Abstract

Breast cancer is the malignant tumor with the highest morbidity and mortality in women [1]. According to the latest cancer report of the World Health Organization (WHO) for 2020, new patients with breast cancer accounted for 2.26 million (11.7% of new cases), surpassing lung cancer (11.4%) for the first time as the most common type of cancer worldwide [2]. The morbidity and mortality increased year by year, rapidly increased with age after 30 years old, and reached the peak at about 55 years old. With the development of diagnosis and treatment technology, the survival rate and survival time of patients with breast cancer are increasing year by year. The 5-year survival rate can reach more than 85%. In a sense, breast cancer has become a chronic disease. At the same time, we must see that the mental health in patients with breast cancer has become an important factor affecting the quality of life [3]. While we are concerned about the treatment of malignant tumor itself, we should also pay attention to the psychological harm caused by tumor and treatment itself to patients with breast cancer. Studies have shown that demographic factors such as age, residential area, education level and marital status have different effects on the psychological distress level of patients with breast cancer [4].
