Cancer describes a collection of diseases which arise withing the cells. Normally, cells will divide, grow and die in an arranged and orderly fashion. Sometimes, however, cells will continue to divide even though the body requires no new growth. These cells will form growths within the body known as tumors, which can be classified as benign or malignant.
