Renal cancer, also known as renal cell carcinoma or kidney cancer, is a type of cancer that develops in the cells of the kidney. Young children are more likely to have a different type of kidney cancer called a Wilms tumor. Renal cancer typically occurs in adults over 50 years, and is twice as likely to affect men than women.
In the early stages, patients with renal cancer often show no signs or symptoms. More advanced renal cancer may cause the one or more of the following:
- Blood in the urine
- High blood pressure
- Weight loss
The exact underlying cause or causes of renal cancer are unknown. However, suggested factors that may increase the risk of renal cancer include age, smoking, high blood pressure, obesity, genetic predisposition, exposure to certain chemicals, and long-term dialysis due to chronic kidney failure. Treatment for renal cancer varies based on a number of factors, such as the location and stage of the cancer, as well as a patient’s overall general health.
Treatment options for renal cancer may include one or more of the following:
- Surgical removal (nephrectomy)
- Targeted therapy
