Dr Joseph Salhab, a gastroenterologist from US-based Advent Health hospitals, took to Instagram on September 16 to share a post about colon cancer that 'may save yours or a loved one’s life'. He wrote in his caption, “Colon cancer is one of the most preventable cancers if caught early.”

Colon cancer is highly preventable if caught early

In his post, Dr Salhab said, “One thing I constantly hear from my followers is that they feel like their symptoms are brushed off, causing fear and anxiety- and they don’t know what to do. Use this guide to track your symptoms and bring it to your next doctor’s appointment. That way, you and your doctor can work together to decide whether the symptoms are serious and what steps to take.”

12. Bloating or distension that doesn’t improve

13. Early satiety (feeling full after a small amount)

14. Nausea or vomiting without another explanation
