Adenomas are benign tumors that arise from glandular tissue, which is responsible for producing and secreting substances in the body. They can develop in various organs, including the pituitary gland, thyroid, adrenal glands, and colon. Although adenomas are not cancerous, they can sometimes cause health issues by producing excess hormones or obstructing normal organ function. Diagnosis of adenomas typically involves imaging tests, such as CT scans or MRIs, and sometimes a biopsy to confirm their nature. Treatment options may include monitoring, medication, or surgical removal, depending on the size and symptoms associated with the adenoma. Regular check-ups are important to manage any potential complications.
