Medical oncologists are doctors who specialize in diagnosing and treating cancer. They use various methods, including chemotherapy, targeted therapy, and immunotherapy, to help manage the disease. These specialists work closely with patients to develop personalized treatment plans based on the type and stage of cancer. In addition to providing treatment, medical oncologists also monitor patients' progress and manage any side effects from therapies. They often collaborate with other healthcare professionals, such as radiation oncologists and surgeons, to ensure comprehensive care for individuals battling cancer.
