My gallbladder went on Monday

Hi, I'm having my gallbladder out on 7th May. Had an attack a few weeks ago was sent off for an ultrasound and found to have gallstones, 2 small ones stuck in the bile duct. My treatment has been 12 x weekly paclitaxel (finished early November), Herceptin 3 weekly for 12 months (finishing end of July), zometa every 6 months for 3 years and arimidex (started early November) for 5 years. Seems a bit of a coincidence to me.
