Mom has been in ICU since Sunday night. Apparently she was bleeding internally and lost 2/3 of her blood. She required 4 pints to stabilize her. So far, so good.
They suspect, but still aren't sure, if the problem is from the colon cancer or some other source. They won't know until a CT scan and/or colonoscopy is performed, which should be today. I suspect it's the cancer. As her physician said, when you know there's a horse in the room why look for a zebra.
I saw her last night during evening visiting hours, and she looked much better and was pretty feisty. That, in itself, is a sense of relief. I can only pray at this point that things turn out for the best and that she's spared as much as pain and discomfort as possible.
