Where do you come from? http://www.jazzmasters.pl/new/disertation-writing-help/ people write papers for money  We need better molecular techniques to figure out which of those abnormalities that we find on screenings are going to kill us and which ones will never do anything. Until then, one of the points of this is people need to get used to the possibility that doctors, if you do have an abnormality, may treat it aggressively, somewhere in the middle or they may say, "Let's just do nothing and watch and wait and see what happens."
