Immune System and its Ability to Fight Cancer


A healthy immune system is required for cancer treatment as the immune system is partly responsible not only for preventing cancer but for treating cancer. The immune system can destroy abnormal cells in the body, killing the cell before it becomes a cancer cell.

One article (1) discussed the immune system and its ability to fight cancer. It noted that cancer cells might cause nearby cells to release agents that prevent the immune system from doing its job, express antigens on their cell surfaces that cause the immune system to malfunction, and reduce the expression of cancer antigens on the cell surface so the immune system can’t find them. Cancer immunotherapy involves the study of the ways that people can use the immune system to kill the cancer cells.

There is research ongoing that studies ways to increase the effectiveness of the immune system in fighting cancer, to increase the use of immunotherapy in fighting off cancer, and to understand why some people benefit from immune system therapy while others don’t have the same benefit.
