Blood in the stool accompanied with black or dark stool are often signs of colon or rectal cancer. Cervical cancer can cause vaginal bleeding. Furthermore, coughing up blood may be a sign of lung cancer. Bleeding can occur early in the early as well as advanced stages of cancer.
5. Bowel and bladder function changes
Be aware of any changes in the size and color of the stool as it may be a sign of colon cancer. Furthermore, feeling pain and discomfort while urinating or seeing blood is not normal. Don’t be embarrassed to tell your doctor of these changes.
