Symptoms of colon cancer: The symptoms of this type of cancer may not be seen initially, and they will mostly depend on the size of the cancer and the affected area in the large intestine, warned gastroenterologist Dr Saurabh Sethi (Image: Pexels)

Colon cancer is the second leading cause of cancer-related deaths for both men and women around the world. While cases have been on the decline in Western countries due to early screening, the problem is still a concern among younger adults. Hence, early detection is necessary for improving survival rates.

Harvard-trained gastroenterologist Dr Saurabh Sethi, in his new Instagram post, explained some of the warning signs that people shouldn’t ignore as less serious symptoms of colon cancer.

While the symptoms may not be seen initially, they will mostly depend on the size of the cancer and the affected area in the large intestine. Symptoms can include:

• Blood in stool: Bright red or dark, tarry stools can signal bleeding in the colon. Don't assume it's just haemorrhoids.

• Persistent bowel changes:Constipation, diarrhoea, or narrowing of stools lasting more than a few days. Treat it as a red flag.

• Abdominal pain or cramping:Frequent bloating, cramps or abdominal pain that's new or unexplained deserves a check-up.

• Unexplained weight loss: Losing weight without dieting or lifestyle changes could mean your gut is not absorbing nutrients properly.

• Chronic fatigue: Chronic tiredness, weakness or dizziness may result from slow blood loss and anaemia.

• Unexplained iron-deficiency anaemia: If labs show low iron, especially in men or post-menopausal women, it can be an early hidden sign.

• Feeling of incomplete emptying: If it feels like you 'can't finish' after a bowel movement, it may point to blockage or tumour growth.

• Family history: Having close relatives with colon cancer increases your risk; don't delay screening if symptoms appear.

Diet plays an important role in reducing the chances of colon cancer.

• Eating a wholesome meal that includes fruits, vegetables, and whole grains is always helpful.
• A variety of fruits and vegetables helps increase the nutrient range.
• Refrain from drinking and smoking.
• Sneak in 30 minutes of movement every day.
• Consult your doctor before starting any heavy-duty regimen.
• Try to maintain a healthy weight for overall well-being.
