The main difference between cancer cells and normal tissue stem cells is that cancer cells are abnormal and present mutations.
Cancer results from a series of molecular events that fundamentallyalter the normal properties of cells. In cancer cells the normal controlsystems that prevent cell overgrowth and the invasion of other tissuesare disabled. These altered cells divide and grow in the presence ofsignals that normally inhibit cell growth; therefore, they no longerrequire special signals to induce cell growth and division.
