Plasmacytoid mastitis is known as the undead cancer, which was previously known as a rare disease, and with the change of living habits and living environment, the incidence is rising. According to incomplete statistics from the Breast and Thyroid Department of Chongqing Hospital, the number of new admissions to our department in one month is the same as the number of cases in Chongqing in one year 10 years ago. The more popular management of plasmacytoid mastitis today is abscess excision or mass excision, but the recurrence rate of plasmacytoid mastitis has not been affected. Most patients with plasmacytoid mastitis have surgery, most of which are multiple surgeries, up to 12 incisions. Traditional Chinese medicine has been explored in the treatment of plasmacytoid mastitis and has achieved proven effective, less invasive treatments with low recurrence rates. One of them is the medicine twist, a paper twist with herbs. The toothpick-sized treatment tool replaces the scalpel, and the needle-point-sized wound replaces the scarring. The principle of the medicine twist is that the herbs are delivered directly to the center of the lesion, removing the undead cancer, through the spiral structure of the medicine twist and the effect of the herbs to dissolve the decay and regenerate the muscle. Most patients have no significant deformity change from the pre-onset breast after treatment. The medicine twist has been operating in our country for centuries and has been instrumental in chronic diseases. This concept coincides with foreign reports, where a large number of reports support that plasmacytic mastitis does not recommend sex abscess excision, which brings much more damage than the therapeutic effect.
