For acute mastitis, one should first consult the Department of Mammary Surgery or Thyro-Mammary Surgery. When some hospitals lack a specialized breast surgery department, patients typically consult the general surgery department or gynecology department. If it is during the night or none of the specialized departments are available, then the emergency surgery department should be consulted. Thus, there are multiple relevant departments for acute mastitis. In larger hospitals with specialized departments, one can directly consult the Department of Mammary Surgery or Thyro-Mammary Surgery. During off-hours, nights, weekends, or other emergency periods, it is appropriate to consult the emergency surgery department.
