What is a mammography target? How often is it appropriate to do a mammography? Mammography is known as mammography and is recognized as one of the best methods for routine clinical examination of breast cancer and breast cancer prevention screening. Let's take a look at this imaging method.
What is a mammography target?
Mammography, full name mammography, also known as molybdenum and palladium examination, is currently the first choice for diagnosing breast diseases and the simplest and most reliable non-invasive detection methods, relatively small pain, simple and easy, and high resolution, good repeatability, left images for before and after comparison, not limited by age, body shape, has been used as a routine examination. It is characterized by the detection of breast masses that cannot be touched by doctors, especially for large breasts and fatty breasts, its diagnosticity can be as high as 95%, for stage T0 breast cancer (clinical outpatient negative) with a small amount of microcalcification, it can only be detected and diagnosed early by soft X-ray examination, and the diagnostic sensitivity to breast cancer is 82% to 89%, and the specificity is 87% to 94%.
The role of molybdenum targeting
1. It can be used as a relatively noninvasive examination method, which can comprehensively and correctly reflect the general anatomy of the entire breast;
2. X-ray examination can be used to observe the influence of various physiological factors (such as menstrual cycle, pregnancy, lactation, labor and endocrine changes, etc.) on the structure of the breast, and can be dynamically observed;
3. Benign lesions and malignant tumors of the breast can be reliably identified;
4. According to X-ray examination, some precancerous lesions can be found, and follow-up film observation can be carried out;
5. Follow-up examination of breast cancer patients after radiotherapy and chemotherapy, observe the efficacy, and regularly monitor the healthy breast.
How often is it appropriate to do a molybdenum scan?
Molybdenum is the most effective method of early diagnosis of breast cancer, and the best time to detect it is 3-5 days after the end of menstruation or about the 10th day of menstruation. It is recommended that women over the age of 35 who have given birth have a molybdenum scan once every one to two years. Since the molybdenum target has a certain radiation dose, it is not advisable to check for excessive frequency.
