Cancer

Cancer is defined as uncontrolled growth of abnormal cells in the body. These abnormal cells are called malignant cells. Cancer grows out from the normal cells which multiply when the body needs them and dies when the body does not need them. It appears that cancer cells grow when the cells in the body grow out of control or when the cells forget to die. Cancer has been known to develop after affecting any kind of organ or tissue for instance; the breasts, skin, lungs, mouth, prostrate, colon, bones among others.
