Stool testing

Hi. Not posted before but visit lots. I have been having poop issues for a few months now and I am having to do a lot of stool samples for testing. Over last 4 or 5 month my stools have become very Orangey in colour and sometimes a reddish brown that make an oily film on the water. Sometimes loose and fluffy sometimes formed, I also found out that most people’s poop does not float like mine always seam to do. So my HA is in full swing with me having everything from pancreatic cancer, bowel cancer, tumor in my small intestines all the bad stuff and coupled with constant lower back pain. I am finding it hard to find a reason for my symptoms that’s not really scary. Sorry if TMI but really worried
