One of the silent signs of colon cancer is rectal bleeding. Affected people might notice red blood either the stool or on the toilet paper after they wipe. Or the poop may become dark because of the blood that has been digested in the GI tract.
The cause behind rectal bleeding could also be anal fissures or hemorrhoids. In any case, you should visit a doctor as soon as you notice blood in the toilet.
