Breast cancer is one of the tumors with the highest cure rate. It takes a lot of time and effort to treat and recover. Many breast cancer patients are prone to fall into various psychological misunderstandings, which delay the regular treatment and lead to the aggravation of the disease, which makes the mammography experts heart-broken. Tumor patients are especially prone to believe in online experience and folk medicine, thinking that these prescriptions can really cure their cancer. It is not known that these online gossips, prescriptions and miracle drugs of the so-called experienced people will not only save lives, but also delay the disease and treatment. 2.Small illnesses and pains sensitively thought to be related to tumor recurrence Clinically, many patients have become birds of a feather after getting breast cancer, and are very sensitive to all sorts of things. Coupled with the high rate of lost visits after tumor patients are discharged from the hospital. If they do not return to the hospital for follow-up, they will easily become paranoid when their body becomes sick. Over time, too much psychological pressure will also affect physical health. 3, to avoid formal treatment, unwilling to face reality Clinically there are a large proportion of patients, choose to avoid formal treatment, unwilling to face reality. This is actually a kind of escape psychology, which is still common among tumor patients. What doctors can do is to explain patiently and carefully, and join hands with patients’ families and friends to help patients understand their condition correctly and continue to receive regular treatment. Some patients feel that their disease will infect their family members or friends, or that others will look at them with different eyes, so they refuse to interact with others and close themselves up, living in chagrin, fear and injustice all day long. In fact, most of the breast cancer cases can be healed very well after regular treatment. Many patients live well for 10, 20 or 30 years after surgery, with a colorful and interesting life, and they do not feel different from others.
