C: Right present earlier then left sided cancers
Answer: C: Right present earlier then left sided cancers 
Explanation: Tumours of the left side of the colon usually present with a change in bowel habit or rectal bleeding, while proximal lesions typically present later, with iron deficiency anaemia or a mass.Iron deficiency anaemia in any man or non-menstruating woman should lead to a search for a source of bleeding from the GI tract.Emergency presentation occurs in 20% of cases and is associated with a considerably worse prognosis,Left side cancers are more common, but in recent decades the incidence of right is increasing.Ref: Bailey and love, 27e, page: 1262
