Could a kidney tumor be benign?

Kidney tumors can be benign.

Kidney tumors are tumors that occur in the kidneys, both benign and malignant. Benign tumors are relatively rare, but do exist. Common benign kidney tumors include angiomyolipoma, renal adenoma, and renal cyst. These benign tumors usually grow slowly, do not invade surrounding tissues or metastasize to other sites, and in most cases do not cause obvious symptoms.

However, even benign tumors, if they grow large enough, may cause pressure on the kidneys or surrounding organs, causing pain, bleeding, or other complications. Therefore, if a kidney tumor is found, whether benign or malignant, it should be promptly evaluated and treated by a professional.
