AI reveals 10 clues of early colon cancer
Jan 13, 2026
Description
In this video, I break down the 10 earliest warning signs of colorectal cancer, ranked from least to most common.
The 10 early signs are:
Nausea and vomiting (5-10% of cases)
Mucus in stool (10-15%)
Persistent abdominal bloating/distension (15-20%)
Unintentional weight loss (15-20%)
Pencil-thin stools (25-30%)
Abdominal pain/cramping (25-30%)
Fatigue (30-40%)
Tenesmus - feeling of incomplete bowel evacuation (30-40%)
Persistent change in bowel habits (50-60%)
Blood in stool (60-90%)
Remember that these symptoms can be caused by other conditions like hemorrhoids, IBS, or inflammatory bowel disease. Some early-stage colon cancer patients may have no symptoms at all, which is why screening is crucial. Current guidelines recommend colonoscopy screening starting at age 45 for average-risk individuals.
I also compare different AI models to see which provides the most accurate medical information on this topic.
