Colon cancer, also known as colorectal cancer, is a malignant growth that begins in the cells of the colon or rectum. It is the third most common type of cancer in the United States. Early detection is crucial for successful treatment, and awareness of the symptoms can be life-saving. This article aims to shed light on the common symptoms associated with colon cancer.
Physical Symptoms
Physical symptoms of colon cancer can be quite diverse and vary depending on the location and size of the cancer. These symptoms can often be mistaken for less serious conditions, which can delay diagnosis. The most common symptom is a change in bowel habits. This may include diarrhea, constipation, or change in the consistency of the stool that lasts longer than four weeks. Rectal bleeding or finding blood in the stool is another common sign. Cramping or abdominal pain, persistent bloating, and feeling that the bowel doesn't completely empty can also indicate colon cancer. Unexplained weight loss is another symptom that should not be overlooked. The body might be using up more energy to fight off the cancer, leading to weight loss even if the person's diet hasn't changed.
Systemic Symptoms
In addition to the physical symptoms, colon cancer can also present systemic symptoms. These are symptoms that affect the whole body and not just the colon. Fatigue or weakness is a common systemic symptom of colon cancer. It can be due to anemia caused by a slow, chronic blood loss in the colon, resulting from the cancer. Another systemic symptom is unexplained loss of appetite. This symptom, coupled with unexplained weight loss, should raise a concern. In some cases, jaundice, which is characterized by yellowing of the skin and eyes, can be a symptom of colon cancer. It is usually a sign that the cancer has spread to the liver.
