Cancer is a class of diseases that is characterized by uncontrolled cell growth. They cause harm when altered cells divide uncontrollably to form lumps or masses of tissue called tumours. The only exception is in the case of leukaemia where cancer prohibits normal blood function by abnormal cell division in the blood stream.
In 2012, the World Health Organisation estimates that, worldwide, there were 14 million new cancer cases and 8.2 million cancer-related deaths. Also, the American Cancer Society stated that ‘‘Cancer is the second most common cause of death in the US and accounts for nearly 1 of every 4 deaths’’.
