In brief: See below

Anus is about 3-4 cm long from skin to the rectum which is the last part of colon.
Colon is lined by columnar lining and cancer of this is very common and runs in families. Cancer arising in the anal skin which is squamous kind is more like skin cancer. Treatment is very different as is prognosis.
