As the second greatest cause of mortality in USA, cancer is an important problem for global public health. Significant reductions in mortality have been observed over the past ten years as a result of enhanced therapies, detection methods, and targeted treatment development. A variety of cancer treatments already exist which exploit various tactics and scientific concepts such as chemotherapy, radiation therapy, photodynamic therapy, hormone therapy, immunotherapy, stem cell therapy, and targeted therapy. Most of them have been consolidated over the last few years; nevertheless, other therapies for curing liver and lung cancer, for example, are still unreliable and mostly, too invasive.
