A 46-year-old middle-aged female “patient” came to my clinic with a very heavy face and deep dark circles under her eyes caused by lack of sleep. She was choked up and told me about a “demon” that had been bothering her for more than half a year – a 7mm nodule in the upper lobe of her left lung was found during a CT checkup a month ago. She had been thinking that it was cancer and had made her own “aftercare” arrangements. I took a look at the film she brought with me and found that there was indeed a ground glass shadow in the upper lobe of the left lung six months ago, about 5mm-1cm, and it was still multiple, and the shape was not like a typical tumor. She wondered, “I have cancer, why do I need anti-inflammatory drugs?” A month later she came back to my clinic with tears in her eyes and said that the “nodules” had disappeared! I compared the films carefully and found that the nodules had indeed faded or even disappeared, and told her, “It’s okay!” She breathed a deep sigh of relief, as if her whole body had relaxed. I remember it was an early morning, and the early winter sunlight bathed us in extra warmth. It was the happiest moment for her lover, herself and me, because another “patient” was free from the “tumor”. With the popularization of low-dose CT and the aggravation of haze, more and more patients are now found to have small nodules and ground glass shadow, and most of the patients and their families are very nervous to have surgery and cannot understand the advice of “observation” and “anti-inflammation”. Most of the patients and their families are very nervous to have surgery, and they cannot understand the advice of “observation” and “anti-inflammatory”, and they go around to “experts” for fear of delay, and some of them even threaten or even force the doctor to do the surgery, and finally a considerable number of patients cut out a piece of “pneumonia” or “tuberculoma”. “These benign nodules do not require the risk of removing a lung lobe at all. The largest percentage of patients in my clinic are these “small nodules”, so the most helpful and valuable test for these patients is regular review. Some patients may ask, “Will it be delayed for 3 months and if it is really cancerous, it will spread? In my 30 years of medical practice, I have never delayed my patients’ diseases. Because the growth of tumor has a certain cycle, especially when the nodule is small, 3 months is enough time for the doctor to see its changes, but it is not big enough for it to grow enough to spread and metastasize. For small nodules, what is “good” and what is “bad”, simply put, what grows is bad, and dynamic observation is better than all tests! If you find a small nodule, you can come to my clinic and I will personally show you the film and draw each nodule. Most importantly, I hope that every patient who comes to see me in my clinic can first get rid of the mental stress.
