Lecture notes from Imperial College London, Medical Biosciences BSc, 2nd year, Cancer Biology (CBIO) module For a cancer to be initiated, certain changes must take place within the genes of a cell. These genes usually control the process of cells growing and reproducing only as required, in an orderly and controlled way (cell proliferation, differentiation, and survival). Studies of tumour viruses revealed that specific genes (called oncogenes) are capable of inducing oncogenic cell changes, ...
