Cause of Kidney Cancer
Researchers have not yet identified any specific kidney cancer causes; however, they have learned that there are certain risk factors for the disease. While such a risk factor may not cause the disease, it does increase the chances of developing it. Examples of risk factors for kidney cancer include smoking, being obese, and having high blood pressure.
No one knows the exact cause of kidney cancer, and doctors can seldom explain why one person will get kidney cancer and another person will not. However, it is clear that this disease is not contagious -- no one can "catch" kidney cancer from another person. Kidney cancer research has shown that people with certain risk factors are more likely than others to develop the disease. A risk factor is anything that increases a person's chances of developing a disease. While not a cause of kidney cancer, a risk factor for the disease may increase a person's chances of getting the disease.
This article uses the term "kidney cancer" to refer to renal cell carcinoma (also known as renal cell cancer), the most common type of kidney cancer.
