When I read this I had doubts that this was really true. However, I knew I had a way to prove it. My wife had a saline implant put in as part of her reconstructive surgery afer cancer. She also has a breast without an implant so we tried the experiment last evening. Her whole implant did glow just like in the pictures and when we held the flash light up to her breast without the implant very little glowing happened. One learns something every day.
