Patients with blocked mammary glands can have the following symptoms: First, pain: there can be a slight hidden pain in the breast or a persistent swelling and pain. Second, redness and swelling: If it is caused by mastitis, then the skin can appear significantly red, even broken, fluid out of the body, and sometimes the outflow of fluid is foul-smelling. Third, the mass: local mass can be touched, the mass can be large or small, commonly in mastitis, but a small number of patients are caused by malignant tumors of the breast, so the mass is more closely adhered to the surrounding tissue, the boundary is unclear. When a blocked breast is found, it should be disposed of at the general surgery or breast surgery department of the hospital as soon as possible. If the condition allows, breast ductoscopy can be performed, and if the condition is more serious, surgery may be required. During the treatment period, fresh fruits and vegetables can be consumed appropriately, and low-fat high-quality protein can be consumed appropriately to promote the body to recover as soon as possible.
