AIIMS, Harvard-trained gastroenterologist shares 8 early signs of colon cancer you should know

Colon cancer is a significant health concern that often progresses silently, making early detection critical for effective treatment. In a recent Instagram video, Dr. Saurabh Sethi, a gastroenterologist and liver specialist trained at AIIMS, Harvard, and Stanford, highlighted eight early warning signs of colon cancer that many people tend to overlook. These symptoms, which include blood in stool, persistent bowel changes, abdominal pain, and unexplained weight loss, are often mistaken for minor digestive issues like haemorrhoids or temporary gut disturbances. By raising awareness of these subtle yet crucial signs, Dr. Sethi emphasises the need for timely medical consultation and screening, as early detection can dramatically improve survival rates and prevent the progression of this potentially life-threatening disease.


Colon cancer early signs: 8 symptoms you should never ignore





Dr. Sethi explained that colon cancer can progress quietly, but recognising the following signs can prompt early medical consultation and improve survival outcomes:


Blood in stool

Noticing bright red or dark, tarry stools may indicate internal bleeding in the colon. While minor bleeding is often associated with haemorrhoids, persistent blood in stool should never be ignored.

Persistent bowel changes

Chronic constipation, diarrhoea, or a sudden narrowing of stools lasting more than a few days can be early warning signs. Any noticeable change in bowel habits should be medically evaluated.

Abdominal pain and cramping

Frequent bloating, cramps, or unexplained abdominal discomfort may signal issues in the colon. Dr. Sethi stressed that new or persistent abdominal pain warrants timely investigation.

Unexplained weight loss

Unexpected weight loss without dietary changes or increased activity may indicate that the digestive system is not absorbing nutrients properly, which can be a sign of colon cancer.

Ongoing fatigue

Chronic tiredness, weakness, or dizziness may result from slow blood loss in the colon, leading to anaemia. Dr. Sethi noted that fatigue should not be dismissed, especially when it persists over time.

Iron-deficiency anaemia

Low iron levels detected in lab tests, particularly in men or post-menopausal women, can be an early hidden indicator of colon cancer.

Feeling of incomplete bowel emptying

A sensation of not fully emptying the bowels after a movement may indicate obstruction or tumor growth. This subtle symptom often goes unnoticed but is important to recognize.

Family history of colon cancer

Individuals with close relatives affected by colon cancer have a higher risk. Dr. Sethi emphasised that screening should not be delayed if symptoms appear, particularly for those with a family history.

Importance of early detection: Early signs and screening for better outcomes

In his Instagram video, Dr. Sethi stressed that most colon cancers start silently and remain symptom-free in the initial stages. Detecting the disease early significantly improves the chances of successful treatment. Colonoscopy is the gold standard for early diagnosis and can identify precancerous lesions, making timely screening a life-saving step.
