Pheochromocytoma diagnosis..do I wait?

So a CT Scan I did a few weeks ago led to an incidental finding of Pheochromocytoma. Because of the size of the tumor; I’ve been advised that taking it out is most ideal. It is however not an emergency; I am not exhibiting any symptoms of concern. I’ve just talked to the doctor about the risks with the surgery especially as if releases hormones during surgery and I’m terrified! Should I just wait..no urgency now right?
