I would suggest editing this question to include better tags. Your only tag is “cancer and survival.” It is unlikely this will be routed to anyone who can help because “cancer and survival” is not a tag that has been used before, and it is not listed in anyone’s areas of expertise. You should probably repost your question with the tags, “health, medicine, medical, doctor, doctors, cancer, probability, survival, prognosis, expectancy, eating, drinking, stomach, throat.”
