bowel cancer stomach noises, also known as bowel sounds, are typically normal and occur as the intestines move food, liquids, and gas through the digestive tract. However, in the case of bowel cancer, changes in bowel sounds may become noticeable. These changes can be due to obstructions, blockages, or abnormal motility caused by tumors. Bowel cancer can also lead to other symptoms like abdominal pain, bloating, constipation, or diarrhea. If accompanied by unusual stomach noises, persistent changes in bowel habits, weight loss, or blood in stool, it's important to seek medical advice to rule out any serious underlying conditions.
