Is kidney transplantation a viable option for people with kidney cancer?

Yes. Small cancers found incidentally have little impact on the ability to get a kidney transplant. Larger tumors or those that have spread away from the kidney will require the patient to wait a period of time (usually 3-5 years) to make sure that the cancer is "cured" before they are allowed to receive a kidney transplant.
Not right away. One needs to be cancer free (2-5 years) before he or she can safely transplanted. A lot depends on the type of cancer and the extent of the disease (stage).
It could be. If a patient with a localized kidney cancer (confined to the kidney) is cured after the cancer is removed, but in the process has lost their kidney function and needs dialysis, a transplant could be done. This generally requires a 1-2 year interval of time after the cancer is removed to be sure it has not returned. It will also depend on the type and the extent (stage) of the kidney cancer.

Is it possible to get kidney cancer one year after kidney transplant? At stage 3 is it curable?

I gues it is possibl. This is a bit unusual. Your transplant doctor can advise you better. Stage 3 cancer does have a finite cure rate after adequate surgical treatment but it takes several years of follow up to be sure that you are trouble free or not. Read more...
Yes. Very low liklihood , but possible! possible to cure also with combination surgery, chemo radiation as appropriate from pathology. Read more...

If a cancerous kidney was transplanted to a different person, would that person then develop kidney cancer?

Yes. If a kidney that is transplanted has cancer in it, then the recepient will continue to have the same cancer and it will continue to grow. If not treated, it will metastasize and spread. Many tests are performed prior to transplantation to prevent this from occuring. Read more...
Most likely. Yes, especially since after kidney transplant patients require medications to suppress the immune system in order to prevent rejection of the transplanted kidney. Cancer tends to grow faster when the immune system has been suppressed. That is why both transplant donors and recipients are very carefully screened for diseases like cancer and infections.
