Cancer is developed when abnormal cell function and division occurs in the body, and can be life-threatening if diagnosis and treatment is not administered in the early stages of the disease. Commonly used treatments for cancer, including chemotherapy, radiation therapy and other drug treatments, cause treatment-related side-effects during treatment, as well as persisting negative side-effects in long-term survivors. These side-effects include, but are not limited to: pain, fatigue, negative changes in body composition, decreased bone health and impaired immune function.
