A common urban legend suggests that breast implants might "explode" or "leak" due to changes in cabin pressure, but this is entirely false. Modern silicone and saline implants are highly resilient and are tested to withstand pressures far greater than those found in a pressurized aircraft cabin. The air pressure inside a plane is typically maintained at a level equivalent to 6,000–8,000 feet, which has no physical effect on the integrity of the implant shell. However, passengers who have recently undergone surgery (within 1–3 weeks) may experience increased swelling, tightness, or discomfort during a flight due to gas expansion in the body or the natural effects of altitude on healing tissues. Additionally, the risk of Deep Vein Thrombosis (DVT) is higher shortly after any surgery, so travelers are often advised to wear compression stockings and walk the aisles. For the vast majority of travelers with healed implants, flying is perfectly safe and involves no risk of rupture or change in the implant's shape or size.
