Re: Mass in mom's kidney
90+ percent of kidney tumors are malignant, and even if the tumor lands in the 10% that are benign, they all must be removed-either before they spread, or, before further damage is done to the kidney and the surrounding tissues.
At that size, if it hasn't spread, there is a high possibility it could. Therefore, a quick treatment is recommended as once this cancer metastasizes the survival rate plummets.
Best of luck to you and your mom!
