Overview
Kidney cancer is a serious condition that often develops quietly, with many people showing no symptoms in the early stages. The kidneys help filter waste and maintain fluid balance in the body, so their proper functioning is important for overall health. The challenge is that Kidney Cancer Symptoms can look similar to those of more common problems, such as urinary tract infections or kidney stones, which can delay diagnosis.
Understanding the possible warning signs and the main Kidney Cancer Causes can make a real difference in detecting the disease early and starting the proper treatment.
At Venkateshwar Hospital, our team of experienced oncologists and urologists offers comprehensive care for kidney cancer. From early detection and accurate diagnostic tests to advanced surgical and medical treatment options, patients benefit from a personalised approach designed to achieve the best possible outcomes. Our specialists guide you every step of the way, providing reassurance and support throughout diagnosis, treatment, and follow-up care.
What is Kidney Cancer?
Kidney cancer develops when normal cells in the kidneys undergo changes in their DNA and begin growing uncontrollably. The most common type is renal cell carcinoma (RCC), which accounts for roughly 85–90% of all cases. Other less common forms include transitional cell carcinoma of the renal pelvis, Wilms’ tumour, which is primarily seen in children, and renal sarcoma.
Globally, kidney cancer accounts for approximately 2–3% of all cancers. Its increasing detection is due primarily to incidental findings during imaging scans performed for other reasons. Lifestyle factors such as smoking, obesity, and high blood pressure also play a role in raising the risk. Early detection is crucial, as cancers identified before they spread to other organs are generally easier to treat and are associated with better outcomes.
Kidney Cancer Symptoms
Early-stage kidney cancer often shows no symptoms and is frequently discovered incidentally during imaging for unrelated conditions. When symptoms do appear, they can include blood in the urine (haematuria), persistent pain in the side or lower back, or a palpable lump in the abdomen.
Early Symptoms
- Blood in the urine (haematuria), which may be visible or microscopic
- A lump or mass felt in the kidney area (though uncommon in early stages)
It is important to note that many patients with early kidney cancer do not experience noticeable symptoms.
Advanced Symptoms
As the disease progresses, more evident signs may develop, including:
- Persistent pain in the lower back or side
- Unexplained weight loss and loss of appetite
- Constant fatigue or low energy
- Recurrent fevers without a clear cause
- Anaemia-related weakness
- Swelling in the ankles or legs, which can result from tumour spread into veins or lymphatic obstruction, rather than kidney failure itself.
Why Symptoms Are Overlooked?
The difficulty with recognising Kidney Cancer Symptoms is that they often resemble everyday health issues. For example, blood in urine may be mistaken for infection, while back pain may be attributed to muscle strain. This makes medical evaluation essential, particularly for those with known risk factors.
Kidney Cancer Causes
Kidney cancer develops due to a combination of genetic predispositions, environmental exposures, and lifestyle habits. Understanding these Kidney Cancer Causes helps identify those at higher risk.
Genetic Factors
Inherited conditions, such as Von Hippel-Lindau disease or a strong family history of kidney cancer, significantly increase the risk. Although hereditary cases are less common, regular monitoring is essential for individuals with such conditions.
Lifestyle and Environmental Factors
- Smoking nearly doubles the risk of developing kidney cancer.
- Obesity alters hormone activity, potentially encouraging tumour growth.
- Long-term high blood pressure is associated with an increased risk.
- Exposure to harmful chemicals, such as cadmium and asbestos, can play a role.
Medical Conditions
Certain health conditions also contribute to a higher risk:
- Polycystic kidney disease
- Long-term dialysis treatment
- Chronic kidney disease
When to Seek Medical Help?
Symptoms such as visible blood in the urine, persistent flank pain, or unexplained weight loss should not be ignored. While not every case is cancer, only a specialist can rule out serious causes. Since no standard screening programme exists for the general population, vigilance is particularly important in high-risk groups.
At Venkateshwar Hospitals, our specialists use advanced diagnostic tools to evaluate symptoms and create a personalised care pathway.
Diagnosis of Kidney Cancer
A correct diagnosis is essential for planning effective treatment. At Venkateshwar Hospitals, specialists use a combination of tests to confirm kidney cancer, identify its type, and determine its stage.
Imaging Tests
- Ultrasound: Often the first step, it can detect masses or irregularities in the kidney.
- CT Scan (Computed Tomography): Provides detailed images to assess tumour size, location, and any local spread.
- MRI (Magnetic Resonance Imaging): Used in certain cases for clearer images of soft tissues, blood vessels, or complex tumours.
Blood and Urine Tests
- Blood tests check kidney function and general health.
- Urine tests can detect blood or other signs of kidney problems.
Biopsy
- Occasionally, a small tissue sample is taken to confirm the type of kidney cancer and provide information for treatment decisions.
Additional Assessments
- If needed, chest imaging or bone scans are performed to check if the cancer has spread.
- Staging helps determine whether the cancer is confined to the kidney or has reached other organs or lymph nodes.
These investigations, taken together, provide a comprehensive picture of the disease, enabling doctors to determine the most suitable course of treatment.
Treatment Options for Kidney Cancer
Treatment depends on the cancer’s stage, type, and the patient’s overall health.
- Surgery: Partial nephrectomy (removing the tumour while preserving kidney tissue) or radical nephrectomy (removing the entire kidney) remains the most common treatment.
- Targeted Therapy: Drugs that block specific pathways cancer cells use to grow.
- Immunotherapy: Boosts the body’s immune system to fight cancer.
- Radiation Therapy: Not typically used as a curative option since kidney cancer is relatively resistant, but it may help relieve pain from bone or brain metastases.
At Venkateshwar Hospitals, patients are treated by a multidisciplinary team, ensuring every aspect of care is tailored to individual needs.
Prevention and Lifestyle Tips of Kidney Cancer
While not all cases can be prevented, specific lifestyle changes can lower risk:
- Quit smoking
- Maintain a healthy weight.
- Control high blood pressure
- Stay physically active and follow a balanced diet.
- Seek regular medical advice if you have hereditary risk factors or a history of chronic kidney disease.

Frequently Asked Questions
1. What are the first signs of kidney cancer?
Many early-stage kidney cancers do not cause noticeable symptoms and are found incidentally during imaging tests. When symptoms do appear, Kidney Cancer Symptoms may include blood in the urine (haematuria), a lump or swelling in the side or lower back, persistent pain in the flank, or unexplained fatigue.
2. Can kidney cancer be detected early?
Yes, but early detection usually happens by chance during imaging for other conditions. Unlike some cancers, there is no standard routine screening for the general population. High-risk individuals may benefit from monitoring or regular check-ups.
3. What are the main Kidney Cancer Causes?
Kidney Cancer Causes involve a combination of genetic, lifestyle, and medical factors. Key risk factors include inherited genetic syndromes, smoking, obesity, high blood pressure, and certain chronic kidney conditions or long-term dialysis.
4. Does smoking increase the risk of kidney cancer?
Yes. Smoking significantly raises the risk of developing kidney cancer, nearly doubling it compared to non-smokers.
5. Can kidney cancer be cured completely?
Early-stage kidney cancers that are treated surgically have high survival rates. However, even after treatment, there is a possibility of recurrence, so ongoing follow-up is important.
6. At what age is kidney cancer most common?
Kidney cancer most often affects adults over the age of 50, though it can occur at younger ages in rare cases or in those with hereditary syndromes.
7. How is kidney cancer diagnosed?
Diagnosis typically involves a combination of imaging tests (such as ultrasound, CT, or MRI), blood and urine tests to assess kidney function, and, when necessary, a biopsy to confirm the type and stage of the cancer.
8. Is kidney cancer hereditary?
A small proportion of cases are linked to inherited genetic syndromes such as Von Hippel-Lindau disease. Most kidney cancers, however, occur sporadically without a family history.
9. When should I visit a doctor for kidney-related symptoms?
Medical advice should be sought if you notice Kidney Cancer Symptoms such as blood in urine, persistent back or flank pain, unexplained weight loss, or swelling in the legs. Early evaluation enhances the likelihood of timely treatment and improved outcomes.
