Signs of kidney cancer include:
- Blood in urine
- Pain in the flank (side of the body)
- High blood pressure
These symptoms do not absolutely indicate that kidney cancer is present and these signs may occur in the face of other noncancerous conditions. It is also important to note that many patients who develop kidney cancer experience none of these symptoms and their tumors are found incidentally on imaging studies.
Causes and Risk Factors
There is no known absolute cause for the development of kidney cancer. The cancer can occur at any age but most occur after the age of 50. Twice as many men as women develop kidney cancer.
The risk factors for kidney cancer may include:
- Family history of kidney cancer
- High-fat diet
- Exposure to asbestos, solvents and cadmium
