The gastroenterologist stressed that cancer of the colon<\/a> or rectum usually starts silently. Therefore, most people tend to overlook the symptoms. Here are some signs that should alert you and push you or your loved ones to visit an expert.<\/p>\n

8 colon cancer warning signs you should never ignore<\/p>\n

In the post, the gastroenterologist pointed out that subtle signs like changes in your bowel movement, unexplained weight loss<\/a>, pain in the abdomen, fatigue, or even the feeling of incomplete bowel movement can all point towards colon cancer. Therefore, at the first sign, one should visit their physician. Here are the 8 signs you shouldn’t ignore:<\/p>\n

1. Blood in stool<\/p>\n

Bright red or dark, tarry stool can signal bleeding in the colon. Dr Sethi stressed that you shouldn’t assume it’s just haemorrhoids.<\/p>\n

2. Persistent bowel changes<\/p>\n

\u201cConstipation, diarrhoea, or narrowing of stools lasting more than a few days is a red flag,\u201d the gastroenterologist warned.<\/p>\n

3. Abdominal pain or cramping<\/p>\n

Frequent bloating, cramps, or abdominal pain that’s new or unexplained deserves a check-up.<\/p>\n

4. Unexplained weight loss<\/p>\n

Dr Sethi said, \u201cLosing weight without dieting or lifestyle changes could mean your gut isn’t absorbing nutrients properly.\u201d<\/p>\n

5. Ongoing fatigue<\/p>\n

Chronic tiredness, weakness, or dizziness may result from slow blood loss and anaemia, and could be a sign of colon cancer.<\/p>\n

6. Unexplained iron-deficiency anaemia<\/p>\n

\u201cIf labs show low iron, especially in men or post-menopausal women, it can be an early hidden sign of colon cancer,\u201d Dr Sethi highlighted.<\/p>\n

7. Feeling of incomplete emptying<\/p>\n

\u201cIf it feels like you \u2018can’t finish\u2019 after a bowel movement, it may point to blockage or tumour growth,\u201d the gastroenterologist said.<\/p>\n

8. Family history<\/p>\n

Lastly, if you have close relatives with colon cancer, it increases your risk. Therefore, don’t delay screening if symptoms appear.<\/p>\n

All you need to know about colon cancer<\/p>\n

According to the gastroenterologist, most colon cancers start silently, which is why if the signs appear, you should consult your doctor. If caught early, there’s a 5-year survival rate of 90 percent. \u201cDon’t wait if you notice symptoms. Get screened – colonoscopy saves lives,\u201d the expert stressed.<\/p>\n
