Abstract

According to the International Agency for Research on Cancer, 2.3 million new cases of breast cancer were registered worldwide in 2020, which is 11.7% of all cancer cases. It is the fifth leading cause of cancer mortality in the world, which claimed the lives of 685,000 women in 2020. From 2006 to 2015, the incidence of breast cancer increased, during each year the increase was approximately 0.3% to 0.4%. Despite this, survival increased to 90% at all stages of breast cancer. The aim of the study was to identify the role of immunotherapeutic markers in triple negative and luminal B, HER2-negative breast cancer.
