Fibrous streaks do not become nodules per se, but nodular shadows may appear around them, although the probability is low and correlates with the presence of lesions in the tissue cells surrounding the fibrous streak. Fibrotic streaks are remnants of fibrotic tissue that appear after the lesion has been absorbed or treated, and the corresponding lesion is stable and mostly unchanged. In a small percentage of the population, cellular anisotropy occurs around the residual tissue, which further leads to cellular lesions and the development of peripheral nodules, which need to be evaluated in conjunction with the clinical examination, and then standardized treatment. Once there is nodule formation, it is very likely to be a manifestation of cancer, which needs to be further judged by puncture biopsy, and after determining the specific condition, standardized treatment will be carried out under the guidance of clinicians.
