Cancer
Cancer is a class of diseases in which a group of cells display uncontrolled growth, invasion, and sometimes metastasis. The branch of medicine concerned with the study, diagnosis, treatment, and prevention of cancer is oncology.Cancer Immunoediting is a process by which a person is protected from cancer growth and the development of tumour immunogenicity by their immune system. It has three main phases: elimination, equilibrium and escape. Although numerous studies using several different tumor models have revealed a definitive role for certain immune components in protecting the host from cancer, a seeming controversy persists about whether the immune system protects against or promotes cancer. Perhaps this conflict arises from the inaccurate generalization of immune function. Clearly, not all immune components play fixed roles in all models of cancer. Hence the relationship between cancer immunoediting and cancer promoting inflammation cannot be simply defined based on single tumor models, and in fact might change even within related systems. The tumor microenvironment represents complexes system in which individual immune cells make potentially interconnected decisions to attack tumor cells, ignore their presence, or enhance their development and/or survival. These decision-making processes, and the potential to beneficially influence them in the clinical setting, represent significant areas of research that beckon future studies.
