Adrenal adenomas are noncancerous tumors that develop in the cortex of the adrenal glands. The adrenal glands are located above the kidneys, writes Mayo Clinic. Most adrenal adenomas do not require treatment.
Surgery or medication, however, might be used to treat an adrenal adenoma that begins to produce high levels of certain hormones. This can be harmful because the adrenal glands produce hormones that control almost the entire body, according to Mayo Clinic. These hormones can cause high blood pressure, obesity, diabetes, headaches and panic attacks, notes the Dartmouth-Hitchcock Cancer Center. Men can experience breast growth and impotence because of the tumors, while women experience an increase in muscle mass and hair growth.
