Is there a big chance of cancer in stool occult blood positive?

If

the patient has positive stool occult blood results, but the body does not appear uncomfortable symptoms, and imaging examination, such as CT, magnetic resonance imaging, etc., found that there is no local space-occupying lesion, or space-occupying lesion shape rules, and clear boundaries with surrounding tissues, usually the probability of cancer is low. If the patient has positive stool occult blood, abdominal pain, mass, change of defecation habits and other symptoms, and imaging examination shows space-occupying lesions, unclear boundary between lesions and surrounding areas, irregular shape and abundant blood flow signals, the probability of cancer is greater.
