The thickening of the adrenal gland can be a symptom of cancer. If it is not the result of cancer then typically it is ignored and looked at five or six months later.

That is the Adrenal gland. Another name for this is the Suprarenal gland.

The Adrenal Gland.

This gland is divided into two categories, the Adrenal Cortex and the Adrenal Medulla.

The Adrenal Medulla produced epinephrine and norepinephrine.

Epinephrine is also known as adrenaline, and the beginning of the word, "adrenal", is the same name as the gland, The Adrenal Gland.

The adrenal cortex, where aldosterone is produced, is part of the adrenal gland.

It is produced and secreted by the cortex (outer layer) of the adrenal glands which sit atop your kidneys.
