Tuberculosis of breast, also known as tuberculous mastitis, is a chronic and specific infection of the breast. This disease is rare, but not uncommon. Cooper first described this disease in 1829, and Chen Shunming first reported this disease in my country in 1930. Breast tuberculosis is common in lactating women, and there are two types: primary tuberculosis of breast and secondary tuberculosis of breast. The former is mostly caused by damage to the breast skin, and the latter is often secondary to chest tuberculosis lesions or secondary to tuberculosis in other organs. Therefore, when treating local breast lesions in clinical practice, systemic anti-tuberculosis treatment should also be carried out. Traditional Chinese medicine has also conducted in-depth research on this disease. Depending on the causes of its formation, this disease is called breast tuberculosis, breast leukorrhea, breast habit, etc. It is also believed that this disease is mostly caused by anger damaging the liver, worry damaging the spleen, resulting in qi stagnation and phlegm coagulation, and Chong and Ren disorders, poor circulation of qi and blood, which lead to the onset of the milk network. Over time, heat accumulates and rots, which break through and leak. The pus is clear and thin, mixed with rotten cotton. Long-term pus discharge leads to damage to qi and blood, and the disease is delayed.
