Cecal cancer grows where the small intestine meets the colon, on the right side of the belly. Because stool is still liquid there, early signs are easy to miss.

Dull right-side pain is the first clue. It feels like a persistent ache or cramp low in the belly and doesn’t go away with gas or stool.

Hidden bleeding is common. Stool looks normal, but blood tests show anemia, or the stool turns dark and tarry.

Low-grade fever or night sweats can appear as the tumor irritates the body.

Weight loss is sneaky. Clothes feel looser even though appetite stays the same.

Bowel habits shift. You may have loose stools or feel full quickly, but constipation is less common.

Late signs include a hard lump you can feel on the right side, weight loss, or yellow skin—an alarm the cancer has spread.
