Exploring the contrasts among chemotherapy, immunotherapy, and targeted therapy is key to fully grasping the workings of cancer drugs
Drugs were not considered to be a "cure" for cancer until the 1960s; the cornerstones of cancer treatment were surgery and radiation. In the late 1930s, pharmacological therapies for prostate cancer in males produced, at best, a short-lived, incomplete remission. Hormone therapy was an exception. After the National Cancer Act of 1937 established the National Cancer Institute (NCI) and provided funding for cancer research, medical professionals and researchers started to focus more on employing chemical agents and pharmaceuticals to treat cancer. When chemotherapies were used to successfully treat children with leukaemia and adults with Hodgkin's lymphoma in the 1960s and early 1970s, these treatments represented the first major advances. More than 600 medications are currently approved in the US to treat cancer. The majority of them fight cancer in various ways and can be divided into three primary categories: chemotherapy, immunotherapy, and targeted therapy. Chemotherap...
