Bowel cancer, also known as colorectal cancer, can have a range of symptoms. However, many people with bowel cancer do not have symptoms at first. The symptoms of bowel cancer can be subtle and don’t necessarily make you feel ill. Here are some of the signs and symptoms of bowel cancer:

• A change in bowel habits, such as more frequent diarrhea or constipation, or a change in the appearance or consistency of bowel movements such as thin bowel stools.
• Rectal bleeding or blood in the stool, which might make it look dark brown or black.
• Ongoing discomfort in the belly area, such as cramps, gas, or pain.
• A feeling that the bowel doesnt empty all the way during a bowel movement.
• Weakness or tiredness.
• Losing weight without trying.

It is important to note that these symptoms can also be caused by other conditions, such as hemorrhoids or irritable bowel syndrome. However, if you experience any of these symptoms, especially if they persist or worsen over time, it is important to see a doctor for further evaluation and testing[[6]](https://www.cancerresearchuk.org/about-cancer/bowel-canc...
