What happens to a cell when it becomes cancerous ? A. the cell no longer responds to signals that regulate the cell cycle
B. the cell grows much larger and never stops growing
C. the cell dies

Explanation:

When cancer starts to grow within a cell, this cell’s function is altered and it begins to multiply out of control. Simply put, cancer cells are nothing but cells gone wrong - they no longer respond to the signals that control cellular growth and death. Subsequently, they divide more rapidly than their progenitors and become less dependent on signals from other cells.
