When a patient is diagnosed with a tumor, should he be told the truth, or should he be kept in the dark with well-intentioned lies? Many doctors and family members of tumor patients often feel dilemma about this. Because in front of the cruel truth, some people’s fighting spirit will be aroused, and they will fight with the tumor tenaciously, and even create the “miracle” of anti-tumor. Such cases are not uncommon in clinical practice. When Ms. Zhou was diagnosed with lung cancer, it was already in the middle to late stage, and the tumor was already very big and had metastasis and spread, so according to reason, she could only live for about half a year at most. However, at that time, Ms. Zhou’s daughter was less than one year old. At first, Ms. Zhou was very negative, thinking that it would be better to give up since her condition was already so bad. But then the doctor’s words changed her mind: “Your daughter is still so young, what would she do without her mother?” The doctor’s words gave Ms. Zhou a reason to fight against cancer, and her “daughter” became her motivation to live. Since then, Ms. Zhou has been very cooperative with the treatment, and has followed the treatment plan formulated by the doctor for radiotherapy, chemotherapy, surgery, etc., and has started a battle with the “tumor”. As a result, the patient, who could only have lived for half a year at most according to the norm, lived for another 10 years. At the time of her death, the child who was still waiting to be fed was already in elementary school. London King’s University once made a breast tumor patients as the object of observation of the study, reported that the survival rate of patients with breast tumors for statistical purposes, the fighting spirit of tenacious patients can live through 10 years as high as 80%; calmly accept the patient’s 10-year survival rate of 33%; and hold the attitude of despair in patients with a 10-year survival rate of only 20%. Research shows that those who can accept treatment with a positive attitude and adjust their lifestyles after developing a tumor, the tumor cells will become timid and retreat. On the contrary, even the best drugs in the clinic do little for patients who are emotionally disillusioned and disillusioned. Most patients prefer to know the truth. There has long been a difference of opinion about whether to be truthful about a patient’s diagnosis. Studies have shown that more than 80% of patients actually prefer to know about their condition. Therefore, once a tumor is diagnosed, doctors should inform patients and their families along with their condition and treatment plan. This is a very important point. If the patient is told one diagnosis and the family is told another diagnosis, it will lead to extreme mistrust of the doctor’s treatment and the family’s words and deeds, thus anxiety and misunderstanding will occur, which will definitely affect the patient’s treatment effect and disease progress as well. How can doctors help patients face their tumors? Some relevant researches show that the average survival period of tumor patients with some of the following psychological behaviors are significantly prolonged: 1) they can always hold hope and confidence; 2) they can express or vent their negative emotions in time; 3) they can actively carry out meaningful and joyful activities; and 4) they can maintain close contact with people around them. On the contrary, negative psycho-behavioral responses accelerate the process of cancer deterioration. So, how should doctors help tumor patients to establish psychological support? 1.Correct the concepts In today’s medical development, many tumors can be cured, and there are more that can survive with the disease, and a piece of paper diagnosis is not equal to a death notice. Primary care doctors can use cognitive behavioral therapy to help patients establish correct cognition and correct the wrong concept of “tumor=death” in the face of disease. Let patients accept the new concept of “tumor ≠ death” from the inside, which can reduce the negative emotional reaction brought by the tumor. 2. Optimistic combat Doctors should pay attention to the medication and inform patients in advance of the adverse reactions that will occur in the process of treatment, such as vomiting, hair loss and other phenomena, so as to reduce the psychological pressure of the patients on the change of their appearance, enable patients to optimistically look at the treatment methods and effects, avoid the phenomenon of strong psychological reactions caused by physical diseases, and enhance the combat strength of the patients. 3.Partnership Encourage patients to actively participate in group therapeutic activities, such as anti-tumor club. In group activities, patients can understand each other’s pain and support each other. In the anti-tumor club, we can organize “talk therapy” between patients and tell other patients that even if they have tumors, they can also coexist with them.
