For several months, I have been passing flat or pencil thin stools. I do on occasion see blood. I also notice that after passing the thin/flat stools, I will then pass some stool that I think looks like pencil shavings. I have had problems in the recent months with some constipation and I do at times feel bloated. I also notice that I also have anal pain and some burning in that area. My Dr. did a digital rectal exam and told me that I had some "nodules" in the anal area and recommends that I see a colorectal surgeon. Is anyone else experiencing these symptoms? Could this be cancer?
