Oncology, the medical field dedicated to cancer study and treatment, involves oncologists who specialize in understanding cancer types, causes, and development. They collaborate with a multidisciplinary team to create personalized treatment plans, utilizing surgery, chemotherapy, radiation, and immunotherapy. Oncologists monitor patient responses, manage side effects, and adapt strategies for optimal outcomes. They also focus on cancer prevention through screenings, genetic counseling, and lifestyle advice. In advanced cases, oncologists provide palliative care to enhance the quality of life. Their involvement in research and clinical trials drives advancements in cancer therapy.
