Kidney Cancer - Causes, Symptoms, Risks Factors and More

Kidney cancer or renal carcinoma usually occurs in older people and accounts for about 2 to 3% of cancers in adults, affecting about twice as many men as women. In adults, the most common type of kidney tumor is renal cell carcinoma, which begins in the cells that line the small tubes within your kidneys. Kidney cancer rarely strikes children and young adults; the exceptions are a pediatric kidney cancer called Wilms tumor and some forms of hereditary kidney cancer syndromes, such as von Hippel-Lindau disease.
