The main difference between cancer cells and normal tissue stem cells is that cancer cells are abnormal and present mutations.
Cancer Cell Properties. Cancer cells have characteristics that differ from normal cells. 1  Cell Reproduction: Cancer cells acquire the ability to reproduce uncontrollably. 2  These cells may have gene mutations or chromosome mutations that affect the reproductive properties of the cells. Normal cells reproduce properly. 2  Except for sex cells, all cells of the body reproduce by mitosis. 3  Sex cells reproduce through a process called meiosis. 4  Cell Communication: Cells communicate with other cells through chemical signals. 5  These signals help normal cells to know when to reproduce and when to stop reproducing.
