The approach is followed both from a macroscopic and a microscopic point of view. In the first case, one considers the tumour as a growing mass of cells, focusing on its external shape. In the second case, one descends to the microscopic level, studying molecular signalling pathways that are crucial to determine if a cell is cancerous or not. In each of these approaches we work with appropriate variants of membrane systems.}, keywords = {membrane system, modeling, tumour}, issn = {1002-0071}, url = {http://pub.nsfc.gov.cn/pinsen/ch/reader/view_abstract.aspx?file_no=449\&flag=1}, author = {Miguel A.
