Cancer cells

Learning about the body's capabilities at a cellular level is absolutely fascinating. Each cells is like a city with all the molecules performing specific duties doing extremely precise things like copying thousands of genes in our DNA. Studying this gives me so much respect for what our cells do. But then I read about cancer cells. They reak havoc in doing nothing but destroy the beautiful, amazing progress other cells have done in the process of living and growing. We start as one cell and our amazing cells differentiate and turn us into who we are. Then cancer comes in with complete disregard. Such a sad thing. I don't like those kinds of cells.
