MYTH: Breast Implants Burst Above a Certain Altitude
False. According to some rumors, breast implants can "explode" in any atmosphere with extremely high or low air pressure, and flying high in the sky (or scuba diving in the deep) qualify. Implants do change subtly (you may even notice them temporarily expand in size), but if the atmospheric pressure were that smothering, everyone would combust. We’d worry more about whether fellow passengers think they’re fake.

You should learn to use "find" or google a subject before posting.

If you did, you would find that this subject was done on mythbusters about 6 years ago.

THey indeed did test this yes...

They found out that the gal would die due to oxygene starvation long before the implants exploded....
