Symptoms of Non-Functioning Tumors
Symptoms of adrenal cancer may be caused by the tumor growing very large and pressing on nearby structures in the abdomen, or by excess hormones produced by the tumor. Symptoms of non-functioning tumors may include:

A lump in the abdomen

Abdominal pain

A feeling of fullness in the abdomen
Symptoms of Functioning Tumors
Functioning tumors produce excess hormones, including cortisol, aldosterone, testosterone, and estrogen. The symptoms caused by these tumors depend on the specific hormone produced.
