4 years back I had adrenal tumor (11cms. Benign)and had the gland removed. Any chance of it recurring with the other gland.? Thnks

Adrenal adenoma. It is possible that you would get a new adenoma in the other adrenal gland.
Depends. There are certain types of benign adrenal growths which can recur on the opposite site, but this is rather unusual.
