• Change in bowel habits (constipation or diarrhoea)

• Blood in the bowel movements

• Feeling weak, tired, or short of breath 

• Low iron level, commonly with anaemia (iron deficiency anaemia)

• Black or dark-coloured stools (meaning your stomach is bleeding)

All in all

Colorectal cancer can be fatal. Therefore it is important to get regular medical checkups, especially if the cancer is in the family history, so that the signs and symptoms of the cancer can be detected earlier (if there is any), and treatment will be given accordingly, thereby increasing the survival rate. Another important thing in order to reduce the risk of getting colorectal cancer is to maintain a healthy lifestyle.
