Not necessarily: Some lesion could have developed over the period of a year. Some lesions bleed intermittently and that is why it is recommended that three samples be tested. Blood in the stool in an adult usually warrants a colonoscopy to find the cause of bleeding and to rule out colon cancer.
Wish you good health!.
