Explanation:
cancer cells continue to grow they fail to listen to the signal that tells them to stop
cancer cells do not stick to nearby cells like normal cells they lack stickiness caused by adhesion molecules, can break free ans float to other regions of the body
cancer cells are immortal normal cells have a lifespan cancer cells defy death on the end of the chromosomes is a structure known as telomere. everytime a cell divieds it becomes shorter to a point where the cell dies cancer cells figures out a way to restore their telomeres so they dont shorten as the cells divide and they become immortal

muscular-produce force and cause motion,
nervous-transmit nerve impulses that move information around the body.
