Preventive Medicine and Oncology

The word Oncology is derived from Greek ónkos means tumor and logos mean study. Oncology is the branch of medicine that deals with the diagnosis and treatment of cancer. It involves therapeutic oncology (use of chemotherapy, hormone therapy, and other drugs to treat cancer), radiation oncology (use of radiation therapy to treat cancer), and surgical oncology (use of surgery and other procedures to treat cancer). The person who treats cancer diseases is known as anoncologist. In simple words, we can define that the study of cancer is oncology. There are different types of cancer like Breast cancer, Prostate cancer, Basal cell cancer, Lung cancer, Leukemia, Lymphoma and Colon cancer. Cancer is a form of disease where the cancer-causing cell will invade (cell start to grow out of control) and spread to other body parts.
