The big difference is growth. Normal cells stop growing when there are enough in one spot.
For example: When you get a cut, cells go to heal the wound, and the cells grow. But when the work is done, the cells stop growing.
But, cancer/tumor cells (not at a wound) grow and grow even when touching the first layers of muscle and skin. This would be what creates the lump. So, these bad cells are very overgrown and practically swollen cells.
b tumor cells have a cell wall instead of a membrane
tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
cell division is not regulated in tumor cells
cell division is not regulated in tumor cells.
D) cell division is not regulated to tumor cells
d. mitosis is not regulated in tumor cells
Cancer cells are cancer because they have unregulated/ uncontrolled growth, and this happens when we have unregulated mitosis (which is cell growth/division)
Cancer cells have more genetic changes compared to normal cells, it may be a result in cancer, but not all changes cause cancer.
