Renal cancer, commonly called kidney cancer, develops when abnormal cells grow within the kidney.

The most common type of kidney cancer in adults is renal cell carcinoma, although several different types of kidney tumors can occur.

People searching for renal cancer treatment often want to know whether surgery is always necessary and what options are available when cancer has spread.

The answer depends on several important factors, including:

• Type of kidney cancer

• Size of the tumor

• Location within the kidney

• Whether cancer is confined to the kidney

• Whether nearby tissues or lymph nodes are involved

• Whether cancer has spread to distant organs

• Kidney function

• Condition of the other kidney

• Age and overall health

Renal cancer treatment is therefore individualized.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides specialist kidney-function evaluation and care for patients with kidney-related conditions. Patients diagnosed with renal cancer may require coordinated treatment with appropriate urology, uro-oncology and oncology specialists.

How Is Renal Cancer Treatment Decided?

A renal cancer treatment plan is usually developed after detailed evaluation.

Doctors may consider:

• Imaging findings

• Tumor size

• Tumor location

• Biopsy findings when appropriate

• Cancer stage

• Cancer type

• Kidney function

• Presence of cancer in the other kidney

• Previous kidney disease

• Other medical conditions

The goal may be to remove or destroy localized cancer while preserving as much healthy kidney tissue as safely possible.

For advanced or metastatic cancer, treatment may focus on controlling cancer growth, prolonging survival and managing symptoms.

Main Renal Cancer Treatment Options

Depending on the patient's diagnosis, treatment options may include:

• Active surveillance

• Partial nephrectomy

• Radical nephrectomy

• Ablative treatment in selected patients

• Immunotherapy

• Targeted therapy

• Other systemic cancer treatment

• Radiation therapy for selected situations

• Supportive and palliative care

Not every treatment is suitable for every patient.

Active Surveillance for Small Renal Tumors

Not every kidney tumor requires immediate surgery.

In selected patients with small renal masses, doctors may recommend active surveillance.

This approach involves regular monitoring using imaging and clinical follow-up.

Active surveillance may be considered depending on:

• Tumor characteristics

• Growth rate

• Age

• Overall health

• Surgical risk

• Kidney function

The purpose is to avoid unnecessary treatment while continuing to monitor the tumor for significant changes.

Partial Nephrectomy: Removing the Tumor and Preserving the Kidney

A partial nephrectomy removes the kidney tumor while preserving the remaining healthy part of the kidney.

This approach may be considered when technically and medically appropriate.

Partial nephrectomy can be particularly important when:

• The tumor is relatively localized

• The patient has reduced kidney function

• The patient has only one functioning kidney

• Tumors are present in both kidneys

• Preserving kidney tissue is an important clinical priority

The suitability of partial nephrectomy depends on the tumor's size, location and complexity.

Radical Nephrectomy

A radical nephrectomy involves removal of the entire affected kidney.

It may be recommended when the tumor is large, complex or located in a position where partial removal is not considered safe or effective.

After removal of one kidney, the remaining kidney may continue to provide sufficient filtration for many people.

However, kidney function should be monitored carefully, especially in patients who already have:

• Chronic kidney disease

• Diabetes

• High blood pressure

• Protein in the urine

• Reduced function in the remaining kidney

Why Kidney Function Matters Before Renal Cancer Surgery

Kidney cancer treatment should not focus only on removing the tumor.

The amount of kidney function remaining after treatment is also important.

Before surgery, doctors may evaluate:

• Serum creatinine

• eGFR

• Urine protein or albumin

• Blood pressure

• Function of the other kidney

• Diabetes status

• Other kidney-disease risk factors

Patients with reduced kidney reserve may require additional planning to protect remaining kidney function.

Can Both Kidneys Be Affected?

Some patients may have tumors affecting both kidneys or may have only one functioning kidney.

In such situations, preserving kidney tissue can become particularly important.

Treatment planning may involve:

• Partial nephrectomy when feasible

• Staged procedures

• Surveillance of selected lesions

• Other kidney-preserving approaches

The treatment strategy should be individualized by the appropriate cancer and kidney specialists.

Ablation Treatment for Renal Cancer

Some selected small kidney tumors may be treated using ablative techniques.

These procedures aim to destroy tumor tissue without removing the entire kidney.

Examples can include techniques that use extreme heat or cold.

Ablation may be considered in selected patients, particularly when surgery carries significant risk.

The suitability of ablation depends on tumor size, location and other medical factors.

Immunotherapy for Renal Cancer

Immunotherapy uses medicines that help the body's immune system recognize and attack cancer cells.

Certain immunotherapy treatments may be used for selected patients with advanced or metastatic renal cancer.

Treatment selection depends on:

• Cancer subtype

• Cancer stage

• Previous treatment

• Overall health

• Other medical conditions

Immunotherapy can have important side effects, including immune-related inflammation affecting different organs.

Patients receiving these medicines require regular monitoring by their oncology team.

Targeted Therapy for Renal Cancer

Targeted therapies are medicines designed to interfere with specific biological pathways involved in cancer growth.

They may be used for selected patients with:

• Advanced renal cancer

• Recurrent renal cancer

• Metastatic renal cell carcinoma

The choice of medicine depends on the type and extent of cancer and the overall treatment plan.

Kidney function, blood pressure and other health factors may need to be monitored during treatment.

Combination Treatment for Advanced Kidney Cancer

Some patients with advanced renal cancer may receive combinations of systemic treatments.

Depending on the clinical situation, treatment may involve combinations of:

• Immunotherapy medicines

• Targeted therapies

• Other oncology treatments

The aim may be to control tumor growth and improve long-term outcomes.

The appropriate treatment regimen should be selected by an experienced oncology team.

What Happens When Renal Cancer Has Spread?

When renal cancer spreads beyond the kidney, it is called advanced or metastatic renal cancer.

Treatment may focus on controlling cancer rather than relying on surgery alone.

Management may include:

• Immunotherapy

• Targeted therapy

• Combination systemic treatment

• Surgery in selected circumstances

• Radiation for specific symptoms or areas of cancer involvement

• Supportive treatment

The treatment plan depends on where cancer has spread and the patient's overall condition.

Is Surgery Always Needed for Renal Cancer?

No.

Surgery is an important treatment for many localized kidney cancers, but it is not appropriate for every patient.

Some patients may undergo surveillance, ablation or systemic treatment instead.

For advanced cancer, systemic therapy may play a central role.

Treatment decisions depend on the individual diagnosis.

Can Renal Cancer Be Treated Without Removing the Entire Kidney?

Yes, in selected cases.

A partial nephrectomy can remove the tumor while preserving part of the kidney.

Some small tumors may also be treated with surveillance or ablation.

However, the possibility of preserving the kidney depends on:

• Tumor size

• Tumor location

• Number of tumors

• Relationship to blood vessels and collecting structures

• Kidney function

• Surgical feasibility

What Is the Role of Radiation Therapy?

Radiation therapy is generally not the main treatment for many localized renal cell cancers.

However, radiation may be used in selected situations, particularly to help manage cancer-related symptoms or treatment of specific areas where cancer has spread.

The use of radiation depends on the patient's cancer type and stage.

Renal Cancer and Chronic Kidney Disease

Patients with kidney cancer may already have reduced kidney function before treatment.

Removing kidney tissue can further reduce kidney filtration in some patients.

Risk factors for chronic kidney disease after kidney cancer treatment may include:

• Reduced kidney function before treatment

• Diabetes

• High blood pressure

• Protein in the urine

• Older age

• Removal of significant kidney tissue

• Problems affecting the remaining kidney

Kidney monitoring before and after cancer treatment is therefore important.

How Can Kidney Function Be Protected During Treatment?

The ability to preserve kidney function depends on the patient's cancer and treatment requirements.

Helpful medical strategies may include:

• Monitoring creatinine and eGFR

• Controlling blood pressure

• Managing diabetes

• Avoiding unnecessary kidney-harming medicines

• Reviewing medicines and treatment doses

• Monitoring hydration according to medical advice

• Checking urine protein when appropriate

• Following recommended follow-up testing

Patients should not take supplements or herbal products marketed for "kidney cleansing" without discussing them with their medical team.

What Tests Are Used to Monitor Renal Cancer?

Follow-up may involve different tests depending on the cancer stage and treatment.

These may include:

Imaging Studies

Imaging can help evaluate:

• Tumor size

• Response to treatment

• Local recurrence

• Spread of cancer

Blood Tests

Doctors may monitor:

• Kidney function

• Liver function

• Blood counts

• Electrolytes

• Other treatment-related markers

Urine Tests

Urine testing may be used to evaluate kidney health or other urinary abnormalities when clinically indicated.

The follow-up schedule is individualized.

Symptoms That May Need Medical Evaluation

Kidney cancer can sometimes produce no symptoms, particularly in its earlier stages.

Possible symptoms may include:

• Blood in urine

• Persistent flank or side pain

• A mass in the side or abdomen

• Unexplained weight loss

• Persistent fatigue

• Unexplained fever

These symptoms can also occur because of other conditions.

Medical evaluation is necessary to determine the cause.

Can Renal Cancer Come Back After Treatment?

Yes, recurrence is possible in some patients.

The risk depends on factors such as:

• Cancer stage

• Tumor characteristics

• Type of renal cancer

• Completeness of treatment

• Other pathological findings

Regular follow-up can help detect recurrence or progression.

Patients should follow the surveillance plan recommended by their treating cancer specialists.

Nutrition During Renal Cancer Treatment

Nutrition needs can vary significantly.

Patients may need support for:

• Maintaining body weight

• Adequate protein and calorie intake

• Managing treatment-related nausea

• Supporting recovery after surgery

Patients with chronic kidney disease may require different dietary advice.

Therefore, dietary plans should be individualized rather than following a generic "cancer diet" or "kidney diet."

Emotional and Psychological Support

A diagnosis of renal cancer can affect both the patient and family emotionally.

People may experience:

• Anxiety

• Fear about cancer progression

• Concerns about surgery

• Worry about kidney failure

• Changes in work and family life

Emotional support and clear communication with the medical team can be an important part of overall cancer care.

When Should Renal Cancer Patients Seek Urgent Medical Attention?

Urgent medical evaluation may be necessary for symptoms such as:

• Heavy or persistent bleeding in urine

• Inability to pass urine

• Severe or worsening pain

• Severe breathlessness

• Chest pain

• Persistent vomiting

• Confusion

• High fever with severe illness

• Sudden major deterioration

Patients receiving cancer treatment should also report significant new symptoms to their treating team.

Frequently Asked Questions About Renal Cancer Treatment

What is the best treatment for renal cancer?

There is no single best treatment for every patient. The appropriate option depends on the cancer type, stage, tumor size and location, kidney function and overall health.

Can renal cancer be cured?

Some localized renal cancers can be treated successfully with surgery or other appropriate treatment. The outlook depends on the cancer type and stage.

Is surgery necessary for kidney cancer?

Surgery is commonly used for many localized kidney cancers, but some patients may be managed with active surveillance, ablation or other treatments depending on their diagnosis.

What is the difference between partial and radical nephrectomy?

Partial nephrectomy removes the tumor while preserving part of the kidney. Radical nephrectomy removes the entire affected kidney.

Can immunotherapy treat renal cancer?

Immunotherapy may be used for selected patients with advanced or metastatic renal cancer and in other specific clinical situations determined by the oncology team.

Can a person live with one kidney after kidney cancer surgery?

Many people can live with one functioning kidney. However, kidney function and risk factors such as high blood pressure and diabetes should be monitored.

Does kidney cancer treatment affect kidney function?

It can. Removing kidney tissue, certain medicines and other medical factors may affect kidney function. Monitoring is especially important for patients with pre-existing kidney disease.

Conclusion

Renal cancer treatment depends on much more than the presence of a tumor in the kidney.

The cancer type, size, stage, location, spread and the patient's remaining kidney function all influence the treatment plan.

Localized cancer may be managed with active surveillance, partial nephrectomy, radical nephrectomy or selected ablative procedures. Advanced renal cancer may require systemic treatment such as immunotherapy, targeted therapy or other oncology-based approaches.

Protecting kidney function is also an important part of treatment planning, especially for patients with chronic kidney disease, diabetes, hypertension or reduced function in the remaining kidney.
