Pheochromocytoma is a rare tumor that usually develops in the adrenal glands, which are located on top of the kidneys. This tumor produces excess hormones called catecholamines, leading to symptoms like high blood pressure, rapid heart rate, and sweating. These symptoms can sometimes be mistaken for anxiety or panic attacks. Diagnosis often involves blood and urine tests to measure hormone levels, along with imaging studies like CT scans or MRI. Treatment typically includes surgical removal of the tumor, which can help restore normal hormone levels and alleviate symptoms. Early detection and treatment are crucial for a positive outcome.
