This book offers outstanding approaches to understanding the role of the tumor microenvironment (TME) in cancer development and metastasis. The TME, with its multifaced role, is fundamental in the control and exacerbation of almost all cancer types. The outcome of many solid tumors is dependent on the modulation of the TME. Local tumor immunity, which is crucial in the control of cancer promotion, is one of the leading compounds of the TME. This book presents new insights and provides detailed and updated descriptions of the role of the TME in the control and the development of almost all cancer types. This book is an authentic source of knowledge, useful for researchers, medical doctors, students, and all individuals interested in understanding the mechanisms of cancer control and development.
