Cancer is a complex disease that result from the basic process of uncontrolled growth. Cell proliferation results in a mass that invades neighbouring tissues and may metastasize to more distant sites. In order for a normal cell to transform into a cancer cell, genes which regulate cell growth and differentiation must be altered. When normal regulation is altered, uncontrolled growth is initiated and a malignant tumor develop. Cancer is caused by certain genetic changes that occurs at many levels, from gain or loss of entire chromosomes to a mutation affecting a single DNA nucleotide.
