It should come as no surprise that smoking causes any kind of cancer, even kidney cancer. WebMD writes that any person who smokes cigarettes is twice as likely to develop kidney cancer as someone who doesn’t. The source also notes that cigars might also contribute to an increased risk.
The American Cancer Society expands on this topic by explaining that smoking increases the risk of developing renal cell carcinoma (RCC), which is the most common type of kidney cancer. “The increased risk seems to be related to how much you smoke. The risk drops if you stop smoking, but it takes many years to get to the risk level of someone who never smoked,” writes the source.
