Treating Adrenal Incidentalomas What Are Your Options
Treating adrenal incidentalomas starts with checking hormone output and cancer risk, then choosing monitoring or surgery. Get labs and guidance—no referral.
An adrenal incidentaloma is a growth on your adrenal gland that shows up “by accident” on a scan done for something else. Most are benign and never cause trouble, but you still need two questions answered: is it making extra hormones, and does it look risky for cancer. The good news is that the decision tree is usually clear once the right tests are done. This article walks you through the symptoms that suggest hormone activity, what imaging features matter, which labs are commonly used, and how doctors decide between watchful monitoring and surgery. If you want help interpreting results or planning next steps, PocketMD can talk it through with you, and VitalsVault labs can support the hormone testing your clinician may recommend.
Symptoms and signs that matter
No symptoms at all (very common)
Many adrenal incidentalomas do not cause any symptoms because they are not producing hormones and they are too small to press on anything. That can feel unsettling, because you have “a mass” but no clues from your body. In this situation, the scan details and a focused hormone check are what guide the plan.
Hard-to-control blood pressure
If your blood pressure stays high despite medication, an adrenal growth that makes stress hormones or salt-retaining hormones can be part of the story. You might notice headaches, a pounding heartbeat, or feeling “wired” at odd times. This matters because treating the hormone source can sometimes improve blood pressure more than simply adding another pill.
Low potassium symptoms
Some adrenal nodules lead to low potassium through excess aldosterone, which is a hormone that tells your kidneys to hold onto salt and dump potassium. Low potassium can show up as muscle cramps, weakness, or heart palpitations that feel scary and random. Even mild, repeated low potassium is a clue worth bringing up because it changes which tests you need.
Cortisol excess body changes
Extra cortisol can be obvious, but it is often subtle and slow, which is why people miss it. You might gain weight around your middle, bruise easily, feel weaker climbing stairs, or notice rising blood sugar and blood pressure. The “so what” is that long-term cortisol excess raises your risk for diabetes, bone loss, and heart disease, even if you do not feel dramatically ill.
Red flags that need urgent care
Severe, sudden headache with very high blood pressure, chest pain, shortness of breath, fainting, or a racing heartbeat that will not settle can signal a dangerous hormone surge. Rarely, bleeding into an adrenal mass can cause sudden flank or abdominal pain with dizziness. If any of those are happening, it is not a “wait for the next appointment” situation—get urgent evaluation.
If your clinician wants hormone testing, you can start with a starting from $99 panel with 100+ tests, one visit, then review results together.

Why adrenal incidentalomas happen (and who is at higher risk)
Benign adrenal adenoma
The most common cause is a benign growth called an adrenal adenoma, which is basically a small cluster of adrenal cells that grew a little differently. Many adenomas are “nonfunctioning,” meaning they do not make extra hormones. They still matter because you need to confirm they are quiet and that their imaging features fit a benign pattern.
Hormone-producing nodules
Some incidentalomas produce hormones even when you do not have classic symptoms, which is why testing is routine. Depending on the hormone, your body may be pushed toward higher blood pressure, higher blood sugar, anxiety-like surges, or low potassium. Identifying hormone activity is important because it often changes treatment from simple monitoring to targeted therapy or surgery.
Age and more imaging
Incidentalomas become more common as you get older, partly because small benign growths accumulate over time. They are also found more often simply because more people get CT and MRI scans for back pain, kidney stones, or abdominal symptoms. In other words, the “risk” is sometimes just being scanned.
History of cancer elsewhere
If you have had cancer before, an adrenal mass has a higher chance of being a metastasis, even though benign causes are still possible. That history changes how aggressively doctors interpret imaging and how quickly they move to additional scans or biopsy in select cases. The goal is not to panic—it is to avoid missing something that needs timely treatment.
Genetic and rare tumor risks
Certain inherited conditions can increase the chance of adrenal tumors that make hormones, including tumors that release adrenaline-like hormones. You might suspect this if you have a strong family history of endocrine tumors or if you have repeated episodes of sweating, pounding heartbeat, and spikes in blood pressure. When genetics are on the table, the workup often expands because it affects your long-term follow-up and your family’s risk, too.
How doctors diagnose and sort risk
Reading the scan for benign clues
The first step is usually a careful look at the CT or MRI characteristics, not just the size. Radiologists look for features that suggest a fatty, benign adenoma versus something more suspicious, and they may recommend a dedicated adrenal-protocol scan if the original imaging was not designed for this. This matters because a mass that looks clearly benign often needs less follow-up.
Cortisol screening (even if you feel fine)
A common check is an overnight steroid suppression test (dexamethasone suppression test), which looks for cortisol that refuses to “turn off.” You might feel normal and still have mild cortisol excess that quietly raises blood pressure, blood sugar, and fracture risk. If this test is abnormal, your clinician will usually confirm with additional hormone testing and review your medications because some drugs can interfere.
Testing for adrenaline-like surges
To rule out a tumor that releases adrenaline-like hormones, clinicians often order plasma free metanephrines or urine metanephrines. This is especially important if you have episodic headaches, sweating, tremor, or sudden blood pressure spikes, but it can be done even without symptoms depending on imaging. It matters because certain medications and procedures can be risky if this diagnosis is missed.
Aldosterone and potassium evaluation
If you have high blood pressure—especially with low potassium—testing often includes an aldosterone-to-renin ratio, along with basic electrolytes. The tricky part is that some blood pressure medications change renin and aldosterone levels, so your clinician may adjust meds before testing. Getting this right can uncover a treatable cause of hypertension that is otherwise easy to label as “essential.”
Treatment options: monitoring, medication, and surgery
Watchful monitoring for low-risk nodules
If the mass looks benign on imaging and hormone tests are normal, the most common “treatment” is simply follow-up. That might mean a repeat scan at a set interval and periodic hormone checks, especially if the nodule is not tiny or if you develop new symptoms. Monitoring is not doing nothing—it is a plan to catch growth or hormone changes early without exposing you to unnecessary surgery.
Surgery when cancer risk is higher
Surgery is more strongly considered when imaging features look suspicious, when the mass is large enough to raise concern, or when it grows over time. The operation is called adrenal removal (adrenalectomy), and it is often done with minimally invasive techniques when appropriate. The “so what” is that removing a higher-risk mass can be both diagnostic and curative, but it should be balanced against surgical risks and your overall health.
Surgery for hormone-producing tumors
If the nodule is clearly making excess hormones, surgery may be recommended even if it looks benign, because the hormone effects can harm your heart, bones, and metabolism over time. The exact preparation depends on which hormone is involved, and some hormone-producing tumors require specific medications before surgery to keep you safe. After removal, you may need temporary hormone support while your body recalibrates.
Medication when surgery is not ideal
Sometimes surgery is not the best option because of other medical issues, personal preference, or because the hormone excess is mild. In those cases, treatment may focus on controlling the downstream effects, such as using specific blood pressure medicines for aldosterone excess or managing diabetes and bone health when cortisol is elevated. This approach works best when you and your clinician agree on what you are treating and how you will track progress.
Follow-up after treatment or observation
Whether you monitor or treat, follow-up is about two things: making sure the mass is stable and making sure your hormones stay in a safe range. If you have an adrenal removed, you may need testing to confirm the remaining gland is carrying the load, especially if you feel fatigue, nausea, dizziness, or unusual weakness. If you are observing, new symptoms like worsening blood pressure or unexplained low potassium are a reason to re-check hormones sooner.
Living with an adrenal incidentaloma
Track the changes that actually matter
A simple log can help you notice patterns that point toward hormone activity, such as blood pressure spikes, new headaches, or episodes of sweating and tremor. You do not need to track everything—focus on what would change your workup or treatment plan. Bringing a short, clear timeline to appointments often speeds up decisions.
Make your medication list part of the plan
Some medications and supplements can affect hormone tests, and some blood pressure drugs can complicate aldosterone testing in particular. Before you stop anything, ask your clinician what should be held and what must be continued for safety. This matters because a “false normal” result can delay the right treatment, while a “false high” result can lead to unnecessary worry.
Protect your heart and bones while you wait
Even when the nodule is likely benign, the workup period can take weeks, and mild hormone excess can quietly add strain. Prioritizing sleep, movement you can sustain, and consistent blood pressure monitoring gives you something concrete to do while decisions are made. If cortisol excess is suspected, ask specifically about bone health and blood sugar, because those are common places it shows up first.
Know what follow-up questions to ask
It helps to ask your clinician what the scan suggests, which hormone tests were done, and what result would trigger surgery versus monitoring. You can also ask what interval they recommend for repeat imaging and whether you need repeat hormone testing even if the first round is normal. Clear thresholds reduce the anxiety of “watching and waiting.”
Prevention: what you can and can’t control
You can’t prevent most incidentalomas
Most adrenal incidentalomas are not caused by something you did, and there is no proven way to prevent them from forming. That is frustrating, but it also means you should not blame yourself. What you can control is getting the right evaluation so a harmless finding stays harmless.
Lower the impact of silent hormone excess
If your nodule is associated with mild hormone changes, prevention becomes about reducing the damage those hormones can do. Keeping blood pressure, blood sugar, and cholesterol in a healthy range lowers long-term risk even before a final decision about surgery is made. Small steps add up when the hormone effect is slow and chronic.
Avoid missed follow-up
The biggest preventable problem is losing the thread after the initial scan report. Put the follow-up imaging date and lab plan somewhere you will actually see it, and make sure you know who is coordinating care. This matters because growth or new hormone activity is usually fixable when caught early.
Family risk awareness when genetics are possible
If your clinician suspects a genetic syndrome based on your history or tumor type, prevention includes family awareness and appropriate screening. That can feel heavy, but it is also empowering because it turns a surprise finding into a plan. If genetics are not suspected, you usually do not need to worry about your family members developing the same issue.
Frequently Asked Questions
What is an adrenal incidentaloma, and should you be worried?
An adrenal incidentaloma is a growth on your adrenal gland found unexpectedly on imaging. Most are benign and nonfunctioning, which means they do not make extra hormones. You should take it seriously enough to get the recommended hormone tests and imaging review, because that is how you separate “common and harmless” from “needs treatment.”
How do doctors decide between monitoring and surgery?
The decision usually comes down to whether the mass is producing hormones and whether imaging features suggest a higher cancer risk. A benign-looking, nonfunctioning nodule is often monitored with repeat imaging and sometimes repeat labs. A hormone-producing mass or one with concerning imaging features is more likely to be treated with adrenalectomy.
Can an adrenal incidentaloma cause weight gain or anxiety?
It can, but only if it is producing hormones. Extra cortisol can drive weight gain, muscle weakness, and higher blood sugar, while adrenaline-like hormone surges can feel like panic with sweating and a racing heart. Because these symptoms overlap with common conditions, hormone testing is the way to confirm whether the adrenal nodule is actually the cause.
What labs are typically checked for an adrenal incidentaloma?
Common testing looks for cortisol excess, adrenaline-like hormone excess (metanephrines), and aldosterone-related hypertension when appropriate. Your clinician may tailor the lab list based on your blood pressure, potassium level, and scan features. If you are arranging testing, VitalsVault lab options can support this workup, including a starting from $99 panel with 100+ tests, one visit, with results to review with your clinician.
If you remove one adrenal gland, will you need lifelong hormones?
Many people do fine with one adrenal gland because the remaining gland can usually make the hormones your body needs. However, if the removed gland was suppressing the other side or if cortisol was involved, you may need temporary steroid replacement while your body recovers. Your surgeon and endocrinology team will guide follow-up testing based on your symptoms and the pathology results.
