Japanese: colposcopy

…It was first used in European countries, mainly in Germany, but was introduced to Japan after World War II and has been widely used since the 1950s, and since 1970 has spread all over the world, including the United States. Examination using a colposcope is called colposcopy, which searches for minute changes that cannot be seen with the naked eye, such as the color tone of the cervical mucosa and the properties of the microvessels found there, and not only helps to identify the location and spread of malignant lesions from the findings and identify the optimal biopsy site for histopathological diagnosis, but also makes it possible to estimate the malignancy of the lesion itself. It is a completely painless examination, and, together with cytology, is an essential method for early diagnosis of cervical cancer. …
