Immunotherapy or biological therapy is an individualized treatment approach in which the body’s healthy immune cells are stimulated to attack the cancerous cells. Rather than taking drugs to fight against the cancer cells, immunotherapy provokes the body’s defence mechanism to destroy cancer cells. 

Some specialized immune cells are synthesized in the laboratory and injected into the patient’s body to fight against cancer. These include:

• Monoclonal antibodies therapy.
• Dendritic cells therapy.
• T-cells therapy.
• Oncolytic virus therapy.
• Cytokine therapy.
• Cancer vaccine.

Depending on the type and stage of your cancer, the oncologist may use one or a combination of the above immune cells to fight against the cancer cells.
