What does oncology study?

Oncology is the branch of medicine that studies, diagnoses, and treats cancer. It involves understanding how normal cells transform into cancerous ones, how tumors grow and spread, and how different treatments can stop or slow disease progression. Oncologists specialize in therapies such as surgery, chemotherapy, radiation, and immunotherapy. The field also focuses on cancer prevention, early detection through screening, and palliative care for patients in advanced stages. Oncology research continuously evolves to discover new drugs and personalized treatments. Early diagnosis and targeted therapy have significantly improved survival rates and quality of life for many patients.
