Medical Oncology includes Chemotherapy treatment, Immunotherapy Treatment, and Targeted therapy
Chemotherapy is the use of medicines to kill or reduce the spread of cancer cells. Chemotherapy is given as cycles and may be given once a day, once a week or even once a month. This depends on the type of cancer and the best regimen (course) as determined by research. Chemotherapy, unlike radiation (which treats only the part of the body exposed to the radiation), treats the entire body. As a result, any cells that may have escaped from where the cancer originated are treated.
Immunotherapy is a type of drug treatment that uses/stimulates your own immune system to fight cancer. It helps your immune system recognise and work against the disease.
Targeted Therapy is a type of drug treatment that targets specific mutations or proteins within the cancer cell. They do many things to the cancer cell including turning off signals telling the cancer cell to grow or divide.
