Through T-cell engineering, researchers at the California South University (CSU) Cancer Research Institute (CRI) have shown that tumor growth can be stopped in a variety of cancers and prevented from spreading to other tissues. Findings from this study are the result of decades of research by Professor Alireza Heidari, a member of the Cancer Biology Research Program at the California South University (CSU), who discovered a protein called AH that can inhibit the growth and spread of cancer cells in several different ways. They become in the tissues of the body. Keywords: Cancer; Cells; Tissues, Tumors; Prevention, Prognosis; Diagnosis; Imaging; Screening; Treatment; Management
