The Uruguayan governing body said in a letter: "The Uruguay Football Association has become aware of statements made by the vice-president of FIFA, Mr Jim Boyce. These expressions refer to the Uruguayan player Luis Suarez, calling his conduct an act of 'cheating' and that such a situation is a 'cancer' for football.
"We understand that this kind of comment coming from a person who holds the position of vice-president of FIFA, with specific reference to a football player and linking their actions to a disease that is a scourge on humanity, are at odds with the principles governing world football.
"Deliberately ignoring his position and role Mr Boyce has referred specifically to a football player, encouraging and provoking hostility towards them."
Meanwhile, Suarez has claimed that he needs to improve his conduct on the pitch.
