  INFO/WWW-LINKS: 
     Colorectal 
    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 
    descending, 
    the transverse and coecum with ascending colon. Colorectal 
    carcinomas spread local, lymphatic and haematogenous - especially - to 
    the liver and the lung.
