What does physical examination mean for lung precancerous lesions?

Physical examination of lung precancerous lesions refers to abnormal changes in lung tissue that have not yet developed into lung cancer. Histologically, they are defined as atypical hyperplasia, carcinoma in situ and tiny non-cell carcinoma. This lesion can usually be found by CT image examination, but it needs lung biopsy to be diagnosed. Physical examination of lung precancerous lesions is an important index for early diagnosis of lung cancer. Timely detection and treatment can greatly improve the survival rate and therapeutic effect of patients.

Because lung cancer is one of the common malignant tumors, and the formation of most lung cancers requires a long-term development process of internal lesions, it is particularly important to check the precancerous lesions of lung cancer. If we ignore the early lesions and wait until the tumor develops into lung cancer, it is not only difficult to treat, but also ineffective. In addition, lung precancerous lesions usually have no obvious symptoms and are easily ignored, leading to irreversible deterioration of the disease.

Methods to prevent and treat precancerous lesions of lung include quitting smoking, avoiding contact with air pollution sources, maintaining a healthy diet and physical exercise. At the same time, regular lung imaging examination and lung function examination, as well as necessary examinations such as lung biopsy according to doctor's advice, can find and treat lung precancerous lesions as soon as possible in physical examination. In addition, if you have lung precancerous lesions, the treatment is similar to lung cancer, including surgical resection, radiotherapy and chemotherapy. Everyone's treatment should be based on the condition and individual differences.
