No: Most common cause of bleeding with stool is hemorrhoids. One cannot really tell the cause of bleeding by history alone and people with recurrent bleeding need to have colonoscopy to ensure they do not have any cancer.

It depends: Rectal bleeding can be caused from hemorrhoids(commonest cause) or by colon cancer. So an examination is required to find the exact cause. Any rectal bleeding is a signal to go to your doctor for a complete examination to find the cause and treat it accordingly.

No true correlation: Stool guaiac to define blood in stool of little value since many tumors do not bleed especially those on the rt. side where bowel content is mostly liquid and will not extract blood from a tumor. In addition internal hemorrhoids can bleed and as such no correlation to malignancy. Colonoscopy every 5 yrs looking for bowel lesions is the most effective screening test at the present time.

Many things.: There can be many reasons for this. It may only be hemorrhoids, or anal fissure. These should be considered before cancer. Colorectal cancer of the left side or sigmoid colon can present with bleeding also, but other symptoms are present, like altered bowel habits, and abdominal pain. A fecal occult blood test is done in the standard work-up for colon cancer. Start by seeing your doctor.

Not always: Rectal bleeding can happen in almost 40-50% cases. Other symptoms that can happen include abdominal pain , change in bowel habits, weakness , anemia without other gastrointestinal symptoms, weight loss. Sometimes, colon cancer also can happen without having any significant symptoms-but is found during colonoscopy. Colonoscopy is very important screening test. Do not wait until you see bleeding.
