Targeted Therapy: What Is Replicative Immortality in Cancer?

NettetCancer cells develop the ability to invade surrounding tissue and spread and colonise distant sites by activating invasion and metastasis programs. Enabling replicative immortality. Cancer cells overcome physiological limits on the total number of cell divisions (Hayflick limit) to achieve limitless replicative potential.
