Colorectal Cancer

[Guest]

I recently had x-rays taken by my chiropractor He said he was going to get a second opinion as he always does (I assumed it was regarding my spine).

The Chiropractor pointed out a large portion of fecal material in my upper colon. The material was dark and similar to a picture of cancer in the colon appearing as a dark mass which I viewed in the AMA Family Medical Guide.

My question is:

Is it normal for large portion of fecal material to appear just in the upper colon.

Ignorant and appreciative of any help you can give me.
