Problems solved by technology

Traditional methods of drug administration for treating breast diseases are mostly carried out through intravenous injection or oral administration, but none of the above-mentioned drug administration methods can make the drug reach the lesion site directly, but allow the active ingredients to reach the affected area through intestinal absorption or internal circulation. In the process of absorption or circulation, the drug effect is often lost, and the therapeutic effect is greatly reduced. Especially when treating special groups such as stomach patients and pregnant women, intravenous or oral administration will also affect the patient's lactation and intestinal digestion. function causing severe additional damage
