In a Normal Cell Signal, a Growth Factor Binds to a Receptor

In a normal cell signal, a growth factor binds to a receptor in the cell membrane, the signal gets relayed molecule to molecule until it gets its message to the transcription factor which regulates gene activity and so regulates the genes controlling cell division. What happens in cancer cells?

A) The cells bypass this normal regulatory pathway and the cells divide out of control.
B) The cells receive too many signals via this pathway and divide out of control.
C) The cells receive signals that trigger mutation and so they divide out of control.
D) The cells bypass the normal regulatory pathway and stop dividing.
E) The cells attack the regulatory pathway, halting normal cell division.
