Thanks for posting the query. Considering the Lung cancer
to be the primary & metastasis to kidney
, this will be a stage 4 lung cancer.
That said, the median stage 4 non-small cell lung cancer life expectancy (the time at which 50% of patients are alive and 50% have passed away) is only around 8 months. The 5-year survival rate
, that is the percent of people who are expected to be alive 5 years after a diagnosis of stage 4 lung cancer is sadly less than 10%.
