The body is made up of many types of cells, and a squamous cell is one. Squamous cells line organs, and are found throughout the body. Common locations of squamous cells include the skin, bladder, cervix, colon, throat, lung, and kidneys.
Normal cells grow, divide, and die in an orderly manner.
They grow and divide to produce more cells only when the body needs them. Sometimes, however, cells keep dividing when new cells are not needed. In cancer, these cells are abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Also, cancer cells can break away from the original tumor and enter the bloodstream to form new tumors in other organs.
