carcinomas are adenocarcinomas
which may often arise in pre-existing polyps. About 40% of these carcinomas
are located in the rectum, 20-30% in the sigmoid colon, and about 30% in the
the transverse and coecum with ascending colon. Colorectal
carcinomas spread local, lymphatic and haematogenous - especially - to
the liver and the lung.
