What is Immunotherapy

Immunotherapy, also called biotherapy or biology therapy, is a treatment that uses the immune system to treat an illness. Immune systems can be developed, directed, or restored with various forms of immunotherapy in Kolkata. Several types of immunotherapy may be used for the treatment of cancer, such as biologics and vaccines.


Biologics is a medicine based on natural proteins. These drugs include:

Monoclonal Antibodies

This kind of medicine gets some protein on the surface of other cells and locks it in (as a key to the bag). This causes the immune system to attack and destroy those cells.
