Re**al cancer occurs when it develops in the re**um, while it's called colon cancer if it develops elsewhere in the colon. It's one of the few cancers that can be prevented through screening. Colore**al cancers may sometimes cause no symptoms at all. However, if you have experienced one or more of the following symptoms for a long time, you should consult a doctor:
- Blood in the stool or re**al bleeding
- Unexplained weight loss
- Anaemia
- Fatigue
- Nausea
- Vomiting
- Abdominal pain, bloating or flatulence
- Changes in bowel habits (such as constipation or diarrhoea).
- A change in the shape of the stool (e.g. thin, pencil-like stool).
