Symptoms of bowel cancer can be difficult to recognise because they often resemble common digestive problems.
According to Newsner, a doctor is highlighting a particular warning sign that many people may overlook.
Feeling like you haven't finished using the toilet
If you frequently feel that you still need to pass stool, even after using the toilet, it could be a warning sign.
Dr Asiya Maula explains that this sensation can sometimes be caused by changes in the bowel or rectum.

Blood in your stool
Visible blood in your stool is a symptom that should be investigated. It can be a sign of bowel cancer, although there are several other possible causes.
Unusual tiredness
If you frequently feel extremely tired without an obvious explanation, it could be a sign of anaemia.
According to the World Cancer Research Fund, anaemia can sometimes be associated with bowel cancer.
Bloating
Frequent bloating can be a symptom of bowel cancer.

Although bloating is often caused by other digestive problems, it is important to pay attention if it persists.
Changes in bowel habits
If you suddenly start going to the toilet more or less frequently than usual, it may be worth getting checked.
Persistent changes in bowel movements, in particular, should be taken seriously.
Unexplained weight loss
Losing weight without changing your diet or deliberately trying to lose weight can be a symptom of bowel cancer.

Pain in the lower abdomen

According to the World Cancer Research Fund, it is among the symptoms people should watch out for.
Shortness of breath
If you become breathless more easily than usual, it could be caused by anaemia. In some cases, anaemia can develop as a result of bowel cancer.
Alternating between diarrhoea and constipation
Some people experience periods of diarrhoea followed by constipation.

These changes can be caused by common digestive problems, but they may also be signs of bowel cancer.
Rectal bleeding
Bleeding from the rectum is a symptom that should not be ignored.
If the bleeding is heavy or persistent, it is important to seek urgent medical attention.
A lump in the lower abdomen
A noticeable lump in the lower abdomen can be a possible sign of bowel cancer.

Black or dark red stool
According to the UK's National Health Service (NHS), people who notice black or dark red stool should contact a doctor promptly, as this could indicate bleeding, Newsner reports.
Bloody diarrhoea
Diarrhoea containing blood is a symptom that requires prompt medical assessment.
The NHS recommends seeking an urgent medical appointment if you experience this symptom.
Recurring symptoms
Even minor digestive problems may be worth investigating if they persist or keep returning.
Many of these symptoms can be caused by harmless conditions, but persistent changes in the body's normal functions should be assessed by a doctor.
