In the early stage of cancer, a series of changes will occur in psychological activities, which are summarized as the following common characteristics: anxiety, anger, depression, despair, suspiciousness, adaptation disorder, etc. The appearance of these characteristics varies from person to person, and is related to age, gender, occupation, education level, living condition, etc. All characteristics may not appear in the same patient, and the degree of reaction varies, so the adjustment should be targeted. Many years of clinical experience tells us that men’s tolerance is not as good as women’s, the higher the level of education, the more suspicious, often easy to delay the best time for treatment (repeatedly understand the condition, the Internet, check medical books, multiple hospitals for evidence, the combination may be a different idea) think too much is not conducive to treatment. On the contrary, I have seen a patient with some mental retardation in the late stage, but his family members coaxed him to cure the disease every day. Only those with mental disorder can do it, but to make sense out of this panic as soon as possible, shorten the cycle of psychological characteristics in the early stage of the disease, adjust their emotions and become rational, cooperate with family members and doctors to choose the best treatment plan is the best policy. Believe in science, establish the belief to overcome the disease, and actively cooperate with the medical staff to complete the treatment process. It is never advisable to listen to the disease or ignore it. It is especially important to find experienced doctors to work out the best treatment plan with family members and the positive attitude of patients to overcome the disease. Nowadays, there is a misconception in the society about the attitude towards tumor, after the tumor is just found out, the family members try to hide the disease from the patient, worrying that the patient can’t accept the reality, refuse the treatment and can’t think about the unpredictability ・・・・・・ This is totally wrong, the clinical work experience proves that most of the patients who can overcome the disease and recover are the ones who understand their own condition, imagine how to face the tissue and organ resection, radiotherapy and chemotherapy. The systemic and local reactions of radiotherapy and chemotherapy. Family members cover up, stammering communication, to the patient increased psychological burden, resistance to intensify, is not conducive to treatment and recovery. A successful treatment case is to tell the patient the truth about the disease, encourage the patient to strengthen the confidence to overcome the disease, and the patient can communicate more smoothly with the family and medical staff after being informed. It is proved that open treatment is more conducive to the recovery of cancer patients. Psychologists have categorized the emotions of cancer patients into four types: disbelief, hopelessness, bland acceptance, and struggle.
