Cancer is a general term that refers to a collection of related diseases. Cancer is an uncontrolled growth of abnormal cells in the body. Cancer develops when the body’s naturally controlled mechanism stops working. Old cells stop dying and instead grow uncontrollably, forming new and abnormal cells. In all types of cancer, some of the body’s cells start dividing without stopping and spread into surrounding tissues.
Cancer can start from almost any part of the human body, which is made up of trillions of cells. These abnormal cells have the ability to infiltrate and destroy normal body tissue. The disease also has the ability to spread in your whole body by means of lymph systems and blood. Cancer cannot be specified as one disease rather it is a group of many diseases.
