3 cm adrenal tumor without Cushings diagnosis

There doesn’t seem to be a good place to ask about this.

There is more adrenal tumor information here than Reddit endocrinology .

I’ve had a 3 cm tumor (not sure of the medical descriptive specific type of it., ) For about five years. It was an accidental discovery (MRI then later CT scan ) when I was having unrelated digestive problems. It has remained the same size. This is under the same endo doctor’s “supervision.”

My cortisol levels are still within range, but at the upper end of the range. That’s also been the same for five years. That might even be normal for me. I don’t know.

Just wondering how common this is to not have symptoms yet .

(as a late 50s guy who lives alone, I’m kind of freaked out to have the operation, but I realize I will probably need it sooner or later).
