Immunotherapy is a form of cancer treatment that helps your immune system to battle cancer. It is a type of biological therapy and this type of treatment uses constituents made from living organisms to treat cancer. It can be done in a couple of ways comprising stimulating your own immune system to work harder or smarter to attack cancer cells or by giving your immune system components, such as man-made immune system proteins.
In the last few decades, immunotherapy has become an important part of treating some types of cancer. Newer types of immune treatments are now being tested and undergoing research, and they will impact how cancer is treated in the future.
