Cancers arising in different parts of the colon can cause different symptoms, and can ''metastasize", or spread, differently. Of special importance, cancers of the rectum have greater potential to spread to several parts of the body at once, while cancers from the rest of the colon tend to spread first to the nearby lymph nodes, and then to the liver.
