I have just read about your mom. I have just registered here. My mom is 87 years old and she was diagnosed too with colon cancer stage four. A lot of American doctors do not want to touch elderly patients. They get scared, plus we live in a society where everyone suits each other it makes it difficult to get proper care. My mother eventually had the surgery and it went all right, no need for a bad or a blood transfusion. Her doctor was from India and he was an angel. We trusted him and he did fine. He put staples in her colon. He removed the affected area and joined in with staples the two good areas of the intestine. It was a sigmoid resection. In 7 months or so she got a tumor in her liver though which they treated with a Y90 chemoembolization. It used a catheter to inject a radioactive chemical directed only at the tumor. The procedure went perfect. It destroyed it completely. Her doctor told me that it has been around for about 10 years. She is doing all right, every 4 months or so she has to go for a CT scan to see how things are going. If you read this message I hope it gives you hope because there are treatments out there. I hope your mom is okay. My mother got the treatment and the follow up care at the New York Hospital Cornell in New York City, the best in the field. I have also been taking her to Sloan Kettering Cancer Center which is across the stress just for a second opinion and to talk more about it. God bless your mom.
