IT IS COMMON KNOWLEDGE THAT CANCER IS GENERALLY INHERITED, THIS PAPER WILL FURTHER EXPLORE THE CAUSES AND WHAT HAPPENS ON A CELLULAR LEVEL WHEN CANCER DEVELOPS IN THE HUMAN BODY.
                      ABNORMAL CELL GROWTH LEADING TO CANCER CANCER IS THE SECOND LEADING CAUSE OF DEATH IN THE UNITED STATES. HALF OF ALL MEN AND ONE-THIRD OF ALL WOMEN IN THE U.S. WILL DEVELOP CANCER DURING THEIR LIFETIMES. ALTHOUGH IT IS COMMON KNOWLEDGE THAT CANCER IS GENERALLY INHERITED, THIS PAPER WILL FURTHER EXPLORE THE CAUSES AND WHAT HAPPENS ON A CELLULAR LEVEL WHEN CANCER DEVELOPS IN THE HUMAN BODY.
BASICS OF SIGNAL TRANSDUCTION CELL COMMUNICATION, OR SIGNAL TRANSDUCTION, IS SIMPLY THE MEANS BY WHICH CELLS IN THE BODY RESPOND TO SIGNALS COMING FROM OUTSIDE THOSE CELLS. THE PURPOSE OF THIS CHEMICAL COMMUNICATION IS TO COORDINATE FUNCTIONS INSIDE THE CELL, BETWEEN CELLS OR BETWEEN ORGANS IN THE BODY, ALLOWING US THE MEANS TO RESPOND TO OUR EXTERNAL ENVIRONMENT.
NORMALLY, CELL DIVISION IS A VERY CAREFULLY REGULATED PROCESS THAT ENSURES THE BODY HAS NEITHER TOO FEW NOR TOO MANY OF A GIVEN CELL TYPE. SOME CELL TYPES IN THE BODY WEAR OUT QUICKLY AND NEED TO BE CONTINUOUSLY REPLACED AS THEY DIE, SUCH AS MOST BLOOD CELLS AND CELLS LINING THE DIGESTIVE TRACT. THE PRODUCTION OF THESE CELLS MUST BE PRECISELY REGULATED BASED ON THEIR RATE OF CELL DEATH SO THAT THE BODY HAS THE EXACT NUMBER OF CELLS IT NEEDS.
