Defined as a scientific discipline in and of itself, oncology conducts an examination of cells. It is based on the investigation of numerous conditions from the formation of cancer cells to their relationship with inheritance. Basically, it is the branch that examines the tumors formed in the body. 

In addition to examinations in many areas such as breast, lung, colon, bladder, and skin, examinations for brain tumors are also included under the oncology branch. At first, the reasons for the formation of cancer cells or tumors are examined. Next, diagnosis and treatment stages are conducted. Also, it is revealed as a result of examinations whether the condition is hereditary. Following these stages, chemotherapy practices are initiated.
