Advice..has anyone dealt with something similar?

I won't go into much detail except that my fiancé has been having issues for a few years now. Blood in urine and stool, pain, unexplained weight loss, extreme anxiety, tons of excessive burping. We recently found out he has tumors on his gall bladder, the largest is 8 mm. It was said that we should follow up and "watch it" because it's more likely to be cancerous should it get to 10 mm.. Well in our minds 8 is not very far from 10, which scares us very much. He then had a urine analysis done today and it came back abnormal for white blood cell count and granular cast - nobody has bothered explaining to us what either of these things mean yet though. So obviously this worries us as well. Has ANYONE had any experience with anything of this sort or know anything about this? I'm sure there may not be any medical professionals on here who will read this, I'm just looking for any type of information we can get that would be helpful.
