Colon Cancer: Signs & Symptoms

Colon cancer, also known as colorectal cancer, is one of the most common types of cancer that affects both men and women. It is a type of cancer that begins in the colon, which is part of the large intestine. Colon cancer can be silent, which means it can develop without any noticeable symptoms. However, early detection is crucial in treating colon cancer.


Change in bowel habits:

One of the most common signs of colon cancer is a change in bowel habits. You may experience persistent diarrhoea or constipation, or a change in the consistency of your stool. You may also feel the need to have a bowel movement more frequently than usual. If you notice any of these symptoms, it's important to speak with your doctor.

Abdominal pain and discomfort:

Colon cancer can cause abdominal pain and discomfort, which may range from mild to severe. You may feel cramping or bloating, or a general feeling of discomfort in your abdomen. These symptoms may be accompanied by nausea or vomiting.

Blood in your stool:

Blood in your stool can be a sign of colon cancer, especially if it is bright red or dark in colour. However, blood in your stool can also be caused by haemorrhoids or other conditions. If you notice blood in your stool, it's important to speak with your doctor.

Unexplained weight loss:

If you haven't been trying to lose weight but are losing weight without explanation, it could be a sign of colon cancer. Unexplained weight loss can be a symptom of many types of cancer, including colon cancer.

Fatigue and weakness:

Colon cancer can cause fatigue and weakness, which may be due to the disease itself or the treatment. You may feel tired all the time, even after getting enough sleep. If you experience persistent fatigue and weakness, it's important to speak with your doctor.

If you experience any of the symptoms mentioned above, it's important to speak with your doctor.
