Introduction
Being diagnosed with a kidney tumor or kidney cancer can be overwhelming. Patients and families often search for a kidney cancer specialist who can help them understand the diagnosis, treatment choices, kidney function, and long-term care.
Kidney cancer is not one single condition. The most common type in adults is renal cell carcinoma (RCC), but several other types of kidney tumors can occur. Some kidney masses are benign and do not represent cancer, while others require further investigation and treatment.
The evaluation of suspected kidney cancer often involves a multidisciplinary team. A urologist or urologic oncologist generally manages the surgical aspects of kidney tumors, while an oncologist may provide cancer-directed systemic treatment when required. A nephrologist plays an important role in evaluating kidney function, managing associated kidney disease, protecting the remaining kidney function, and providing kidney care before and after cancer treatment.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, a super specialist nephrologist, provides specialist kidney evaluation and kidney-function management and can coordinate care with appropriate urology and oncology specialists when kidney cancer is suspected or diagnosed.
What Is Kidney Cancer?
Kidney cancer occurs when abnormal cells in the kidney grow uncontrollably and form a tumor.
The most common kidney cancer in adults is renal cell carcinoma.
Other kidney tumors include different subtypes of renal tumors, as well as tumors that may originate in the renal pelvis or other structures.
Not every kidney mass is cancerous. Imaging characteristics and, in selected cases, additional testing help doctors determine the nature of a kidney lesion.
Who Is a Kidney Cancer Specialist?
The term kidney cancer specialist may refer to different specialists depending on the patient's needs.
Urologist or Urologic Oncologist
A urologist with expertise in kidney tumors generally evaluates the structural kidney mass and performs procedures or surgery when required.
Treatment may include:
-
Partial nephrectomy
-
Radical nephrectomy
-
Ablation procedures
-
Evaluation of urinary tract involvement
Medical Oncologist
An oncologist may manage kidney cancer that requires systemic treatment.
Depending on the cancer type and stage, treatment may involve:
-
Immunotherapy
-
Targeted therapy
-
Other cancer-directed medicines
Nephrologist
A nephrologist specializes in kidney function and kidney-related medical conditions.
Nephrology care can be particularly important for patients who:
-
Have chronic kidney disease
-
Have one functioning kidney
-
Are undergoing treatment that may affect kidney function
-
Have high blood pressure or diabetes
-
Develop reduced kidney function after kidney surgery
Because kidney cancer care can involve multiple specialties, coordination between these doctors is often important.
Common Symptoms of Kidney Cancer
Kidney cancer may not cause noticeable symptoms in its early stages and is sometimes discovered incidentally during imaging performed for another reason.
When symptoms occur, they may include:
-
Blood in the urine
-
Persistent pain in the side or lower back
-
An abdominal lump or swelling
-
Unexplained weight loss
-
Persistent fatigue
-
Reduced appetite
-
Recurrent fever without an obvious cause
-
Night sweats in some patients
-
Anemia
These symptoms can also occur with other medical conditions and do not automatically mean that a person has kidney cancer.
Persistent or unexplained symptoms should be evaluated by a qualified healthcare professional.
What Causes Kidney Cancer?
There is no single cause of kidney cancer. Several factors may increase risk.
Important risk factors include:
Smoking
Tobacco exposure is associated with an increased risk of kidney cancer.
Obesity
Excess body weight is associated with a higher risk of developing certain kidney cancers.
High Blood Pressure
Long-term hypertension has been associated with an increased risk of kidney cancer and can independently affect kidney function.
Family History
Some inherited conditions can increase the risk of kidney cancer.
Genetic Conditions
Certain hereditary syndromes can predispose individuals to kidney tumors.
Occupational or Environmental Exposures
Certain long-term exposures may contribute to kidney cancer risk.
Having a risk factor does not mean that a person will definitely develop kidney cancer.
How Is Kidney Cancer Diagnosed?
Diagnosis usually begins with medical history, examination, laboratory testing, and imaging.
Medical Evaluation
The doctor may review:
-
Symptoms
-
Medical history
-
Family history
-
Smoking history
-
Current medications
-
Blood pressure
-
Previous kidney problems
Blood Tests
Blood investigations may include:
-
Serum creatinine
-
Estimated Glomerular Filtration Rate (eGFR)
-
Complete Blood Count (CBC)
-
Electrolytes
-
Liver function tests when clinically indicated
These investigations help assess overall health and kidney function.
Urine Tests
Urinalysis may help identify:
-
Blood in the urine
-
Protein
-
Infection
-
Other urinary abnormalities
Ultrasound
Kidney ultrasound may identify:
-
Solid kidney masses
-
Cysts
-
Kidney enlargement
-
Structural abnormalities
However, ultrasound alone may not always establish whether a mass is cancerous.
CT or MRI
Contrast-enhanced CT or MRI may provide more detailed information about:
-
Size of the kidney mass
-
Location
-
Enhancement characteristics
-
Involvement of surrounding structures
-
Possible spread to other areas
The choice of imaging depends on the patient's medical condition and kidney function.
Is a Kidney Mass Always Cancer?
No.
A kidney mass can be benign or malignant.
Examples of benign kidney lesions include certain cysts and other non-cancerous tumors.
Radiologists classify kidney lesions using imaging characteristics, and some lesions require surveillance while others require additional evaluation or treatment.
The management depends on:
-
Size
-
Location
-
Imaging appearance
-
Growth over time
-
Patient age
-
Overall health
-
Kidney function
-
Other medical conditions
A doctor should interpret the imaging report in the context of the individual patient.
Kidney Cancer Stages
Kidney cancer is generally staged according to how large the tumor is and whether it has spread beyond the kidney.
Broadly, kidney cancer may be described as:
Localized Kidney Cancer
The cancer remains confined to the kidney.
Locally Advanced Kidney Cancer
The tumor has extended into nearby structures or lymph nodes.
Metastatic Kidney Cancer
The cancer has spread to distant organs.
Staging helps doctors determine the appropriate treatment strategy and prognosis.
Treatment Options for Kidney Cancer
Treatment depends on the type, stage, size, location, and characteristics of the tumor, as well as the patient's overall health.
Active Surveillance
Some small kidney masses may be monitored carefully instead of being treated immediately.
Follow-up imaging is used to monitor for changes in tumor size or characteristics.
Active surveillance may be considered particularly in selected patients where immediate treatment may carry greater risks.
Partial Nephrectomy
A partial nephrectomy removes the tumor while preserving as much healthy kidney tissue as possible.
When technically appropriate, preserving functioning kidney tissue can be important for long-term kidney health.
A urologist generally performs this procedure.
Radical Nephrectomy
A radical nephrectomy involves removal of the affected kidney and may be recommended for selected larger or more complex tumors.
After removal of one kidney, the remaining kidney takes over most kidney function, although long-term monitoring may be necessary.
Ablation
Selected small kidney tumors may be treated with techniques that destroy the tumor using heat or cold.
Examples include:
-
Cryoablation
-
Radiofrequency ablation
Whether ablation is appropriate depends on tumor characteristics and the patient's overall condition.
Systemic Cancer Treatment
For advanced or metastatic kidney cancer, treatment may involve medicines that work throughout the body.
Depending on the cancer subtype and clinical situation, treatment can include:
-
Immunotherapy
-
Targeted therapy
-
Combination treatment
An oncologist determines the appropriate systemic treatment.
Why Kidney Function Matters During Kidney Cancer Treatment
Protecting kidney function is an important part of comprehensive care.
Kidney function may be affected by:
-
Existing chronic kidney disease
-
Removal of part or all of a kidney
-
High blood pressure
-
Diabetes
-
Certain cancer treatments
-
Dehydration or other acute illnesses
Monitoring kidney function before and after treatment helps doctors identify changes early.
A nephrologist can assist with:
-
Kidney-function assessment
-
Blood pressure management
-
CKD management
-
Medication review
-
Management of electrolyte abnormalities
-
Long-term kidney health monitoring
Kidney Cancer Treatment When You Have Only One Kidney
Patients with a solitary functioning kidney require particularly careful planning.
Doctors may consider whether treatment can preserve as much functioning kidney tissue as safely possible.
Depending on the tumor and individual circumstances, options may include:
-
Active surveillance
-
Partial nephrectomy
-
Ablation
-
Other individualized approaches
A multidisciplinary team can balance cancer control with preservation of kidney function.
Kidney Cancer and Chronic Kidney Disease
Patients with chronic kidney disease may need additional consideration before undergoing imaging, surgery, or cancer treatment.
A nephrologist may assess:
-
Baseline eGFR
-
Protein in the urine
-
Blood pressure
-
Electrolytes
-
Diabetes control
-
Medication safety
-
Risk of acute kidney injury
This helps the treating team make decisions with kidney health in mind.
Follow-Up After Kidney Cancer Treatment
Regular follow-up is important after treatment.
Depending on the cancer stage and treatment, follow-up may involve:
-
Periodic imaging
-
Blood tests
-
Kidney function monitoring
-
Blood pressure checks
-
Urine testing
-
Cancer surveillance
-
Specialist consultations
The follow-up schedule is individualized according to the cancer diagnosis and treatment.
How to Protect Kidney Health During Cancer Care
Patients can support their kidney health by:
-
Monitoring blood pressure regularly
-
Managing diabetes effectively
-
Avoiding unnecessary painkillers, particularly NSAIDs when kidney function is reduced
-
Taking medicines exactly as prescribed
-
Staying adequately hydrated according to medical advice
-
Avoiding smoking
-
Maintaining a healthy body weight
-
Attending kidney function follow-ups
-
Informing doctors about existing kidney disease before imaging or treatment
Do not start supplements or herbal products without discussing them with your healthcare team.

Frequently Asked Questions
Which doctor should I see for kidney cancer?
A urologist or urologic oncologist generally evaluates and manages kidney tumors and surgical treatment. A medical oncologist manages systemic cancer treatment when required. A nephrologist focuses on kidney function and associated kidney disease.
Can a nephrologist treat kidney cancer?
A nephrologist does not usually perform kidney cancer surgery or provide the primary cancer treatment. However, nephrology care can be important for protecting kidney function before and after treatment, particularly in patients with CKD or a single functioning kidney.
Can kidney cancer be cured?
Some localized kidney cancers can be treated successfully, particularly when detected early. The likelihood of long-term control depends on the cancer type, stage, tumor characteristics, and individual health.
Does kidney cancer always cause pain?
No. Kidney cancer can be present without pain, particularly during earlier stages. Some patients are diagnosed incidentally during imaging performed for another reason.
Is blood in the urine always a sign of kidney cancer?
No. Blood in the urine can have many causes, including urinary infections, kidney stones, prostate conditions, and other urinary tract disorders. However, unexplained blood in the urine should be medically evaluated.
Can kidney cancer treatment damage kidney function?
Some treatments, including removal of kidney tissue, may reduce overall kidney function. Other medical factors can also affect kidney health. Kidney function monitoring is therefore important during and after treatment.
What happens if kidney cancer affects one kidney?
If the other kidney is healthy, it can often provide most of the body's required kidney function after removal of the affected kidney. However, ongoing monitoring of kidney function and blood pressure remains important.
Conclusion
Choosing the right kidney cancer specialist depends on the patient's specific needs. Kidney tumors are generally evaluated and treated through a multidisciplinary approach involving urology, oncology, radiology, and, when appropriate, nephrology.
A suspicious kidney mass does not automatically mean cancer, and the appropriate diagnosis requires medical evaluation and suitable imaging. When kidney cancer is confirmed, treatment may include active surveillance, partial nephrectomy, radical nephrectomy, ablation, systemic cancer therapy, or combinations of these approaches depending on the individual case.
