@Laotionne - @Animandel is correct about the chances of developing gallbladder cancer being very very slim. This is why I was surprised when a work friend of mine was diagnosed with the disease. She had been having problems with her gallbladder, including infections and pain, but the thought that she might have cancer never entered out minds. We knew the condition was rare.
One thing I learned from my friend's experience is that women need to be more aware of what is going on with their gallbladders. For whatever reason, gallbladder cancer is so much more likely to be found in women than in men.
The outcome for my friend was good. The cancer was caught relatively early, before it had a chance to advance into the later stages. She had radiation treatment, which was no picnic, but she came through great.
