Symptoms of the last stages of ovarian cancer include severe pain in the abdomen and pelvic area, according to Healthline. Large ovarian cancer tumors can block the intestine, causing constipation, bloating, nausea, vomiting and malaise.
Sepsis can also accompany the constipation, says Healthline. Sepsis is a complication of an infection, says Mayo Clinic. If left untreated, it causes such severe inflammation that organ systems throughout the body begin to fail.
Since ovarian cancer can block the ureters that drain the kidneys, kidney pain is also common in the last stage of ovarian cancer, according to Healthline. At the same time, the patient feels a frequent urge to urinate as the cancer presses against her bladder. If the kidneys are blocked for too long, they can become damaged. Surgery may be needed to correct this problem.
Unremitting bloating and swelling are another sign of late-stage ovarian cancer, states Healthline. At the same time, the patient experiences rapid and otherwise unexplained weight loss. Working with a doctor to maintain a healthy weight is critical.
A condition called ascites is also a symptom of the last stage ovarian cancer, according to Healthline. Ascites is the buildup of fluid in the abdomen, and it can result in painful swelling and bloating.
