Oh dear, Mayra Lissette Contreras has died after having silicone injections in her butt. Don’t ask me, last thing I need is a bigger ass! Anywho, it seems Ms Contreras died from respiratory problems following the procedure. The two sisters Alejandra Viveros and Guadalupe Viveros, who performed the op, are on the run. It’s alleged they don’t even have a friggin medical license. Brilliant! Some California doctors are horrified by the practice, considering injecting silicone directly into the body can have serious medical repercussions eg DEATH. If the surgeon accidentally hits a vein, the silicone can enter into the bloodstream and go straight to the lungs.
