What is a key function of cytokines in cancer treatment?

Cytokines play a crucial role in enhancing the immune response against cancer cells. They are signaling molecules that facilitate communication between cells, particularly within the immune system. In cancer treatment, some cytokines are used to boost the body’s ability to recognize and destroy cancer cells. For instance, cytokines like interleukins and interferons can stimulate various immune cells, including T-cells and natural killer cells, making them more effective at attacking tumors.

The enhancement of the immune response is significant because many cancers manage to evade detection by the immune system. By promoting the activity and proliferation of immune cells, cytokines help to improve the body’s natural defense mechanisms against the malignancy.

In contrast, other options do not align with the primary purpose of cytokines in cancer therapy. While cytokines can have various effects on the body, their primary function in the context of cancer treatment is centered around modulating the immune response rather than triggering cell division in tumors, altering metabolic processes, or directly reducing blood supply to tumors.
