Are most kidney lesions benign?

Types of benign kidney tumors include: Renal adenoma – Renal adenomas are the most common form of benign, solid kidney tumor, and are typically small, low-grade growths. Their cause is unknown. Renal oncocytoma – Oncocytoma is a benign, usually asymptomatic tumor that can grow quite large.

Do benign kidney tumors need to be removed?

A non-cancerous (benign) tumour of the kidney is a growth that does not spread (metastasize) to other parts of the body. Non-cancerous tumours are not usually life-threatening. They are typically removed with surgery and do not usually come back (recur).

What percentage of kidney lesions are cancerous?

About 20-30% of “suspicious” kidney tumors when removed prove to be benign! These benign growths include cysts, oncocytomas, angiomyolipomas, and mixed epithelial stromal tumors. Thus, 70-80% of these “small” kidney tumors are cancers and fortunately the majority are “well behaved” (low grade) cancers.
