Oncology is the study of all types of tumorous cancers, which are defined as uncontrolled growths of certain cells of the human body. The main objective of oncology is to better understand the different possible causes of all types of cancer, as well as how they develop, in order to prevent or cure them more efficiently in the future. Oncologists decide on the best treatment methods to implement for a particular patient, taking into account personal patient characteristics, general condition, and the type of cancerous tumor involved, along with its progression, either localized or spreading to the lymph nodes or even to other organs, and prognosis. This specialty is hospital-based, and frequently involves many different disciplines, calling upon the expertise of specialists of the affected organ, radiologists, radiologic technologist, and so on.
