Breast cancer is one of the most common types of cancer in the world. It originates in breast tissue and can lead to serious consequences for a woman's health. One of the most common forms of breast cancer, the tumor has the shape of a spot. It grows slowly and does not cause concern, but it is very dangerous, since in 80% of cases it leads to the appearance of lymph nodes and metastases in the body. In addition, the disease is rarely detected at an early stage and is most often detected in advanced stages, when radical treatment is not possible.
