The main difference between cancer cells and normal tissue stem cells is that cancer cells are abnormal and present mutations.
Cancer is the uncontrolled growth of abnormal cells in the body. Cancerous cells are also called malignant cells. Cancer grows out of cells in the body. Normal cells multiply when the body needs them, and die when they are damaged or the body doesn't need them.
