The severity of breast cancer is more related to the stage of the disease and the degree of cell differentiation, and less related to whether it occurs in the left or right breast.
Breast cancer is a common malignant tumor in women, and the occurrence of the disease is related to heredity, gene mutation, hormone level and other factors. The criteria for determining the severity of the disease are mostly TNM stage and the degree of differentiation of cancer cells.
TNM staging is the development of primary tumor, the degree of lymph node metastasis, and whether distant metastasis occurs. It can often be divided into four stages, in which the later the stage, the more complicated the condition, the more serious the disease, and the worse the prognosis.
In addition, the degree of differentiation of tumor cells is also related to the severity, which can be divided into three levels: high, medium and low, and the higher the grade, the worse the degree of differentiation and the worse the prognosis.
