What branch of medicine deals with tumors or abnormal growths like cancer?

Oncology is the branch of medicine dedicated to the study, diagnosis, treatment, and management of tumors and cancers. Specialists in this field, known as oncologists, are focused on understanding the biology of tumors, conducting cancer therapies such as chemotherapy, radiation, and immunotherapy, and overseeing the overall care of patients with cancer. The term “oncology” derives from the Greek word “onkos,” meaning mass or tumor, which appropriately reflects the area of specialization.

In contrast, ophthalmology pertains to the medical and surgical care of the eyes and visual system, and odontology relates to the study and treatment of teeth and oral health. Oliguria is a medical condition characterized by lower than normal urine output, which is unrelated to cancer or tumor treatment. Understanding the distinct focus of oncology is pivotal for those pursuing careers in health sciences, as it plays a crucial role in addressing one of the most significant health challenges faced worldwide.
