Some of the most common include persistent changes in bowel habits—such as prolonged episodes of diarrhea or constipation with no obvious explanation. Blood in the stool is another symptom that should be evaluated immediately by a healthcare professional.
Many people also experience frequent abdominal pain or a constant feeling of discomfort that interferes with daily activities. Another common indicator is unexplained weight loss, often accompanied by excessive fatigue or significantly low iron levels, which can lead to anemia. Even though these signs don’t always point directly to colorectal cancer, they deserve attention because they may signal that something in the body isn’t functioning as it should.
