With the popularization of CT, a term “glass grinding”, which was previously unnoticed by people, has entered people’s view. It is a professional term that has never before been seen in the imaging industry and is of great interest to young and middle-aged people. Baidu doctors” played a role in this process, people go online to find some bad news, “grinding glass” has become a “prequel” of “lung cancer”. “prequel”. If Chinese is an art, Chinese imaging doctors are artists, and “frosted glass” has evolved into “hairy glass”, “frosted glass”, “nodules”, “nodules” and “nodules”. “small nodules”, “small patches”; suffixes evolved into “frosted glass shadows”, “frosted glass foci” “frosted glass nodules”; prefixes evolved to “pure frosted glass”, “mixed density frosted glass”, “partially solid frosted glass “; English became “GGO”, “GGN”, “PGGO”, “MGGO “. ”With the popularity of CT health checkups, a large number of young and middle-aged employees were found to have “ground glass” in their lungs, and the doctor’s conclusion was initially The doctor’s opinion is that the disease must develop to a certain extent before the typical features appear, before that, the features are often not obvious, benign and malignant disease features may even cross and overlap with each other, the doctor’s risk of diagnosis is inversely proportional to the course of the disease, the more advanced the disease is easier to diagnose, the more early the disease is more likely to be misdiagnosed; the most vague, recommending follow-up CT at 3 months, 6 months, 1 year. The more advanced the disease, the easier it is to diagnose, and the more early the disease, the easier it is to misdiagnose; the most amazing thing is the “cure for the untreated disease” of Chinese medicine, the disease is beaten back by the Chinese medicine of the motherland before the onset of the disease, which is very similar to the treatment of “glass grinding”, because “glass grinding This is very similar to the treatment of “glass grinding”, because the most important “atypical adenomatous hyperplasia” and “adenocarcinoma in situ” are precancerous lesions, and their treatment is “treating the untreated”. The term “frosted glass” is a general term used to describe the morphology of the lesion, which means that the density of the lesion is as translucent as frosted glass, while the transparent ones are normal alveoli and the opaque ones are substantial nodules. Given the large proportion of “frosted glass” containing atypical hyperplasia, carcinoma in situ, microinvasive or invasive adenocarcinoma, it is necessary to pay attention to and learn from frosted glass shadows. The differentiation between true and false “ground glass” is a must for a specialist. “False” ground glass nodules are most often seen in cases where the diameter of a substantial nodule is less than the thickness of the image layer. These nodules are mostly granulomatous inflammation or old scar nodules, which are identified by 1-2 mm thickness CT image scanning; “pseudo” ground glass nodules also need to be distinguished from inflammatory patchy shadows, which appear flat in multiplanar reconstruction and do not constitute spherical nodular foci after 3D reconstruction. “Pseudo-inflammatory” ground glass nodules are most often seen in cases where the diameter of the ground glass nodule is less than the thickness of the image layer, for example, a 5mm ground glass nodule is patchy or striated “inflammation” on an image with a thickness of 10mm, identified by a 1-2mm thickness CT image scan. Patients’ eyes: Since the lung was found to have a ground glass shadow on physical examination, we have been consulting doctors everywhere, and only when we came into contact with them did we realize that this thing is like the devil, with many variations and various forms existing among benign and malignant symptoms, some doctors said to operate immediately, some said to observe, it is too torturous, and it is so difficult to make a clear diagnosis. When I first found out that I had a lung problem, I spent every day in depression. My whole life and state were disrupted by this, and whenever I was free, I would think about it, and I couldn’t sleep well at night, and my quality of life was not high. To the doctor’s point of view: I have looked up a lot of information, consulted many doctors, large and small, this grinding glass shadow can only be diagnosed by surgical pathology, what thin layer, what experience is useless, can only be benign and malignant which is the possibility of the size of the problem. Idiom medicine Q:Why was no ground glass nodule found in the previous physical examination? A: There is a big difference, just work in those years the unit unified chest film physical examination, chest film without the term glass, such a tight life but we live a very stable; now have a family, a full house, spend their own money to do CT physical examination, the disease to find the door; the old saying is good, when young with the body for money, after middle age spend money to buy health. Q:Chest X-ray and CT why the results will be different? A: Butcher, the human body is like a bun, the doctor is like a noodle master, the chest X-ray is to press the bun into a pie, and then the doctors put it in front of the lamp to see and guess what the filling is. Large tumors like walnuts are the easiest to diagnose, small nodules like raisins are hard to guess, and ground glass like bean paste are all missed, which is not the most difficult, because there will be meat, vegetable, sugar, and even more than two kinds of filling at the same time; CT is like a slicer, which cuts the bun into thin slices, so that the bun that was hidden deep does not show the filling, so a batch of small nodules are found. Q: Why are the CT results different from hospital to hospital, and how many nodules do I have? A: The blind man’s touch represents the true fate of multiple nodules, because different doctors and different thickness of CT scans directly affect the number of nodules shown. It is better to do a thin CT scan and then let an experienced doctor spend enough time to look carefully, like a sapper digging a mine, to mark each location, size and nature clearly, and better to give a precise and personalized treatment plan. Q:Surgery or follow-up observation? A:It is indecisive, doctors usually behave like this in front of diseases they are not good at, because any wrong diagnosis can bury the patient’s happiness for a lifetime, and good doctors feel guilty about it. The standard answer is based on authoritative statistical data, providing probability possibilities, usually 1 month for the first review, 3 months for the second review, then once every six months thereafter, then once a year, then once every two years. Q:Is CT radiation serious? A: It is said that CT radiation is very serious, and it is easy to cause cancer if you do it more often, but it is contradictory if you don’t do it and can’t detect cancer. In fact, the cumulative dose in a year should not exceed the safe dose for radiation workers (50 ho-sieverts) and you will be fine. Pregnant women and infants should avoid CT as much as possible, and couples should not be exposed to CT to the lower abdomen for three months before preparing to have a child. Q:Does Cordyceps and Tinctoria useful? A: It is not recommended to spend money to buy them. Chinese medicine is an auxiliary medicine that can play a regulating role, but the effect is not obvious for lung cancer treatment; sweat drops and grains are hard work, and what has been sent home is firmly eaten,. Q: Are front and back pain, joint pain and lymph node pain a manifestation of lung cancer? A: It is very rare to detect lung cancer because of the above mentioned discomfort, but early lung cancer does not have any signs.
