How Does A Cell Become Cancerous?

Cells growth and division is controlled by genes. One part of the gene stimulates and growth and another part of the gene restrains it. Those two pieces need to work in perfect harmony in order to have a normal rate of cell division. When cells divide much faster than usual they form a tumor. All cancers develop from a primary tumor.If the tumor sheds cells in the blood or lymph they will go on to form a secondary tumor elsewhere in the body.
