Mostly brown stool, but there's black mixed with it. apparently this is not normal. could it mean blood? black is all over stool. normal size. cancer?

Stool color: Stool that appears dark can be caused by a number of possibilities. Blood, drug intake, iron, certain food types, food coloring, are only a few of the possible causes. Blood in stool may be suspect for cancer but needs lab testing in order to confirm.
