 [ Symptoms ] can i eat foods with vitamin k while taking nattokinase  i am taking nattokinase as a supplement for high blood pressure i do not have any bleeding problems or blood clotting problems [ Disease ] i am very very sorry to hear this i can not imagine how you all are feeling it is a tough time you have probably asked the medical team this question about survival and were not satisfied with the response doctors tend to be very vague when talking about survival rates  that is because there is no good definition for what that means it sounds like your husband is asking what his chances are of surviving the chemotherapy unfortunately it is impossible to tell that even doing comparisons with other patients is not useful because every person is baseline health status is different when they enter cancer treatment in general i would guess people who enter cancer treatment as robust individuals probably stand a better chance of getting through the course of treatment than a frail person the other sad truth is this no lung cancer is curable ultimately no one survives lung cancer your husband may understand this and be wondering but how long do i have left  unfortunately there is no crystal ball to predict that it is both a blessing and a frustration that some things are not known by human beings this is one of those things i urge you to cherish every moment you do have left together whether they ultimately number 5 or 5 000 i wish you both peace
