Dendritic cells (DC) are the most specialised cells of the immune system. They are also the most efficient as they can capture the most insignificant amount of antigens and break them into peptides to activate T cells. They are the only cells of the immune system that can initiate antigen-specific immune responses.
Dendritic cells have finger-like projections, that capture their targets like bacteria, viruses or cancer cells. At first, they internalize it, then break it down to peptides, and then project the peptides on their surface, for T cells to recognise them. When a naive T cell comes in close proximity to a Dendritic cell, there is stimulation of the T cell. The naive T cell gets converted to a committed T cell- i.e. committed to doing its job of killing the target enemy.
This is how the infections are fought, as well as how the cancer cells are killed by the immune system.
When the immune system is successfully used, the targets are destroyed with little or no collateral damage.

Former US President Jimmy Carter got cured of his cancer by Immunotherapy. In 2015, he had aggressive cancer (metastatic melanoma), that spread through his body and he wasn’t expected to survive. With immunotherapy, he had a miraculous recovery, with his liver and brain lesions gone. He is 97 and continues to be free of cancer.
