The main difference between cancer cells and normal tissue stem cells is that cancer cells are abnormal and present mutations.
Cancer cells are abnormal. They keep dividing even when new cells are not needed. Sometimes cells form a mass of tissue called a tumor. Tumors can be either benign or malignant. Benign tumors are not cancer. However, malignant tumors invade healthy tissue and result in cancer. They can also spread to other parts of the body.
