With the development of modern medical technology, most of the diseases of the body can be effectively treated. However, for those invisible illnesses, such as problems with the internal organs or lesions, endoscopy becomes the doctor's eyes and hands. It can examine many diseases and see the lesion site more clearly. In addition, many doctors also use endoscopic examination for treatment. Now let me tell you what endoscopy is.
