Many people assume pain near the kidneys is caused by kidney stones, but in some cases it can be a sign of kidney cancer. While kidney cancer is less common than stones, recognizing the warning signs early is important.
1. Persistent Pain in the Side or Lower Back
Kidney cancer may cause a dull, ongoing pain in the side, back, or below the ribs that does not go away. Stone pain is often severe and comes in waves.
2. Blood in the Urine
One of the most common signs of kidney cancer is blood in the urine. It may appear pink, red, or brown, or be detected only through testing.
3. Unexplained Weight Loss
Losing weight without dieting or increasing physical activity can be a warning sign of several cancers, including kidney cancer.
4. Constant Fatigue
Feeling unusually tired or weak for weeks despite adequate rest may indicate an underlying health problem.
5. Fever Without Infection
Repeated episodes of fever that are not linked to a cold, flu, or other infection should be evaluated by a doctor.
6. A Lump or Swelling
In some cases, a mass or swelling may be felt in the side, abdomen, or lower back area.
7. Loss of Appetite
A persistent decrease in appetite can occur as kidney cancer progresses.
8. When to Seek Medical Advice
If kidney-area pain lasts for several weeks, is accompanied by blood in the urine, unexplained weight loss, fatigue, or fever, consult a healthcare professional promptly.
Conclusion
Not every pain near the kidneys is caused by a stone. While kidney stones are common, persistent symptoms such as blood in the urine, ongoing pain, unexplained weight loss, and fatigue should never be ignored. Early diagnosis of kidney cancer can significantly improve treatment outcomes.
