Invertebrate Oncology: Diseases, Diagnostics, and Treatment

Neoplasia is a documented occurrence across invertebrate taxa, but challenges remain with regard to tumor diagnosis and treatment. Literature reports of neoplasia are frequent in mollusks and insects, infrequent in Cnidaria and crustaceans, and are yet to be documented in Porifera and echinoderms. A significant contribution could be made by veterinary practitioners documenting and treating neoplasms in invertebrates. Traditional methods of veterinary diagnosis are encouraged, but the anatomy and tissue biology of each invertebrate species need to be considered. Most neoplasms described in the invertebrate literature have been considered benign, making external lesions potentially amenable to surgical resection.
