At the 29th National Cancer Prevention and Control Promotion Week, tumor related topics have become the focus of attention. In recent years, many people have been diagnosed with "nodules" during physical examinations, and some are even worried about the risk of cancer. What exactly is a nodule? Do nodules necessarily develop into cancer? How to prevent and treat nodules? The reporter conducted an interview on this matter. The detection rate of nodules is on the rise. Mr. Bai, a resident of Taiyuan, Shanxi, recently underwent a physical examination and the examination report showed nodules in the thyroid gland. I'm confused in a moment, I don't know what a nodule is. "Mr. Bai asked the people around him, and some said that the nodule is not a big deal. Eight out of ten people have nodules, while others said that a nodule is accidentally cancer and needs to be surgically removed as soon as possible. For several days, I have been feeling uneasy and I am planning to go to the hospital to register and ask. In recent years, many people like Mr. Bai have been diagnosed with nodules. Recently, Meinian Health Group released its 2022 physical examination big data blue book, which showed that the detection rate of lung nodules was 54%, thyroid nodules was 47%, and female breast nodules was 31.5%. A health report by Aikang Group on the physical examination population in Wuhan City shows that the detection rate of breast nodules increased by 12.77% from the 2019 to 2023 versions of the report. The reporter interviewed multiple experts and learned that the "nodule" in the physical examination report is not the name of the disease, but a descriptive term in imaging. It only represents the "small lump" seen on the body through imaging examination, and tissue proliferation, inflammation, benign or malignant tumors may be the cause of the "small lump". In recent years, the detection rate of nodules has indeed shown an upward trend, but this phenomenon has multiple reasons. "With the accelerated pace of life and the increasing pressure of life, some people have formed unhealthy lifestyles, such as sleeping late and getting up late, overeating, lack of exercise, poor sleep, and the aging of the population, making the incidence rate of some nodules and malignant tumors continue to rise." Deputy Chief Physician of Breast Surgery, Cancer Hospital, Chinese Academy of Medical Sciences Qi Liqiang, director of breast surgery of Shanxi Hospital, Cancer Hospital of the Chinese Academy of Medical Sciences, said. The enhancement of public awareness of physical examination is also an important reason for the increase in nodule detection rate. Qi Liqiang said that in the past, most people only went to seek medical treatment when they had obvious symptoms. Now, with the continuous improvement of health awareness, more and more people actively participate in physical examinations and early screening for cancer, and more and more diseases are discovered in the early stages. In addition, the improvement of detection rate is also related to the improvement of detection level. Lian Jianhong, director of thoracic surgery Department of Shanxi Hospital, Cancer Hospital of the Chinese Academy of Medical Sciences, said that in recent years, the precision of CT, B-ultrasound and other detection instruments has been increasing, and doctors' experience has also been growing, making smaller nodules can also be detected. Do nodules necessarily develop into cancer? Many people associate nodules with cancer after physical examination, so do nodules necessarily develop into cancer? Several interviewed experts told reporters that only a very small number of nodules will be diagnosed with cancer, and the vast majority of times there is no need to worry too much. One theory is that in most cases, the distance between nodules and cancer is as far as a primary school student considering whether to attend Tsinghua or Peking University. The reporter learned that various organs, including the kidneys, liver, ovaries, and uterus
