Pediatrics/Blood in toilet
I have a hx of rectal cancer diagnosed at age 42 but tested negative for genetic causes. I now have a 15 year old with rectal bleeding. He has had this on and off for a year or so, before was only with constipation and when he didn't go for a couple of days, then he would say it hurt so bad to go so docs assumed hemmorhoids or fissure. xray was negative except for a lot of stool. hgb was normal. then the constipation stopped, he had surgery for inguinal hernia and still no constipation even after using narcotics post surgery.
now he is 2 weeks with bleeding after every time. He said it is sometimes bright red, sometimes a little darker red. Is in toilet bowl and on toilet paper. Brought him to doc again who did a quick digital exam and looked around and he said he didn't see anything obvious, so because of my history they are sending us to a pediatric gastroenterologist for colonoscopy. We cannot get in for a few weeks and we sit here in limbo worrying. What are the odds this could be a polyp or cancer in a 15 year old. he does not have mucous, abdominal pain,diarrhea or any thing suggestive of inflammation or other and with no obvious hemorrhoids although we do have a family history of crohns with my mom ,aunt, and cousin with it. I am concerned.
Unexplained rectal bleeding in kids this age is seldom due to cancer. It is far more likely this is a polyp or possibly something like Crohns disease. A good exam by a skilled peds gastroenterologist should discover the cause. Cancer would be at the bottom of the list, although possible and a bit more likely due to your history.
Good luck, and feedback re this cause to me is always appreciated, Dr. Olson
