Triamcinolone is an estrogen antagonist, which can block estrogen by directly competing with target organs for receptors, and its clinical application is characterized by immediate effects, which can play a certain role in relieving pain and eliminating lumps. It is commonly used in clinical practice and is the drug of choice. Because its competition for estrogen is not only limited to the breast, but also to other estrogen targets such as the vagina and endometrium, triamcinolone is prone to side effects such as menstrual disorders, leucorrhea, loss of libido, irritability and nausea after a period of time.
