A hypernephroma is the most
commonCommon cold form of kidney cancer which occurs when the cells lining the renal tubule undergo cancerous changes.
An oncocytoma is the most common benign solid renal tumor.
A kidney cyst would be another type of benign kidney lesion.
If there is strong clinical suspicion that the kidney mass is cancerous (malignant), surgical removal of the kidney will be considered. If it is not clear, a biopsy must be performed. During a biopsy procedure a small tissue sample is removed from the mass and examined to determine whether it is benign or malignant.
I would suggest a referral to a urologist for further evaluation.
Followup with your personal physician is essential.
