Immunotherapy is the treatment of cancer by activating the immune system. In this type of treatment, the objective is to make the cells of the immune system identify the tumor cells, recognizing them as foreign elements and destroying them.

Immunotherapy has been used in the treatment of melanoma, through the administration of interferon and/or interleukin-2, drugs capable of stimulating the immune system, in addition to having a direct antitumor effect.

In cases of early bladder cancer, intravesical instillation of live attenuated bacteria has been shown to be beneficial in reducing the risk of recurrence of lesions removed by endoscopic surgery, probably thanks to the activation of the patient’s immune response.
Other tumors that can be treated with immunotherapy include kidney cancer and some cases of skin cancer.
