Are you aware of the signs of colorectal cancer?

If you observe any changes to your bowel habits or have any concerns about colorectal cancer, it’s important to seek out prompt medical advice. In this informative guide, highly respected consultant general surgeon Mr Greg Wynn shares his expert insight on the most common signs and symptoms of colorectal cancer.

What are the early warning signs of colorectal cancer?

Some early warning signs of colorectal cancer can include a subtle but persistent change in bowel habits that is recognisably different from your normal pattern. Although looser motions are more commonly associated with bowel cancer, constipation can also be a symptom.

Rectal bleeding should always be taken seriously and advice sought if this is ongoing. Abdominal pain, unexplained weight loss and fatigue can be associated with a wide variety of serious illnesses including the later stages of bowel cancer.

Can changes in bowel habits be a symptom of colorectal cancer?

Yes, changes in bowel habits, such as constipation or diarrhoea, can be a symptom of colorectal cancer. Your doctor may want to perform additional stool tests before deciding on the next best steps.

Can abdominal pain or discomfort be a symptom of colorectal cancer?

Yes, abdominal pain or discomfort can be a symptom of colorectal cancer, but there are many different causes of abdominal pain and your doctor will have to assess the likely underlying reasons why you are experiencing these symptoms.

Can rectal bleeding be a symptom of colorectal cancer?

Yes, rectal bleeding can be a symptom of colorectal cancer. It could be in the form of blood mixed with the stool or on toilet paper. New stool studies called faecal immunochemical tests will give additional information about the likely underlying cause of any bleeding.

Can unexplained weight loss be a symptom of colorectal cancer?

Unexplained weight loss can be a symptom of any cancer or other serious systematic illness. Symptoms associated with more advanced cancer such as anaemia, fatigue, weakness, loss of appetite and poor digestion should always trigger patients to seek the advice of a specialist.

Please note that the above list of symptoms is not exhaustive and not all patients with colorectal cancer will experience these symptoms. It's important to take part in the national bowel cancer screening programme if you are eligible and consult a medical professional if you have any concerns.
