Colon cancer is one of the most common types of
cancer, and early detection plays a critical role in successful treatment. In India, as per the Indian Council of Medical Research (ICMR), the annual incidence rates for colon cancer and rectal
cancer in men are 4.4 and 4.1 per 100000, respectively, with colon cancer ranking as the 8th most common among men.
The tricky part is that its symptoms can often be mistaken for other less serious conditions, such as digestive issues or haemorrhoids. Here are six common symptoms of colon cancer that everyone should be aware of.
Changes in Bowel Habits
A noticeable shift in bowel habits is often an early sign of colon cancer. This could mean frequent diarrhoea, constipation, or even alternating between the two. If these changes persist for more than a few weeks and don’t seem to be linked to dietary changes or stress, it’s a good idea to consult a healthcare professional.
Blood in the Stool
One of the more alarming symptoms is seeing blood in your stool. This could appear as bright red streaks or darker, tar-like stools. While blood in the stool can sometimes result from hemorrhoids or anal fissures, it can also be an indicator of colon cancer, especially if it’s accompanied by other symptoms like fatigue or weight loss. Experts suggest that any persistent rectal bleeding should be evaluated by a doctor immediately.
Unexplained Weight Loss
Sudden, unexplained weight loss can be a red flag for various types of cancer, including colon cancer. If you’re losing weight without trying or changing your diet and exercise habits, it could be due to the body’s reaction to a tumour. Cancer cells use up a lot of energy, which can lead to unintentional weight loss.
Persistent Abdominal Discomfort
People with colon cancer often experience frequent discomfort or pain in the abdomen. This may include cramps, bloating, or gas that doesn’t go away. These symptoms may be easy to dismiss as common digestive issues, but if they’re long-lasting and severe, it’s essential to get checked out.
Fatigue and Weakness
Feeling constantly tired or weak without a clear reason could also be a sign of colon cancer. This symptom might result from internal blood loss that isn’t easily noticeable, leading to anaemia. When the body doesn’t have enough red blood cells, you’ll feel fatigued even after resting or sleeping.
A Feeling of Incomplete Bowel Movements
Another symptom of colon cancer is the sensation that your bowel doesn’t empty completely, even after using the restroom. This could make you feel like you constantly need to go or that you’re never fully relieved. This feeling, coupled with other symptoms like pain or blood in the stool, can be a strong indicator that something is wrong.
