I agree with Paul, this seems backward. I had a tumor in my colon, the pain was unbearable towards the end. (while waiting for surgery) I was going to the bathroom about 15 times a day, and the toilet looked like a murder scene. When I got a CT scan I was shocked to see that I had a lot of stool backed up. That was from the tumor not allowing everything to pass. After my surgery (very successful) I had 6 rounds of Folfox chemo. Did your Brother get a mediport put in his chest for the chemo? What Paul said is very important: "I hope you are dealing only with accredited cancer centers, not general hospitals or clinics."
