Doctors say Sabrina Sabrok is risking her health if she has her 14th breast enhancement operation.

Sabrok, who works on Mexican TV, is already a size 42 triple G but wants to go on to be a 42 triple X, reports Las Ultimas Noticias.

A spokesman for the Plastic Surgeons’ Association of Argentina warned the weight would be too much for her body.

He said: "She is risking her health because there needs to be balance on the body and she will lose that if the breasts go too big.
