What is the term used to describe the study of tumors?

The term that describes the study of tumors is oncology. Oncology encompasses the research, diagnosis, treatment, and overall management of cancer, including the biological and clinical aspects of tumors. This field focuses not only on the tumors themselves but also on the associated physiological responses, innovations in treatment, and preventive measures against cancer.

While pathology is related to the study of disease and can include the microscopic examination of tumor specimens, it is a broader term that covers all diseases, not just cancer. Radiology involves imaging techniques to visualize the body's structures and identify tumors but does not specifically study them. Cytology refers to the examination of cells, often used to detect cancer at a cellular level, but again is more specific than the broader field of oncology. Thus, oncology is the most comprehensive and accurate term for the study of tumors.
