Kidney cancer develops without apparent symptoms in its early phases, thus making prompt treatment very challenging. Globally, kidney cancer accounts for 2% of total cancer diagnoses, with 208,500 new cases every year. Medical tests for unrelated purposes detect 80% of kidney cancer cases, thus demonstrating why preemptive health check-ups matter. The blog highlights why specific kidney cancer symptoms need immediate attention.
Synopsis
Kidney Cancer: An Overview
Our kidneys are two bean-shaped organs, one on each side of the spine just below the rib cage. Their primary function is to filter waste products from the blood and produce urine. Sometimes, genetic mutations cause healthy cells within the kidneys to transform and grow uncontrollably, leading to the development of kidney cancer (also called Renal cancer). There are various types of kidney cancer, with renal cell carcinoma (RCC) being the most common. It originates in the lining of the tiny tubules within the kidneys that filter our blood.
While the exact causes of these mutations are not always clear, risk factors like smoking, obesity, high blood pressure, and family history can increase the likelihood.
Silent Kidney Cancer Symptoms
Kidney cancer often develops without early symptoms, making it difficult to detect in its initial stages. >60% are incidentally detected during regular health checks. However, some symptoms may indicate its presence.
Below are some silent symptoms of kidney cancer you shouldn't ignore:
-
Blood in urine (haematuria): Even a tiny amount can be a warning sign.
-
Persistent flank or lower back pain: Discomfort on one side of the body between the upper abdomen and back may occur.
-
Unexplained weight loss: Losing weight without changes in diet or exercise can be concerning.
-
Fatigue: Constant tiredness not relieved by rest.
-
Fever without infection: Recurrent fevers without a known cause.
-
Anaemia: Low red blood cell count leading to paleness and weakness.
-
Varicocele: Non-reducing isolated Left Varicocele (Scrotal discomfort/Mild Pain)
Recognising when to consult a doctor is crucial for the early detection of kidney cancer, as it often presents with subtle symptoms. If you experience the above symptoms, consult an expert urologist promptly for evaluation and effective treatment of kidney cancer.
Why Early Detection of Kidney Cancer is Important?
Early detection of kidney cancer significantly improves treatment outcomes and survival rates. The five-year survival rate ranges from 70% to 90% when diagnosed at stage I. However, this rate drops to about 8-10% for stage IV diagnoses.
A Basic Ultrasound scan of the abdomen would detect most of the Kidney cancers. Early-stage identification allows for less invasive treatments, reducing recovery time and potential complications.
Robotic Partial nephrectomy has revolutionized the management of Kidney cancer, by which the tumor can be completely resected, leaving behind the healthy functioning kidney. It is associated with small incisions, less pain, faster recovery and superior oncological outcomes.

Who is at Risk?
Understanding the risk factors for kidney cancer is crucial for early detection and prevention. Below are some major risk factors of kidney cancer:
-
Smoking: Smokers have a higher risk of developing kidney cancer compared to non-smokers.
-
Obesity: Excess body weight increases the likelihood of kidney cancer.
-
High blood pressure (hypertension): Elevated blood pressure is associated with a greater risk of kidney cancer.
-
Family history: Having immediate relatives with kidney cancer can double to quadruple your risk.
-
Occupational exposures: Exposure to chemicals like asbestos, cadmium, and certain solvents may increase the risk.
-
Long-term dialysis: Extended dialysis treatment for kidney failure elevates the risk of developing kidney cancer.
Diagnosis and Next Steps
Accurate kidney cancer diagnosis is vital for determining appropriate treatment strategies and improving patient outcomes.
-
Medical Imaging: Techniques like Ultrasound, CT scans, and MRI detect and assess kidney masses. CT scans, in particular, are effective in diagnosing and staging kidney cancer.
-
Laboratory Tests: Blood and urine analyses evaluate kidney function and detect abnormalities.
Following a confirmed diagnosis, treatment options may include surgery, targeted therapies, immunotherapy, or participation in clinical trials exploring innovative treatments. Early detection and a comprehensive diagnostic approach are crucial for effective management of kidney cancer.
Conclusion
Early detection of kidney cancer improves treatment success and survival rate, having the potential for a complete cure. Conventionally, most cases of kidney cancer were diagnosed late due to early symptoms being generic or nonspecific. With the advent of regular health check-ups, early diagnosis is being made, leading to better outcomes and longer survival. Thus, it’s important to watch for any unusual symptoms and opt for regular health screenings to detect and manage these diseases early. Remember, taking proactive steps towards health can lead to early diagnosis, better treatment options, and improved outcomes for kidney cancer patients.

FAQ's
Yes, some genetic conditions like Von Hippel-Lindau (VHL) disease increase the risk. A family history of kidney cancer may also raise your chances.
Most cases of kidney cancer affect only one kidney. However, both kidneys may also be involved in rare genetic conditions or advanced stages.
Yes, in advanced stages, kidney cancer can spread to the lungs, bones, liver, or brain. In such situations, the treatment options become limited and more challenging.
Kidney cancer is more common in men than women (M:F = 3:2). Studies suggest lifestyle factors like smoking and hypertension contribute to this difference.
Maintaining a healthy weight, avoiding smoking and Tobacco usage, and controlling blood pressure may lower the risk of developing kidney cancer.
