I often see this scene in the clinic, where patients come to the doctor worried: “Doctor, there is something wrong with my physical examination report, am I growing cancer?” On the report, various terms or descriptive language were written, such as “nodule”, “cyst”, “mass”, “BI-RADS “, “hypoechoic”, “anechoic”, “calcification”, “disorganized glandular structure “These professional or semi-professional words make the half-educated patients confused and confused. So, what is wrong with their breasts? To avoid unnecessary panic, let me briefly explain these words in order of their frequency. First: “nodule” This word is mostly found in the ultrasound report of the breast, and occasionally in the simple touch examination report and mammogram report. The term “nodule” is a descriptive term to describe a “small” mass found by various methods and does not relate to the benign or malignant nature of the mass and is never the name of the disease. The term “mass” is used to describe a “large” mass. Second: “hypoechoic”, “anechoic” In the ultrasound report of the breast, the nodule is usually described as “hypoechoic” or “anechoic”. “Again, this is descriptive language, and there seems to be no particularly objective criteria for defining “nodules” that are naturally darker (hypoechoic) or darker (anechoic) on a black-and-white ultrasound image of various nature. The terms “well-defined” or “poorly defined” describe whether these “nodules” are clearly identifiable on the image. It is not possible to say that “indistinct” is malignant or “clear” is benign; this requires specific analysis by the physician. Third: “disorganized glandular structure” is a descriptive term used to describe the glandular image in the ultrasound or mammogram report. If you imagine the breast as a bun (heh), then the skin and subcutaneous fat tissue are the “bun skin” and the glands are the “bun filling”, and the images always clearly distinguish the “skin” from the “filling”. The “skin” and the “filling” are always clearly distinguishable on the image, and the “filling” is the focus of our attention. If the image structure of the “filling” looks different from the normal one, we would describe it as “glandular structural disorder”, mostly due to glandular hyperplasia (microscopic changes in cell number, arrangement and tissue structure), which is often referred to as “Of course, we cannot exclude a very small number of “structural disorders” due to local cellular malignancy. The fourth place: “cysts” Again, in ultrasound reports, experienced sonographers will judge a particularly typical “non-echoic” nodule as a “cyst”. This is more common in cystic hyperplasia of the breast, which can be single or multiple. Most cysts are benign and harmless. The fifth place: “BI-RADS” This mysterious “high” looking English has caused many patients to panic, and what is even more frightening is the different levels on its suffix: grade 1, grade 2, grade 3…. …In fact, this is just an abbreviation for “breast imaging reporting and data system”, in order to make different doctors see the image report, there is a unified standard to find, when the classification R3 level When graded R3, it is a sign that the physician should make a further diagnosis or surgical intervention. Many patients are frightened by the word “calcification” on the mammogram report, not knowing that while calcification is very common in breast films, problematic malignant “calcifications” are very rare. Scattered, isolated, large, round calcifications (white dots on mammograms) are actually benign calcifications, and although they do not disappear once they are created, they will not become malignant for life and need not be bothered with. However, calcifications that are suspected to be malignant must be further treated by a physician. The specific diagnostic criteria will not be discussed here.
