A medical oncologist is a doctor who specializes in diagnosing and treating cancer. They use various methods, including chemotherapy, targeted therapy, and immunotherapy, to help manage the disease. Medical oncologists work closely with patients to create personalized treatment plans and monitor their progress throughout the treatment process. In addition to treating cancer, medical oncologists also provide support and guidance to patients and their families. They often collaborate with other healthcare professionals, such as radiation oncologists and surgeons, to ensure comprehensive care. Their goal is to improve the quality of life for patients while fighting the disease.
