Genes and Cancer
Advances in science have improved our knowledge of the inner workings of cells, the basic building blocks of the body. All living things are made of cells. Complex animals such as humans have trillions of cells. Cells work together to form organs, such as the heart, liver, and skin. Human bodies have several organ systems.
Cancer begins when genes in a cell become abnormal and the cell starts to grow and divide out of control.
