What is Cancer?
Cancer comes in a variety of forms. Basically, cancer occurs when cells in the body begin to grow chaotically. Normally, cells grow, divide, and produce more cells to keep the body healthy and functioning properly. Sometimes, however, the process goes astray; cells keep dividing when new cells are not needed. Some types of cells are more prone to abnormal growth than others. The mass of extra cells forms a growth or tumor, which can be benign or malignant.
