Kidney cancer most often spreads to lungs and bones, but it can also spread to brain, liver, and other organs. As it has no symptoms early on, it can spread before you even know you have it. Smoking tobacco doubles the risk of developing kidney cancer. Prevention of metastatic kidney cancer can be done by quitting smoking, maintaining a healthy body weight & eating a diet high in fruits & vegetables & low in fat. If cancer has not spread far, surgery may be a cure. If it has spread to other organs, then treatment like targeted therapy and Immunotherapy will be recommended.
