Colon (colorectal) cancer begins when small growths called polyps form on the inner lining of the colon or rectum. Over time, changes in the DNA of these cells can cause the polyps to become cancerous.As abnormal cells multiply, they replace healthy cells and eventually form a mass known as a tumor. This process develops slowly, often taking up to ten years for a precancerous polyp to turn into cancer and begin showing symptoms.Colon cancer poses serious health risks because cancerous cells can invade healthy tissues. Over time, they may break away and spread to other parts of the body, making detection more difficult since the symptoms can resemble other conditions.What Is the First Sign of Colon Cancer You Shouldn’t Ignore?Colon cancer can be difficult to detect because it often develops without obvious symptoms. However, doctors emphasize that the number one warning sign is rectal bleeding or blood in your stool."Colon cancer can be hard to diagnose because it can develop asymptomatically,” said Dr. John Nathanson, a gastroenterologist at New York-Presbyterian Allen Hospital.Dr. Pratima Dibba adds that this symptom should not be misdiagnosed as hemorrhoids, infection, or constipation, since early signs of colon cancer can look similar. She urges patients to get checked promptly to rule out serious conditions.Research from the Cleveland Clinic also shows that blood in stool can originate anywhere in the gastrointestinal tract, including the colon.Detecting colon cancer early is critical, as survival rates can be as high as 90 percent when caught in its initial stages.What Are Other Symptoms Of Colon Cancer?Persistent changes in bowel habits (diarrhea, constipation, or narrowing of stool). Other signs include: Abdominal (belly) painBloated stomachConstipation or diarrheaFeeling like there’s still poop in your bowel even after you go to the bathroomFeeling tired or weakUnexplained weight lossPresent Day Scenario In IndiaColorectal cancer (CRC) is a major health concern worldwide. In India, it is the fourth most common cancer among both men and women. In 2022, there were 64,863 new cases and 38,367 deaths. Projections suggest that incidence will continue to rise by 2026, reflecting both lifestyle changes and improved detection.Compared to developed countries, survival rates in India remain lower, largely due to late-stage diagnosis and limited access to screening programs.The American Cancer Society notes that colorectal cancer is a cancer that starts in the colon or the rectum. Colorectal cancer impacts around 1.9 million people every year, noted the World Health Organization (WHO) as per its 2022 data.Some of the risk factors include risk factors involve being over the age 50, family history, certain genetic syndromes (like Lynch syndrome), inflammatory bowel diseases, and lifestyle factors (diet high in red meat, alcohol, smoking, inactivity). The most effective way to prevent colorectal cancer is through annual colonoscopies, screening and stool tests.
