Colorectal cancer symptoms and stool changes
Changes in stool shape and consistency, particularly stools that are unusually thin like a pencil, can be indicators of colorectal cancer. While such changes can be caused by benign factors like diet, hydration, constipation, diarrhea, or irritable bowel syndrome, they may also signal an intestinal obstruction caused by a tumor in the colon or rectum reducing the passage space.
Medical experts from Johns Hopkins Medicine note that unusually narrow stools are among the possible manifestations of colorectal cancer. However, stool shape alone is not a definitive indicator, as early-stage cancer may present without obvious symptoms.
Other symptoms that warrant medical consultation include persistent changes in bowel habits, blood in the stool (red, black, or dark red), recurring abdominal pain, unexplained weight loss, unusual fatigue, anemia, or a palpable nodule in the abdomen. The Romanian Ministry of Health includes changes in transit, blood in the stool, and repeated abdominal pain among signs requiring investigation. The NHS recommends seeking urgent medical help for black or dark red stools and bloody diarrhea.
