Oncology is a medical specialty dedicated to the study and treatment of cancer, focusing on its prevention, diagnosis, and management. It involves identifying cancer through diagnostic tests, determining the stage and type of the disease, and developing individualized treatment plans. Oncology care may include chemotherapy, radiation therapy, surgery, immunotherapy, or targeted therapies, often delivered through a multidisciplinary team. In addition to treating the disease, oncology also emphasizes symptom management, patient support, follow-up care, and improving quality of life for individuals affected by cancer.
