For first time father of medicine (Socrates) to reveal cancer and explain new debate in this field, until now propose various ways for therapy cancer but a lot of these way do not reach the tumor site and produce side-effects.at this time open new gateways for cancer and another malady that one of them is drug delivery system (DDS). A drug is transported to the place of action, hence, its influence on vitaltissues and undesirable side effects can be minimized. Various nanostructures, including liposomes, polymers ,dendrimers ,micelles , carbon and metal nanoparticles have been tested as carriers in DDS ,But in this between polymers have different and important role.in this review we focus on polymer drug delivery system for cancer treatment by responsivity to temperature and pH.
