factors? - ----Answers---1. Divide w/o binding of growth
factor to receptors

___________ the cessation of growth after cells reach a certain
density, is often lost in cancer cells - ----Answers---Cell

In cancer cells, _____ _______ ________ ________are lost, meaning
cells do not stick together. This, in turn, permits the surface
cells of the tumor to shed into the surrounding body fluids or
secretions. - ----Answers---Cell cohesiveness and adhesion

keep high levels of _________, an enzyme that prevents
telomere shortening - ----Answers---Telomerase
Cancer cells contain several cell surface molecules or
antigens that are immunologically different from its normal
tissue counterpart. This refers to: - ----Answers---Antigen
