1. Lung nodules that grow too fast, nodules that double in size a week can basically rule out the possibility of lung cancer, lung cancer cells grow from malignant transformation to nodules visible to the naked eye It takes at least half a year, and most of those who grow up in the short term are infections.
2. Nodules with smaller diameters, lung cancer cells will not shrink by themselves, and anti-infective treatment will not make them change, so nodules with smaller diameters during follow-up can basically be Lung cancer was ruled out.
3. Nodules that have not changed for many years, no changes in the lungs for more than five years, and the possibility of malignancy can basically be ruled out. I have been a doctor for so many years, and the nodules have been followed up for more than 5 years. No more than 3 patients were diagnosed as malignant.
4. Completely calcified pulmonary nodules. Calcification means that the lesions are completely covered by calcium, which is equivalent to having stones in the lungs. Such nodules will basically not change. It will not turn into lung cancer.
5. A large cluster of nodules gather together. Most of this is not lung cancer. Lung cancer generally grows together and will not be scattered, especially if it grows around a large nodule. There are several nodules, which are basically infections, and the possibility of tuberculosis is relatively high.
