Cancer is one of the leading causes of death in the Caribbean. There are many kinds of cancer: in fact cancer is the general name given to a group of more than 100 diseases which all develop as a result of abnormal cell-growth. The abnormal cells usually form into a tumour (a lump or mass) but there are some  cancers, like leukaemia, which do not form tumours, and it must be noted that not all tumours are cancerous.
