What Is Renal Cell Carcinoma – Oncocytoma?
Renal cell carcinoma – oncocytoma is a benign kidney tumor characterized by its rich content of mitochondria, giving the cells a distinctive granular appearance. Although oncocytomas are non-cancerous and typically do not spread to other parts of the body, their diagnosis is important as they can closely resemble certain types of renal cell carcinoma (RCC) under imaging studies. Oncocytomas account for a significant percentage of all renal tumors and are often discovered incidentally during imaging tests for other conditions.
Renal oncocytomas usually do not cause symptoms and are often found incidentally during imaging studies for unrelated health issues. In some cases, if the tumor grows large enough, it may cause:
- A palpable mass in the abdomen or side.
- Blood in the urine (hematuria).
- Pain or discomfort in the side, back, or abdomen.
- Unintentional weight loss (rare).
Disease Aetiology (Causes)
The exact cause of renal oncocytoma is not well understood. As with many tumors, genetic and environmental factors may play a role, but specific risk factors for oncocytoma have not been clearly identified.
The diagnosis of renal oncocytoma often involves:
- Imaging tests, such as ultrasound, computed tomography (CT) scans, and magnetic resonance imaging (MRI), to visualize the kidney and the tumor.
- Biopsy, in which a sample of the tumor is taken and examined under a microscope, can help differentiate oncocytoma from malignant kidney tumors.
- Blood and urine tests to assess kidney function and look for signs of other kidney diseases.
Because renal oncocytomas are benign, treatment may not always be necessary. When intervention is required, options include:
- Active surveillance, especially for smaller tumors, involves regular monitoring with imaging tests.
- Surgery, such as partial nephrectomy, to remove the tumor while preserving as much kidney function as possible. Complete nephrectomy, removal of the entire kidney, is less common and typically reserved for larger or more complex tumors.
- Ablative therapies, such as radiofrequency ablation or cryoablation, are minimally invasive options for some patients.
What support can we give for the Renal Cell Carcinoma?
Renal Cell Carcinoma is a rare cancer, meaning it is not as well-known as other forms of cancer. Without a Ribbon is an Australian organisation that provides support for individuals who suffer from rare cancers. So, we provide a designated platform for Warriors to obtain information specific to their Rare Cancer. We also provide annual opportunities for our Warriors to meet and learn from each other. If you suffer from rare cancer such as Renal Cell Carcinoma, we can help and support you through your journey thanks to the generous donations we receive.
