatment options include chemotherapy, hormone therapy, radiation and surgery.
