How to diagnose Renal oncocytoma ?
How is renal oncocytoma diagnosed? A diagnosis of renal oncocytoma is often suspected based on imaging studies such as computed tomography (CT scan) and/or magnetic resonance imaging (MRI scan). However, it can be difficult to differentiate a renal oncocytoma from renal cell carcinoma based on imaging studies alone. Although researchers are currently studying several new techniques for the diagnosis of renal oncocytoma, a biopsy and surgery are typically necessary to confirm the diagnosis. Is genetic testing available for renal oncocytoma? Genetic testing is not available for many people with renal oncocytoma since most of these tumors occur sporadically (by chance) and are not caused by a genetic mutation. However, genetic testing is an option for people with an inherited condition that predisposes to renal oncocytoma such as tuberous sclerosis complex and Birt-Hogg-Dube syndrome. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. It provides a list of laboratories performing genetic testing for tuberous sclerosis complex and Birt-Hogg-Dube syndrome. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.
