A cancer specialist doctor, also known as an oncologist, is a medical professional who specializes in the diagnosis, treatment, and management of various types of cancer. These highly trained doctors play a crucial role in the fight against cancer and are dedicated to improving the lives of patients affected by this disease. Cancer specialists undergo extensive education and training to gain expertise in oncology. After completing medical school, they pursue a residency program in internal medicine or paediatrics, followed by a fellowship in oncology. This comprehensive training equips them with the knowledge and skills necessary to handle the complexities of cancer care. One of the primary responsibilities of a cancer specialist doctor is to diagnose cancer in patients. They employ various diagnostic techniques, such as biopsies, imaging tests, and laboratory analyses, to determine the presence and extent of cancer. Through their expertise and experience, they can accurately identify the type of cancer and its stage, which is crucial in designing an effective treatment plan.
