Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized structure that facilitates their gatekeeping function.
The cell divides and grows in the organ of origin, causing a localized tumor. Cancer cells then spread to adjacent tissues or regional lymph node drainage areas, and then advance to distant organs or structures, creating metastatic tumors.
