Abstract

All over the world, the most common malignancy in women is breast cancer. Breast cancer is also a significant factor of death in women. In 2020, approximately 2.3 million cases of breast cancer were newly diagnosed in women globally, and approximately 685,000 people died. Breast cancer incidence varies by region around the world, but it is all increasing. According to the current morbidity and mortality trend of breast cancer, it is estimated that by 2030, the number of incidence and deaths of breast cancer will reach 2.64 million and 1.7 million, respectively. The age-standardized incidence rate was 66.4/100,000 in developed countries and 27.3/100,000 in developing countries. The incidence of breast cancer in the world is increasing rapidly, and the incidence rate has increased by 57.8% in the past 30 years, and the rate of increase is 0.5% per year. The incidence and mortality of breast cancer among Chinese women rank first in the world, and in recent years, the incidence and mortality of breast cancer among Chinese women have also been on the rise. Breast cancer is a disease caused by a variety of factors, such as genetics, estrogen levels, environment, and behavior and lifestyle. The purpose of this review is to explore the global epidemiology, associated risk factors and molecular types of breast cancer to understand breast cancer prevalence, mortality, and to help with its prevention, early detection, treatment and improvement of prognosis.
