Symptoms of Colon Cancer can vary widely and may not be present in the early stages of the disease. Common symptoms include changes in bowel habits such as diarrhea, constipation, or a change in the consistency of stool that lasts for more than a few days. Patients might also notice rectal bleeding or blood in the stool, which can be a sign of cancer but can also be caused by other conditions like hemorrhoids. Abdominal discomfort, such as cramps, gas, or pain, and a feeling that the bowel does not empty completely, are also frequent symptoms. Additionally, unexplained weight loss, weakness, and fatigue could be signs of colon cancer as these symptoms can arise from the cancer consuming the body's nutrients and energy.

These Symptoms can often be attributed to less serious conditions, but it is crucial to consult a healthcare provider if they persist, as early detection significantly increases the chances of successful treatment. Regular screening is especially important because symptoms typically appear only after the cancer has grown or spread. Therefore, recognizing these signs and getting screened can lead to early diagnosis when treatment is more likely to be successful.
