Blood in the urine
Pink, red or cola-coloured urine, or blood detected on testing, needs medical assessment. It can have causes other than cancer.

Understanding Kidney Cancer
Clear, practical information to help you recognise possible warning signs, understand tests and discuss kidney cancer treatment options with your care team.
This guide supports informed conversations with your doctor. It does not replace an individual medical assessment.
How to use this guide
Use these sections to understand possible next steps, prepare questions and discuss your options with your doctor.
Learn the warning signs
Understand symptoms and when they need assessment.
Understand diagnosis
Learn about urine tests, imaging and biopsy when indicated.
Explore treatment options
Compare surgery, monitoring and other treatments.
Prepare for consultation
Know which reports and questions to bring.
What to look for
Possible symptoms of kidney cancer
Early kidney cancer may cause no symptoms and may be found incidentally on imaging. These symptoms can have causes other than cancer, but persistent or visible changes should be assessed.
Persistent side or back pain
Ongoing pain below the ribs or in the flank should be assessed, particularly if it is unexplained or persistent.
A lump near the kidney area
A mass in the abdomen or flank is not a common early sign, but needs prompt clinical evaluation.
Unexplained weight loss
Unintentional weight loss or reduced appetite can have many causes and should be reviewed if persistent.
Persistent fatigue or fever
Ongoing tiredness, fever or feeling generally unwell can occur for many reasons and should not be self-diagnosed.
Persistent scrotal vein swelling
A new persistent varicocele, particularly on the right, or otherwise unexplained leg swelling should be assessed. These findings are uncommon and have many other causes.
When should you seek medical advice?
Visible blood in the urine should be assessed promptly, even if painless or occurring only once. Seek urgent care if you have heavy bleeding, severe pain, fever with flank pain, or difficulty passing urine.
Understanding risk
Factors associated with kidney cancer
Risk factors change the likelihood of disease but do not determine an individual outcome. Some people develop kidney cancer without a known risk factor.
Smoking
Smoking is an established risk factor. Stopping smoking benefits overall health and may reduce future risk.
Excess body weight
Higher body weight is associated with increased risk of renal cell cancer in population studies.
High blood pressure
High blood pressure is associated with kidney cancer risk. It is important to manage it for overall health.
Family history or inherited conditions
Some inherited conditions and a strong family history can increase risk; most kidney cancers are not inherited.
Long-term dialysis and certain hereditary conditions are additional risk factors. If cancer develops at a young age, affects both kidneys, or runs in the family, ask whether genetic counselling is appropriate.
Understanding the diagnosis
What are the main types of kidney cancer?
Most adult kidney cancers are renal cell carcinomas. A pathology report may describe a subtype, which can help guide care.
Clear cell renal cell carcinoma
The most common type of renal cell cancer.
Papillary renal cell carcinoma
A distinct subtype with different biological features.
Chromophobe renal cell carcinoma
A less common renal cell cancer subtype.
A tumour arising in the renal pelvis may instead be a urothelial cancer, which is evaluated and treated differently. Not every kidney mass is cancerous.
Getting a clear diagnosis
How kidney cancer is diagnosed
The evaluation depends on imaging findings, kidney function, symptoms and whether the result will change management.
1
Clinical assessment
Your clinician reviews symptoms, medical history, medicines and examination findings.
2
Urine and blood tests
Tests may look for blood in urine, assess kidney function and help evaluate other possible causes.
3
Imaging tests
Ultrasound, contrast CT or MRI may be used to assess the kidney mass and whether it has spread.
4
Biopsy when appropriate
A biopsy is not required before every kidney operation. It may be recommended when the result will help guide management.
Why kidney function matters
Blood tests and imaging help clinicians understand kidney function and anatomy before choosing treatment. Preserving functioning kidney tissue is an important consideration when it can be done safely.
Treatment decisions
Kidney cancer treatment options
Treatment is individualised according to tumour size, location, stage, kidney function, overall health and personal preferences.
Partial or radical nephrectomy
Surgery may remove only the tumour and a rim of healthy tissue, or the whole kidney, depending on tumour features and kidney function.
Active surveillance or ablation
For selected small masses or people with specific health considerations, careful monitoring or an ablative procedure may be appropriate.
Targeted therapy and immunotherapy
Some advanced kidney cancers are treated with systemic medicines selected according to the disease and the person's overall condition.
Radiotherapy and symptom control
Radiotherapy is not the usual primary treatment for most localised kidney cancers, but may help in selected cases, including symptom relief.
Can the kidney be preserved?
For suitable localised tumours, partial nephrectomy may remove the tumour while preserving more healthy kidney tissue. The choice depends on tumour anatomy, cancer risk, kidney function and surgical feasibility.
Does every kidney mass need treatment immediately?
Not always. Active surveillance may be appropriate for selected small masses, particularly when immediate treatment risks outweigh likely benefits. This requires a planned follow-up strategy with the treating team.
What happens next
Your kidney cancer treatment journey
This is a general overview. Your own plan and timeline may differ depending on diagnosis, stage and recommended treatment.
STEP 1
First consultation
Discuss symptoms, medical history, kidney function and any previous scan reports.
STEP 2
Characterise the kidney mass
Review imaging to understand size, location and involvement of nearby structures.
STEP 3
Clarify the diagnosis
Determine whether biopsy or additional tests are needed before deciding on treatment.
STEP 4
Compare options
Discuss surveillance, ablation, surgery or systemic treatment as appropriate.
STEP 5
Plan treatment and recovery
Review the expected course, kidney function considerations and recovery needs.
STEP 6
Follow-up
Attend visits and tests to monitor recovery, kidney function and recurrence risk.
Preparing for your consultation
Bringing your records can help make the discussion more focused.
- Previous CT/MRI images and reports, ultrasound and pathology if available
- Recent kidney function blood tests and urine reports
- A list of medicines, supplements and allergies
- Relevant personal and family medical history
- Your main concerns and questions
Surgical oncology consultation
Discuss your kidney cancer treatment options
Dr. Abhishek Kumar Verma (MCh), Surgical Oncologist, can review available reports, explain the role of surgery and discuss how surgical decisions fit into the wider treatment plan.
Recommendations require review of your individual diagnosis and clinical findings.
Common questions
Kidney cancer FAQs
General answers to questions patients often raise during consultation.
Q.Does blood in the urine always mean kidney cancer?
No. Urinary infection, stones and other conditions can also cause blood in urine. It should still be assessed, even if it occurs only once or is painless.
Q.Does every kidney mass need surgery?
No. Management depends on size and appearance of the mass, its growth, kidney function, overall health and patient preferences. Options can include surveillance, ablation or surgery.
Q.Will the whole kidney always be removed?
No. For suitable tumours, partial nephrectomy removes the tumour while preserving more functioning kidney tissue. The safest operation depends on the tumour and individual circumstances.
Q.Is a biopsy always required before kidney cancer surgery?
No. A biopsy is useful in selected situations, particularly when the result may change management. The treating team decides whether it is needed.
Q.Can I seek a second opinion?
Yes. Bring CT/MRI images and reports, blood and urine results, pathology if available, and your medication list so the options can be reviewed.
