Answer

In addition to tumor cell alterations, the microenvironment may promote tumor growth by paracrine influences, including vascular endothelial growth factor (VEGF) production and aberrant E-cadherin expression. Finally, a growing body of research over the last decade indicates that epigenetic alterations may silence tumor suppressor genes and that they represent important events in tumor progression.
