Diseases of the Large Intestine — Neoplastic diseases —

Neoplastic lesions of the large intestine are increasing in Japan in conjunction with the changes in the dietary life of the population. Exact diagnosis of the diseases of the large intestine are still being debated. However, recent advances in diagnostic imaging provide improved diagnosis of neoplastic lesions of the large intestine without undue stress on the patient. In this paper, recent diagnosis, treatment and surveillance of neoplastic lesions such as early cancer, advanced cancer, mucosa-associated lymphoid tisssue tumor (MALToma) and gastrointestinal submucosal tumor (GIST) are discussed.
