Cough, taking Sutent for kidney cancer, kidney removed, spread to both lungs. Cause of this cancer?
Patient: I am taking Sutent for kidney cancer I will have a CT scan soon to see if it has been effective.  I also had a kidney removed and know that it ha spread to both lungs.  I can't seem to ask questions of my doctor in person, just to real, and  reading is eaiser. How did I get this cancer, Inever had any sympotms sxcept for a cough which lead to this discovery. Doctor: Hello!Thank you for the query.It is hard to tell where does the cancer come from. Its a good question. Some kidney cancer are genetic (in few percent). Some are related with smoking, obesity, estrogens and some chemical agents. But so many people smoke and do not have kidney cancer.Generally cancer is caused by single cell mutation which is missed by immune system. Such mutated cell can not be controlled anymore and its only aim is to grow and spread. This process can not be stopped by human body and thats the main problem with cancer.The other thing is that many cancers does not give any symptoms at all.So no one really knows where does the cancer comes from.Hope this will help.Regards.
