Unexpected Signs of Colorectal Cancer: Paying Attention to Thin Stools

Colorectal cancer is one of the most common diseases in France, affecting more than 47,000 people each year. The diversity of symptoms can make its diagnosis challenging, but certain signs should immediately raise concern. Among them, a particularly unexpected and worrying symptom: the appearance of thin stools.

Dr. Jeffrey Dueker, a gastroenterologist at the University of Pittsburgh, emphasizes that this symptom becomes particularly concerning when it persists.
