DOI: 10.1016/j.gtc.2007.12.002 Abstract Colon cancer is believed to arise from two types of precursor polyps via two distinct pathways: conventional adenomas by the conventional adenoma-to-carcinoma sequence and serrated adenomas according to the serrated adenoma-to-carcinoma theory.

Where does cecum cancer spread to?

Where does cecum cancer spread to? The lymph nodes and the abdominal wall are areas where cecum cancer, a right-sided colon cancer, may spread. In rare instances, it may also metastasize to the ovaries or bones. Cancers on the right side of the colon are less likely to spread to the lungs and liver than left-sided colon cancers. 17
