Kidney cancer
A mass was found on my kidney: what happens next?
By Advanced Urology · November 10, 2026
A mass was found on your kidney.
Summary
What happens next? First, take a breath.
Going through it
Many kidney masses are found by accident, and many are small. Some are benign. Next steps usually include a dedicated CT or MRI to see what the mass looks like, blood and urine tests, and sometimes a biopsy. Options range from watching small masses to ablation or surgery that can save most of the kidney.
When to schedule
If a scan mentions a kidney mass or complex cyst, schedule a visit so we can review the images with you.
At our Canton clinic
We see Canton patients at 2205 Riverstone Blvd Suite 101, where many first visits include testing. Your procedure is performed in Marietta, then your checkups come home to Riverstone Blvd.

Your first visit on Riverstone Blvd
Canton residents with a newly found kidney mass meet our urologists at our Canton office. Bring the scan report and, if possible, the images on disc. We'll explain what the mass looks like, how big it is, and whether it appears solid or fluid-filled, since that changes what comes next. Blood work to check kidney function is often part of the visit.
How our urologists plan next steps
Some masses are simple cysts that need nothing more than reassurance. Others call for more imaging, careful monitoring, ablation, or kidney-sparing surgery carried out by our urologists in Marietta. We'll explain each path and why we lean toward one for you.
Signs to report without delay
- Visible blood in the urine
- New pain in the side or back
- Fevers or night sweats
- Weight loss you can't explain
Questions Canton patients ask
Common questions
Does a mass always mean cancer?
No. Many kidney masses turn out to be cysts or noncancerous tumors. A CT or MRI with contrast shows whether the mass is solid and has blood flow, which decides whether to watch it, biopsy it or treat it.
Will I need a biopsy?
Not always. When imaging clearly shows a solid tumor, treatment can go ahead without one. A biopsy is used when the result would change the plan, such as before needle ablation or when a mass looks unusual.
