Cancer treatments are constantly evolving; one of the more recent shifts in treatment revolves around enhancing the natural immune response. Our immune system is excellent at destroying and removing damaged, faulty, or old cells, but in the case of cancer, it tends to need a little help. Psychotherapies are designed to stimulate a patient's immune system to fight the cancer within. Although the latest psychotherapies can be effective, they only work for the minority of patients who have solid tumors.
