Adrenal Gland Tumors: Benign vs Malignant and What to Do Next
By Dr. Gajendra Kumar Himanshu
Adrenal gland tumors are lumps that form in the adrenal glands. The adrenal glands are tiny glands on top of each kidney. These glands create vital hormones that assist in regulating blood pressure, metabolism, stress response, and many other bodily functions. When an adrenal tumor is identified, one of the first concerns that patients and families ask is whether it is benign (non-cancerous) or malignant (cancerous).
The good news is that many adrenal gland tumors are benign and may not need immediate treatment. However, some tumors might produce too many hormones or become malignant; therefore, appropriate diagnosis is quite crucial. Understanding what benign and malignant adrenal tumors are, the tests used to diagnose them, and the treatment choices available can help people make informed decisions and partner with their healthcare team to determine the best next steps.
In this blog, we will discuss the difference between benign and malignant adrenal gland tumors, their symptoms, diagnosis, treatment choices, and what patients should do following diagnosis.
Understanding the Function of the Adrenal Glands
The adrenal glands are little yet mighty structures that sit atop the kidneys. They make hormones that help control several critical physiological functions, including:
- Blood pressure
- Pulse rate
- Stress reaction
- Blood glucose
- Metabolism
- Salt and water balance
A tumor in the adrenal gland may or may not disrupt hormone production.
Benign vs Malignant Adrenal Tumors: What’s the Difference?
Not all adrenal tumors are malignant. In fact, many are found incidentally on imaging studies done for other medical reasons.
Benign Tumors of the Adrenal Gland
Benign (noncancerous) tumors do not spread to other regions of the body. Some do not grow and create no symptoms. The common forms of benign adrenal tumors are:
- Adrenal adenomas
- Myelolipomas
- Benign hormone-releasing tumors
These tumors are not malignant, but some can make too much hormone and need treatment.
Adrenal Cancer
Cancerous tumors are malignant and may develop into adjacent tissue or spread to other parts of the body. Examples are:
- Adrenal cancer
- Metastatic cancer that has spread to the adrenal glands
- Rare malignancies of the adrenals
Because malignant tumors might behave differently from benign tumors, early examination and competent medical care are necessary.
Symptoms That May Indicate an Adrenal Gland Tumor
Some adrenal tumors have no symptoms at all. Others may create additional hormones that cause obvious changes in the body.
Symptoms may include:
- High blood pressure
- Unexplained weight gain
- Unexplained weight loss
- Weakness of muscles
- Frequent headaches
- Sweating excessively
- Fast heart rate
- Tiredness
- Nervousness or anxiety
- Pain in the abdomen or back
The symptoms depend on the type of hormone that’s being produced and the size of the tumor.
How Do Doctors Know Whether a Tumor is Benign or Malignant?
Doctors do a number of tests to find out more about the tumor and determine the best treatment option.
Hormone & Blood Testing
Blood and urine tests help doctors determine whether the tumor is producing excess hormones. These tests may include evaluation of:
- Cortisol concentrations
- Aldosterone concentrations
- Adrenaline hormones
- Other hormonal markers
Radiologic Studies
Imaging examinations can show the size, form, and features of the tumor. The most common imaging techniques are:
- CT scan
- MRI scan
- PET scan in selected cases
Tumors that are larger or have atypical imaging characteristics may need to be looked at more closely.
Genetic Testing and Biopsy
Sometimes doctors may want to undertake more tests to learn more about the tumor. Genetic testing may be considered, especially in the presence of:
- Family history of cancers
- Suspected inherited syndromes
- Unusual tumour behaviour

Treatment and Prognosis
Management | Objective |
|---|---|
Active monitoring | Watch small, stable tumours |
Medications | Manage hormone-related symptoms |
Surgery | Remove selected tumors when indicated |
Radiation Therapy | Treat certain malignant tumours |
Chemotherapy | Aid in the management of advanced cancer |
Targeted Therapy | Target cancers with certain molecular characteristics |
When Monitoring or Surgery May Be Needed
Many small benign tumors do not need to be treated right away. Your doctor might suggest:
- Routine imaging studies
- Regular blood testing
- Hormonal monitoring
- Follow-up visits
This helps ensure any changes are identified early.
When Surgery Might Be Recommended
Surgery may be considered in the following situations:
- The tumor is large
- Overproduction of hormones
- Suspected cancer
- Symptoms are interfering with the quality of life
That doesn’t mean that every adrenal tumor requires surgery. It depends on individual risk, family history, genetic testing findings, overall health, and the doctor's advice.
Treatment of Malignant Tumors
If the adrenal tumor is malignant, treatment may comprise a mix of therapies. Depending on the situation, doctors may suggest:
- Surgical procedure
- Chemotherapy
- Radiotherapy
- Targeted therapies
- Clinical trials participation
Treatment programs are meticulously customized to each individual’s condition and needs.
Coping With a Diagnosis of an Adrenal Tumor
Receiving news of an adrenal gland tumor can be upsetting, even when the tumor is benign. Many patients find these steps useful:
- Understanding the diagnosis clearly
- Asking questions at appointments
- Bringing a family member to appointments
- Maintaining records of test results
- Following the prescribed follow-up schedules
- Asking for emotional help when needed
Clear information can lessen ambiguity and help patients feel more secure about their next steps.

Frequently Asked Questions
No. Many tumors of the adrenal gland are benign and don’t spread to other parts of the body.
Yes. Some tumors can secrete too many hormones and lead to symptoms such as high blood pressure, headaches, weight changes, or tiredness.
No. Some small, benign tumors can be watched with regular check-ups and imaging studies.
To establish if a tumor is benign or malignant, doctors employ imaging scans, hormone tests, medical history, and occasionally extra testing.
