With the continuous improvement of living standards, people’s demand for health is getting stronger and stronger, not only do they want their bodies to be free of disease, but they also want to be comfortable, and the process of seeking medical treatment is not only limited to the pursuit of the amount of cost and the degree of comfort, but also the strong pursuit of minimally invasive and cosmetic, which is a trend. Outpatient visits, people want to do an ultrasound, found a problem, want to review an ultrasound, physical examination also put ultrasound into the self-help package. As a result, a large number of “ultrasound found nodule” problems appear in the outpatient clinic, and the doctor receives them one by one and repeats the explanation one by one, and a large amount of work is thus generated. I have analyzed some of the causes of “ultrasound nodules”, and I hope that when you encounter similar problems, you can refer to them, analyze them on your own, and find a solution that suits your needs. Among them, minimally invasive rotary excision under ultrasound localization should be a good choice. Purpose: to be able to take the nodule tissue and sent to the pathology examination to help clarify the diagnosis can meet the needs of cosmetic.
