Identifying and attacking specific cancer cells in the body can be easily achieved through targeted therapy. This treatment method employs the use of drugs and other substances. Targeted therapy can be combined with different types of treatment or be administered alone. Some of the treatments it can be administered include surgery, standard chemotherapy, traditional treatment, or radiation therapy. As a patient, if your radiation oncologist has informed you that you would be undergoing targeted treatment, understanding what it entails and how it works would help you prepare for the treatment and ultimately help you improve your care.
