Now, the liquid biopsy program (Lung Nodules) introduced by Akcome can assist in the identification of benign and malignant lung nodules by detecting lung cancer-related ctDNA in the blood. This is non-invasive and convenient, which can avoid causing panic or delaying treatment, and is ideal for the middle-aged and elderly population.
Solid density nodules over five millimeters can be considered benign if they are stable for two years of follow-up, and sub-solid density nodules over five millimeters can be treated as benign if they are stable for more than five years of follow-up. For nodules in this category, annual CT review is usually sufficient. Usually, we call round or oval space-occupying lesions directly smaller than 3 cm isolated pulmonary nodules, which are surrounded by lung parenchyma and have no associated lymph node enlargement, atelectasis, or pneumonia at all. Those directly smaller than 2 cm are called small intrapulmonary nodules, and those directly smaller than 5 mm are called micronodules.
Pulmonary nodules are round or irregular lesions with a diameter of less than or equal to 3 centimeters in the lungs, seen as a bright spot on CT or magnetic **** vibration, which can be large or small; can appear alone or in groups of three or five; can be solid or have a cavity; can have a burr or a smooth surface ...... its form It can be solid or hollow; it can have burrs or a smooth surface Its form is ever-changing and its significance is varied. With the improvement of the population's health concept and medical level, routine medical checkups have gradually entered people's lives, and lung cancer screening through imaging is an indispensable part of medical checkups.
Produced and secreted by tumor cells and released directly into the blood, body fluids, and tissues, tumor markers provide guidance for tumor diagnosis, classification, prognosis, and treatment, and they can play a role in early diagnosis of patients with isolated lung nodules. To be honest, sometimes I don't dare to say 100% that this nodule is benign or malignant. It's like the police arresting someone, which one is the bad guy and which one is the good guy, there has to be evidence. When the evidence is not enough, but also have their own experience and intuition.
