Adrenal Tumors

Overview

Adrenal tumors are growths that form in the adrenal glands, located above each kidney. They may be non‑functioning (not producing hormones) or functioning, meaning they secrete excess hormones such as cortisol, aldosterone, or adrenaline. Most adrenal tumors are benign adenomas, but some may be malignant, including adrenocortical carcinoma or metastatic disease. Symptoms depend on whether the tumor produces hormones and may include high blood pressure, weight gain, anxiety, or metabolic changes. Treatment varies based on tumor size, hormone activity, and imaging characteristics.

Causes

Causes include genetic mutations, hormonal overproduction, inherited syndromes (such as MEN or Lynch syndrome), and sporadic growth of adrenal tissue. Many adrenal tumors occur without a known cause.

Risk Factors

Risk factors include family history of endocrine tumors, genetic syndromes, long‑standing hypertension, obesity, and certain hereditary cancer conditions.

How Adrenal Tumors Affect the Body

Functioning tumors may produce excess hormones, leading to conditions such as Cushing’s syndrome, primary hyperaldosteronism, or pheochromocytoma. Non‑functioning tumors may cause symptoms only when large enough to compress nearby structures.

Complications

Complications include severe hypertension, electrolyte imbalances, metabolic disorders, heart strain, and in rare cases, malignant spread.

Symptoms & Signs

Symptoms depend on hormone activity and may include high blood pressure, rapid heartbeat, weight gain, fatigue, anxiety, sweating, headaches, abdominal pain, or unexplained metabolic changes.

Diagnosis

Diagnosis includes CT or MRI imaging, hormonal blood and urine tests, adrenal vein sampling (in select cases), and evaluation by an endocrine or surgical specialist.

Differential Diagnosis

Includes kidney tumors, metastatic disease, hormonal disorders, thyroid disease, and benign adrenal adenomas.

Lifestyle Modifications

Patients may benefit from blood pressure control, reducing sodium intake, managing stress, and maintaining a healthy weight. These changes support overall health but do not replace medical treatment.

Treatment Options

Treatment depends on tumor type and may include minimally invasive adrenalectomy, medical management of hormone excess, or surveillance for small, non‑functioning tumors. Malignant tumors may require additional oncologic therapy.

When to See a Doctor

Seek evaluation if you experience unexplained high blood pressure, rapid heartbeat, weight changes, or symptoms of hormone imbalance.

When to Seek Treatment

Treatment is recommended when tumors produce excess hormones, are larger than 4 cm, show suspicious imaging features, or cause symptoms.

Long-Term Outlook

Long‑term outcomes are excellent for benign tumors. Patients with functioning tumors often experience significant improvement after surgery. Regular follow‑up is recommended for hormone monitoring.

Prognosis

Most benign adrenal tumors have an excellent prognosis after surgical removal. Outcomes for malignant tumors depend on stage and response to therapy.
