Easy does it there, fella. Cell pathology, as much as you clearly want it to be, isn't necessarily black and white. That's not part of the health care "racquet," and it's not a mercenary ploy to make more money, keep you sick, or sabotage you or your confidence. It's simply the fact that the cell samples they looked at on slides couldn't tell them without a doubt what the histological specifics were, at least not enough to provide you with the complete reassurance you were obviously needing. That's a perfectly common early pathological report. If you were asked to take slides of such tissue, you'd not have been able to tell anything further, either, most likely. No matter how advanced medicine is.

You might want to consider thanking your lucky stars that you had health care providers who were straight enough to tell you the truth at this stage instead of lie to you--and who've encouraged you be vigilant about watching the cyst for signs of future growth if you want to be particularly responsible about your health. Had someone called and told you, "Oh heck, yeah, TallCoolOne, you're all clear," and then that hadn't been the case later, THAT would have been a real mess.
