Kidney cancer is a malignant tumour developed from the kidney cells. Malignant kidney tumours account for 2-5% of malignant cancers in adults. Men are affected twice as often as women. The cause of kidney cancer is unknown, however, some genetic factors and damages of the kidney cell DNA caused by e.g. cigarette smoking, mutagens or environmental factors are taken into consideration. It is usually diagnosed in people over the age of 45, however, recently, the reduction of the age limit of people who are diagnosed with kidney cancer have been observed, which is affected by the growth of influence of the environmental carcinogenic factors, as well as the spread and constant improvement of diagnosing possibilities.
