Advanced kidney cancer evaluation and treatment planning.
Health Orlando Urology provides thoughtful care for kidney masses, renal tumors, and kidney cancer concerns, with a focus on accurate diagnosis, clear answers, and kidney-preserving treatment planning when appropriate.
Kidney cancer, also called renal cancer, often begins as a tumor in the kidney. The most common type in adults is renal cell carcinoma. Many kidney tumors are found incidentally on imaging, which makes timely urologic evaluation especially important.
What is kidney cancer?
Kidney cancer begins when cells in the kidney grow abnormally and form a tumor. The most common adult kidney cancer is renal cell carcinoma, often called RCC.
Some kidney cancers are found after symptoms appear, but many are discovered unexpectedly during imaging for another condition. If a kidney mass appears on ultrasound, CT, or MRI, a urologic evaluation helps determine whether it is benign, suspicious, or likely cancerous.
Possible kidney cancer symptoms
Kidney cancer may not cause symptoms in the early stages. When symptoms occur, they can overlap with kidney stones, infection, back problems, or other urologic conditions.
Symptoms to discuss
- Blood in the urine
- Pain in the side, flank, or back
- A lump or mass in the side or abdomen
- Unexplained weight loss
- Loss of appetite
- Fatigue or persistent tiredness
When to seek care
- Visible blood in the urine
- Persistent flank pain
- Unexplained imaging finding
- Unexplained weight loss with urinary symptoms
- Known kidney mass needing evaluation
- Family history of kidney cancer
Kidney cancer causes and risk factors
Kidney cancer can develop without a clear cause, but several factors may increase risk. Having a risk factor does not mean you will develop kidney cancer, and some people diagnosed with kidney cancer have no obvious risk factors.
Smoking
Smoking is a known risk factor for kidney cancer and many other cancers. Quitting smoking can improve overall health and may reduce cancer risk over time.
Excess body weight
Obesity is associated with an increased risk of kidney cancer and can also affect surgical planning, blood pressure, and kidney health.
High blood pressure
Hypertension is linked with kidney cancer risk and should be managed carefully to protect long-term kidney and heart health.
Long-term dialysis
People on long-term dialysis or with certain kidney conditions may have a higher risk and may require specialized monitoring.
Genetics and inherited syndromes
A family history of kidney cancer or certain inherited conditions can increase risk. Genetic counseling may be appropriate in select cases.
Workplace or chemical exposure
Certain occupational or chemical exposures may play a role. Your physician may ask about work history and environmental exposures.
How kidney cancer is diagnosed
Evaluation typically begins with a review of imaging, symptoms, medical history, kidney function, and risk factors. The goal is to determine the size, location, and behavior of the kidney mass and whether it appears confined to the kidney.
Imaging review
Ultrasound, CT scan, or MRI can help show the size, location, and features of a kidney tumor or renal mass.
Blood and urine testing
Testing may assess kidney function, blood counts, urine findings, and overall health before treatment planning.
Staging evaluation
Additional imaging may be used to determine whether cancer appears confined to the kidney or has spread to nearby structures or distant areas.
Biopsy in select cases
A biopsy is not required for every kidney mass, but it may be considered when the diagnosis is uncertain or when it could change treatment planning.
Kidney cancer treatment options
Treatment depends on tumor size, location, stage, kidney function, overall health, and whether the cancer has spread. Many kidney cancers are treated with surgery, but not every patient needs the same approach.
Active surveillance
Some small kidney masses may be monitored closely with scheduled imaging, especially in patients where treatment risks may outweigh immediate benefits.
Partial nephrectomy
Partial nephrectomy removes the tumor while preserving as much healthy kidney tissue as possible. This may be an option for certain smaller or favorably located tumors.
Radical nephrectomy
Radical nephrectomy removes the entire kidney and may be recommended when the tumor is large, complex, or not suitable for kidney-sparing surgery.
Ablation
Cryoablation or radiofrequency ablation may be considered for select small tumors, particularly when surgery carries higher risk.
Systemic therapy
If kidney cancer has spread, treatment may involve immunotherapy, targeted therapy, or oncology coordination.
Radiation for symptom control
Radiation is not usually the main treatment for localized kidney cancer, but it may help manage symptoms if cancer has spread to certain areas.
Surgery, kidney preservation, and minimally invasive care
When surgery is recommended, the goal is to remove the cancer while preserving kidney function whenever safely possible. Your physician will consider the tumor’s size, depth, location, complexity, and relationship to nearby structures.
Partial nephrectomy
This approach removes the tumor and a margin of tissue while leaving the rest of the kidney in place. It may help preserve kidney function in appropriate candidates.
Nephrectomy
In some cases, removing the entire kidney is the safest or most effective option, especially for larger or more complex tumors.
Laparoscopic or robotic approach
Some kidney cancer surgeries may be performed using minimally invasive techniques, which may reduce incision size and support recovery in select patients.
Treatment planning
The best option depends on cancer features, kidney function, anatomy, medical history, and your long-term health goals.
Follow-up after kidney cancer treatment
Follow-up care is important after kidney cancer treatment. Your monitoring plan may include imaging, kidney function testing, urine testing, blood work, and visits to review recovery and recurrence risk.
Why follow-up matters
Ongoing monitoring helps evaluate kidney function, detect recurrence, and guide additional treatment if needed.
What follow-up may include
Depending on your diagnosis, follow-up may include CT, MRI, ultrasound, chest imaging, blood tests, and coordinated care with oncology.
Kidney cancer FAQ
What is the most common type of kidney cancer?
The most common type of kidney cancer in adults is renal cell carcinoma, often called RCC.
Does kidney cancer always cause symptoms?
No. Kidney cancer may not cause symptoms early. Many kidney tumors are found during imaging for another reason.
What symptoms should I watch for?
Symptoms can include blood in the urine, flank or back pain, unexplained weight loss, loss of appetite, fatigue, fever, or a lump in the side or abdomen.
Can kidney cancer be treated without removing the whole kidney?
In some cases, yes. Partial nephrectomy or ablation may be options for select patients, depending on tumor size, location, kidney function, and overall health.
Is a kidney biopsy always needed?
Not always. Many kidney tumors are evaluated primarily with imaging. Biopsy may be considered if the diagnosis is uncertain or if the result could change treatment decisions.
What should I bring to a kidney cancer consultation?
Bring imaging reports, imaging discs or links, blood work, urine test results, medication lists, prior surgical records, and any oncology or urology notes.
