Short Summary
Main recommendation: Adrenal nodules found incidentally on imaging are usually benign, but they need evaluation by a doctor who checks for hormone overproduction and signs of cancer before deciding on treatment. The video explains that treatment depends on whether the nodule is hormonally active or looks suspicious for cancer, and that biopsy is usually not recommended.
Key Points
- Adrenal nodules (adrenal incidentalomas) are growths found on scans ordered for unrelated problems, and they are very common, with up to 7 percent of people by age 70 having one.
- Most adrenal nodules are benign and do not cause problems, but a small number can cause serious disease.
- Treatment is generally needed if there are signs of cancer or if the nodule produces too much hormone, which is checked with blood and urine tests.
- Cancer suspicion is assessed with a special adrenal CT scan looking at size, density, and borders, though some cancers are small, so the whole picture matters.
- Biopsy is usually not helpful or needed, and can be dangerous because a hormone-secreting (adrenaline-producing) tumor can suddenly release a large amount and raise blood pressure to dangerous levels.
Details Worth Noting
- Concrete instructions: If an adrenal nodule appears on a scan, talk with your doctor about it rather than assuming it is harmful. Ask your doctor to order blood and urine tests checking for excess hormones: steroid oversecretion (Cushing syndrome) and hormones related to blood pressure control, including adrenaline and aldosterone. Ask whether a special adrenal-focused CT scan is needed to evaluate size, density, and borders. Do not request an adrenal biopsy routinely; it is generally reserved for cases where the nodule may be cancer that spread from another part of the body. For tumors that are hormone-producing, surgery to remove the adrenal gland and tumor is offered to most patients, according to Dr. Harare. For non-functional tumors with suspicious imaging, removal should be considered. If a non-functional tumor is not removed, it needs close follow-up with scans and repeat lab levels, since up to 20 percent may begin making too much hormone or grow.
- Adrenal glands sit above each kidney and produce hormones controlling metabolism, blood pressure, immune function, and stress response.
- Cancers are typically larger than 6 centimeters, very dense, and have irregular borders, though some small cancers exist.
- Adrenaline-producing tumors are called pheochromocytomas and can cause serious body changes requiring medical or surgical treatment.

Bottom Line
Finding an adrenal nodule on a scan is common and usually not dangerous, but it warrants a hormone workup and imaging review with a specialist to rule out a functioning tumor or cancer before deciding whether to monitor or remove it.
