A 82 year old female with a history of uterine cancer was admitted to the hospital. At that time, she went through hysterectomy, followed by radiation. Since then, she has been relatively healthy until now. She has developed abdominal pain, fatigue, and loss of energy. All tests were negative. Occasional vomitting developed, and weight loss occurred.
Still all tests were negative. A colonscopy was performed, and a malignant tumor was located. Only a small portion of the tumor was able to be removed. A colonstomy was created, and the patient was able to eat better and gain some weight. Chemotherapy was not an option.
