Kidney Tumors: Symptoms and Treatments
Kidney tumours are abnormal growths that originate in the kidney tissues. While some kidney tumours are benign and not life-threatening, others can be malignant, leading to a more severe condition known as renal cell carcinoma. Renal cell carcinoma is the most common type of kidney cancer, accounting for about 85% of all cases.
Kidney Tumor Causes
The exact cause of kidney tumours remains elusive, but several risk factors have been identified:
- Genetic predisposition: Certain genetic conditions, such as von Hippel-Lindau disease, increase the risk of developing kidney tumours.
- Lifestyle factors: Smoking, obesity, and hypertension are known contributors.
- Environmental exposures: Prolonged exposure to certain chemicals and substances, such as asbestos and cadmium, may elevate risks.
- Age and gender: Most kidney tumours occur in individuals over the age of 50, with a higher prevalence in males than females.

Kidney tumours are often asymptomatic in their early stages, making them difficult to detect. However, as they grow, they may present several symptoms:
- Hematuria: Blood in the urine is one of the most common signs.
- Flank pain: Persistent pain in the side or lower back.
- Palpable mass: A noticeable lump or mass in the abdomen or side.
- Unexplained weight loss: Significant weight loss without a discernible cause.
- Fatigue and anaemia: Reduced red blood cell count can lead to fatigue and general weakness.
- Fever: Recurring fevers not associated with infections.
The Path to Kidney Tumor Diagnosis
Early detection of kidney tumours can significantly improve prognosis. Diagnosis typically involves a combination of the following methods:
Imaging Techniques
- Ultrasound: A non-invasive method that uses sound waves to produce images of the kidneys.
- CT Scan: This procedure provides detailed cross-sectional images and is often used to assess the size and spread of the tumour.
- MRI: Offers high-resolution images to evaluate tumours in detail, especially in complex cases.
Biopsy
In cases where imaging alone cannot confirm a diagnosis, a biopsy may be performed. A small sample of kidney tissue is extracted and examined under a microscope to determine the presence of cancerous cells.
Blood and Urine Tests
These tests can help identify markers that may indicate the presence of a tumour or assess kidney function.
Treatment Options for Kidney Tumors
Treatment choices depend on the tumour's size, location, stage, and the patient's overall health. Here are the primary kidney tumour treatment options:
Surgical Interventions
- Partial Nephrectomy: The tumour and a small margin of healthy tissue are removed, preserving most of the kidney.
- Radical Nephrectomy: The entire kidney, along with surrounding tissues and possibly nearby lymph nodes, is removed.
Both procedures can be performed using open surgery or minimally invasive techniques, such as laparoscopic or robotic-assisted surgery.
Ablation Techniques
These methods are suitable for patients who cannot undergo surgery:
- Radiofrequency Ablation (RFA): Uses high-energy radio waves to heat and destroy cancer cells.
- Cryoablation: Involves freezing cancer cells to kill them.

Targeted drugs focus on specific pathways or proteins that are essential for tumour growth and survival. These therapies are beneficial for advanced renal cell carcinoma.
Immunotherapy
This treatment leverages the body's immune system to fight cancer cells. Agents such as checkpoint inhibitors have shown promise in treating advanced kidney tumours.
Radiation Therapy
While not commonly used for kidney tumours due to their resistance to radiation, this therapy may be employed in cases where surgery isn't feasible or to relieve symptoms caused by metastasis.
Prognosis and Survival Rates
The prognosis for kidney tumours varies depending on several factors, including the cancer stage at diagnosis and the patient's response to treatment. Early-stage tumours often have a favourable prognosis, with a five-year survival rate exceeding 90%. Conversely, advanced or metastatic kidney tumours have a lower survival rate, highlighting the importance of early detection and intervention.
