A: As long as lung cancer is treated properly, long-term survival or even cure is possible. We suggest that, with the consent of patients’ families, patients should be given an open and honest account of their condition and informed that lung cancer is curable. Most patients, after a short period of panic, can quickly calm down and face it positively, pushing the treatment in a good direction. As for those patients who are kept in the dark, it is difficult to establish trust between doctors and patients, and patients either do not cooperate with the treatment or speculate about their condition indiscriminately and have serious psychological problems, which is ultimately detrimental to the treatment.
