It’s one frightening experience: You wipe yourself after pooping, glance at the toilet paper and see red or pink smeared in with the poop stain.

Your heart races; your breathing stops; your eyes don’t blink as your mouth hangs open. You wonder if it’s colon cancer.

“As a gastroenterologist, I take all rectal bleeding seriously, but there are some elements in the patient’s history that point more in the direction of a hemorrhoid bleeding as opposed to a lesion in the colon,” says Dr. Caterina Oneto, MD, with Concorde Gastroenterology, and Clinical Assistant Professor within the NYU Division of Gastroenterology.

Dr. Oneto continues, “Blood ‘just on the toilet paper’ is one of them. Still, always see your doctor when you experience any form of rectal bleeding.”

A lesion in the large colon that can cause blood to come out with stools (and make its way to the tissue paper) may be an ulcer, a polyp or a malignant tumor.

A pinkish or reddish smear on the toilet paper may also be from an irritated (and bleeding) skin tag at the anal opening.

Other Causes of Blood on the Toilet Paper but No Sign of It in Your Poops

When you wipe, the tissue paper not only makes contact with the anal opening, but also with the urethral and (for women, of course) vaginal opening – assuming that you wipe thoroughly: from back to front.

A problem with the urethra, vagina, cervix or uterus can cause blood to appear on the tissue paper but not in the stools you see in the toilet bowl.

If a colonoscopy has ruled out a lesion in the colon, you are still not in the clear.

You need to get your urethra examined, and if you’re a woman, you need an internal pelvic exam as a start.

It could just be a coincidence that the first time you saw blood on the toilet paper was when you had a bowel movement.

This doesn’t mean the blood is directly connected to having a bowel movement (e.g., irritation of a hemorrhoid), but more so because your wiping made contact with blood that was near the urethral or vaginal entrance.
