Medical oncology is a branch of medicine that focuses on the diagnosis, treatment, and management of cancer. Oncologists, the doctors specializing in this field, use various methods to treat cancer, including chemotherapy, immunotherapy, and targeted therapies. They work closely with patients to develop personalized treatment plans based on the type and stage of cancer. In addition to treating cancer, medical oncologists also provide supportive care to help manage symptoms and side effects of treatment. They often collaborate with other healthcare professionals, such as radiation oncologists and surgical oncologists, to ensure comprehensive care for patients throughout their cancer journey.
