Medical Oncology is the treatment of cancer with medicines. There are several different ways in which the medicines work to help treat cancer. One would be to kill cancer cells directly. Traditionally, this has been referred to as chemotherapy. We can harness the body’s immune system to seek out and destroy cancerous cells. This is now referred to as immunotherapy. We can also identify particular mutations that drive the cancer cells growth and either reverse or slow those processes. These targeted therapies are often referred to as biologic therapy.
