Lung nodules vary according to the type and size of the nodule and the presence of risk factors and other review times. They can be categorized into solid nodules, partially solid nodules and ground glass nodules.
1. Solid nodules: If the diameter of a single solid nodule is ≤8mm and there are no risk factors, it is recommended that the examination be repeated once every 6-12 months; if the diameter of the nodule is >8mm, the examination can be repeated once every 3 months. If there are one or more risk factors (e.g. long-term smoking history, history of lung cancer in close relatives, etc.), the review time can be directed by the doctor according to the size of the nodule.
(1) Nodule diameter ≤4mm, can be reviewed every 12 months.
(2) If the diameter of the nodule is 4-6mm, the examination can be done at 12 months, and if there is no change, it is recommended that the examination be done once a year.
(3) If the diameter of the nodule is 6 to 8 mm, it can be reviewed at 6 to 12 months, and if there is no change, it can be reviewed again at 18 to 24 months, after which it can be reviewed once a year.
2. Partially solid nodules: nodules ≤8mm in diameter can be reviewed at 3, 6, 12 and 24 months, and then annually if there is no change. For nodule diameter >8mm, it is recommended to review every 3 months.
3. Ground glass nodule: if the diameter is ≤5mm, it can be reviewed at half a year, and if there is no change, it is recommended to review annually; if the diameter is >5mm, it is recommended to review at 3 months, and if there is no change, it can be reviewed annually.
When you find lung nodules, it is recommended to improve the examination in time to clarify the cause of the disease, standardize the treatment under the guidance of the doctor, and review regularly to avoid delaying the condition.
