Lung cancer is a global chronic disease that endangers public health. So far, the five-year survival rate of lung cancer is still not satisfactory. In the long-term battle with lung cancer disease, patients not only have to suffer from physical discomfort, but also have to suffer from the long-term survival pressure of uncertainty whether and how long they can survive, which is known as psychological troubles. The physical discomfort, such as pain, cough, difficulty in breathing, fatigue, etc., can attract a lot of attention from family members, friends and relatives, and thus can be promptly dealt with by professional lung cancer doctors. The latter distress, on the other hand, often becomes a mental health problem of patients and is not paid attention to and valued by all parties. In fact, psychological troubles are a very common emotional response among all cancer patients. During the whole process of lung cancer patients’ struggle with the disease from diagnosis, treatment, recurrence, palliative residual to the end of life, some adverse emotions, such as sadness, anxiety, fear, worry, poor state of mind, etc., are bound to arise. The existence of these negative emotions will affect the function of patients’ own immune surveillance system and lead to the decrease of their own ability to resist cancer cells; on the other hand, it will make patients’ life behavior and quality of life decrease. Therefore, patients are reluctant to communicate with friends and relatives, unwilling to participate in social activities and confine themselves to their homes as much as possible. Patients with lung cancer have various forms of psychological troubles, such as sadness, tears, anxiety, depression, worry, fear, fear, depression, lack of concentration, guilt, low sex drive, easy to get angry, no interest in activities, reduced working ability, insomnia and dreaminess, and so on. Therefore, if a lung cancer patient shows the above-mentioned manifestations, as a family member, as a relative or a friend, as a medical team, we must pay attention to them, actively guide the patient to free himself from negative psychological worries, fully understand the above-mentioned manifestations of the patient, patiently and meticulously guide him, considerately care for him, let him realize that he is not fighting alone, but there are doctors, nurses, family members and society as his strong support. Through the efforts of the patient and all of us, there will definitely be a good result; if he doesn’t try, doesn’t make efforts, is immersed in worries all day long, doesn’t actively face them and doesn’t actively cooperate with the treatment, it is equal to giving in and giving up. You should believe that you can live a wonderful life even if you have lung cancer, and you can enjoy the nourishment of sunshine and rain. Live one day, be happy; live one day, be happy!
