Adrenocortical carcinoma is a rare cancer, which comes from the adrenal gland. There are two adrenal glands in the human body, one on the top of each kidney in the abdomen. They are shaped like triangles, and each is about a ½ inch high and 3 inches long.
There are two main types of adrenocortical cancer:
Functioning is the most common type and accounts for about 70 percent of adrenal cancers. These tumors are "functioning" because they make hormones, which may have various effects on the body such as facial hair growth, increased blood pressure, or weight gain.
Non-functioning tumors do not produce hormones.
Adrenocortical carcinoma is a rare cancer, affecting only about 300 to 500 people each year in the United States.
