Guide To The Major Types Of Kidney Cancer And Tumors

Oncocytoma

Some individuals may deal with a renal oncocytoma. This kidney growth, thankfully, is usually benign, though rare cases can be cancerous. Patients often discover oncocytomas when they need diagnostic imaging for other conditions, since symptoms are not common. However, renal oncocytomas can result in a variety of symptoms in certain cases. These symptoms include blood in the urine, a mass in the abdomen, as well as abdominal or flank pain.

These growths are more common in men over fifty years old, though anyone can develop them. Single renal oncocytomas have an unknown cause, though when they affect both kidneys, genetic conditions appear to be involved. If the patient's tumor is benign, it likely does not require treatment. However, if it does cause symptoms, patients often receive surgery. This also allows doctors to confirm the diagnosis.
