Guide To The Major Types Of Kidney Cancer And Tumors

Renal Adenoma

A renal adenoma is one of the most common benign kidney tumors, though they are not common in the overall population. In most cases, these tumors are no larger than two to three centimeters in size. Symptoms can be nonspecific, and may not always appear, though they can include high blood pressure, weakness, low potassium, high blood sugar, bruising, excessive hair growth, and abnormal weight gain or loss.

The cause of these tumors is largely unclear, but many professionals believe that genetic conditions, such as multiple endocrine neoplasia, type 1, are involved. Unfortunately, it is difficult to differentiate renal adenomas from cancerous tumors. Thus, diagnosis and treatment are vital. In the majority of cases, surgical excision is the only effective method of both diagnosing and treating renal adenomas.
