Kidney cancer, or renal cancer, develops in the kidneys, which are responsible for filtering waste from the blood and producing urine. It is one of the 10 most common cancers in both men and women. This post will cover essential information about kidney cancer, including symptoms, risk factors, detection methods, and prevention tips.
What is Kidney Cancer?
Kidney cancer typically begins in the cells lining the kidney’s tubules, which filter blood and produce urine. The most common type is renal cell carcinoma (RCC), which accounts for about 90% of cases. Other types include transitional cell carcinoma and Wilms tumor (most common in children). Kidney cancer is often detected incidentally during imaging for other health concerns, as it may not cause symptoms in its early stages.

Symptoms of Kidney Cancer
Kidney cancer often doesn’t cause symptoms in its early stages, but as it progresses, symptoms may include:
- Blood in the Urine: Visible blood or a change in urine color (pink, red, or brown).
- Lower Back Pain on One Side: Persistent pain in the lower back or side, typically not related to an injury.
- Lump on the Side or Lower Back: A noticeable lump or mass in the abdominal or back area.
- Fatigue and Unexplained Weight Loss: Feeling constantly tired or losing weight without trying.
- Fever that Comes and Goes: Recurrent fevers without a clear cause.
If you experience these symptoms, particularly blood in the urine, consult a healthcare provider for evaluation.
How to Detect Kidney Cancer
Kidney cancer is often found incidentally during imaging tests for unrelated issues. Key detection methods include:
- Urine Test: A urinalysis can reveal blood or abnormal cells, which may indicate kidney cancer or other kidney issues.
- Ultrasound: Ultrasound imaging uses sound waves to create images of the kidneys, helping detect tumors.
- CT or MRI Scan: These imaging tests provide detailed images and can help detect kidney tumors and assess if cancer has spread.
- Biopsy: In cases where imaging shows a suspicious mass, a biopsy may be performed to confirm the presence of cancer cells.
Risk Factors for Kidney Cancer
Certain factors can increase the risk of kidney cancer:
- Smoking: Smoking doubles the risk, as harmful chemicals enter the bloodstream and are processed by the kidneys.
- Obesity: Excess weight can cause hormonal changes that raise kidney cancer risk.
- High Blood Pressure: Hypertension has been linked to an increased risk of kidney cancer.
- Family History: Those with close relatives who had kidney cancer are at a higher risk.
- Long-Term Dialysis: Patients on long-term dialysis due to kidney failure have a higher risk of developing kidney cancer.
Prevention Tips for Kidney Cancer
While not all kidney cancer cases can be prevented, specific lifestyle choices can reduce risk:
- Quit Smoking: Avoiding or quitting smoking is one of the most effective ways to lower kidney cancer risk.
- Maintain a Healthy Weight: A balanced diet and regular exercise help reduce risk.
- Control Blood Pressure: Managing high blood pressure through diet, exercise, and medications can reduce kidney cancer risk.
- Stay Hydrated: Drinking plenty of water helps keep the kidneys functioning well, which may help lower cancer risk.
Conclusion
Kidney cancer is often silent in its early stages, making regular check-ups and attention to symptoms like blood in the urine essential. Recognizing risk factors and taking preventive steps, such as avoiding smoking and maintaining a healthy lifestyle, can reduce your risk. If you notice any symptoms, consult a healthcare provider promptly.
Proactive health management and early detection can make a significant difference—stay informed, stay healthy.
