My husband (71, former smoker) had a stent placed yesterday for a kidney stone that's blocking the ureter. Urologist said he found a 2 cm tumor, removed it and sent it to pathology, we'll know in a few days. He said it looked "low grade" to him. Low grade as in, it is cancer but not aggressive? Or low grade as it could be benign? He seemed to think it was probably not benign since my husband is older and former smoker. My husband doesn't have any symptoms other than has had intermittent microscopic blood in urine from the stone (2.5 cm!).
If no symptoms, does this mean it's less serious?
