Silent tumors may still harm the heart, new study warns

This study looks at people with rare adrenal tumors (pheochromocytomas and paragangliomas) that do not produce excess hormones. Researchers want to see if these 'silent' tumors still cause heart problems, blood pressure changes, or metabolic issues like diabetes and high cholesterol. They will compare 50 patients to healthy people and those with hormone-producing tumors, tracking changes before and after surgery or other treatments.
