What does "fibrous proliferative lesion in the left upper lung" mean?

Fibroproliferative lesions in the upper left lung are typically discovered during imaging examinations such as chest CT or X-ray, showing chronic proliferative changes in the lung tissue.

These fibroproliferative lesions may result from fibrous tissue proliferation following recovery or healing of prior pulmonary infectious diseases. They are commonly associated with old tuberculosis, chronic pneumoconiosis, chronic pneumonia, and interstitial lung diseases. In some cases, they may also arise due to pulmonary fibrosis or space-occupying lung lesions. If a fibroproliferative lesion is found in the upper left lung but the patient has no symptoms, treatment is generally not required; regular follow-up examinations are sufficient. However, if the lesion is extensive or accompanied by physical discomfort, further diagnostic evaluations are recommended to determine the underlying cause, followed by timely treatment under the guidance of a qualified physician.

During treatment, it is essential to get adequate rest and avoid strenuous physical activities. Diet should exclude greasy and irritating foods.
