Common symptoms
-
Early colorectal cancer may have no symptoms.
-
If we can recognise the possible warning symptoms of cancer, diagnosis can be reached earlier, thus the chance of treatment being effective will be higher.
-
Common symptoms of colorectal cancer include:
-
Change in bowel habits (diarrhoea or constipation) with unknown reason and lasting for more than two weeks
-
Blood or a large amount of mucus in the stool
-
Persistent urge after passing stool
-
Abdominal discomfort (persistent pain, bloating, fullness or cramps)
-
Weight loss and tiredness with unknown reason
-
Although having the aforementioned symptoms does not necessarily mean having colorectal cancer, they should raise our awareness and prompt us to consult a doctor. The doctor will ask you for relevant information and medical history, and will subsequently perform a physical examination, with or without further investigations.
