Hi, my husband has been diagnosed with colon cancer. He had a portion of his colon removed in Nov 13 and went for 3 sessions of chemo, his count spiked and was operated again. Another part of his colon was removed, (no stoma), together with apportion of his small intestine and a stomach muscle as well as part of his stomach/abdominal lining?. They also cleaned around his pancreas. He has now had a port inserted and will begin new chemo on Monday. he vomits a lot of fluids about every hour, (up to 2 glasses). the contents changes between brown and yellow water. Please tell me what is happening.
