Today i found some really small dots of blood in my stool so i'm really worried. is it colon cancer?

Need to be checked: Any blood in the stool is cause for concern and should prompt your seeing a physician soon. Hopefully, it is simply a bleeding hemorrhoid, fissure or other benign cause but malignancy must be ruled out. A proctoscopy or flexible sigmoidoscopy might be performed as an office procedure but if negative, a full colonoscopy must be performed to be sure there is not a colon polyp or cancer.
