Immunology, Volume 1: Immunotoxicology, Immunopathology, and Immunotherapy discusses the investment of time, effort and finance that go into making progress in preventing and/or curing serious diseases by using standard treatments (chemotherapy, radiotherapy, surgery, and hormone therapy). The use of these treatments is accompanied by unavoidable, devastating side effects. At the cost of being repetitious, it has to be emphasized that an improved understanding of the immune system, avoidance of unhealthy habits (e.g., smoking, intake of alcohol, perpetual stress, and lack of exercise) and early detection (using biomarkers) are the only three friends we have to at least delay the onset of serious diseases.
