What is life expectancy for someone in stage 3 stomach cancer that refuses to take therapy

GOK=God Only Knows: Patient has the right to accept or refuse any therapy. I am just hoping that you are fully informed about the disease, prognosis, treatment options, pros and cons of treatment etc -before you make your decision. Only god knows how long one is going to live. Having said that, when the cancer is not treated-it makes it almost like a stage IV disease- the 5 year survival for stage IV is 7%.

Not known: There is no solid data to identify time to response, however, your physician should be monitoring your scans and psa level routinely, I am not sure what is the stage of your cancer, but as long as there is evidence of response to treatment then you are on the right track.

No answer: It is not possible to predict the survival time in a particular person. The law of averages may suggest a few months, but there are enough exceptions thus making a prediction unreliable.
