Is solid lung cancer definitely invasive?

Solid lung cancer may be invasive lung cancer, may also be non-invasive lung cancer, the need for pathological diagnosis. Solid lung cancer is not necessarily invasive lung cancer. Lung cancer is mainly divided into non-small cell lung cancer and small cell lung cancer, which can be further divided into non-small cell lung cancer, adenocarcinoma, squamous cell carcinoma, large cell carcinoma and other subtypes. Invasive lung cancer refers to the lung cancer cells break through the basement membrane of the alveolar wall, to the surrounding tissue infiltration growth, while solid lung cancer refers to the imaging examination (e.g., X-ray, CT, etc.), the internal structure of the shadow with increased density in the lung may be solid, or partial solid or ground glass density. Therefore, solid lung cancer may be invasive lung cancer or non-invasive lung cancer, and the specific diagnosis needs to be confirmed by pathological examination. Pathological examination is the gold standard for the diagnosis of lung cancer. Through pathological analysis of lung lesion tissues, the type, differentiation degree, infiltration range and other information of lung cancer can be determined, so as to provide basis for the selection of treatment schemes. For patients with solid pulmonary nodules, doctors usually evaluate the malignant risk of nodules comprehensively according to the characteristics of nodule size, shape, density, doubling time, etc., as well as the patient's age, smoking history, family history, etc. For nodules with higher malignant risk, further biopsy or surgical resection may be recommended to confirm diagnosis and treatment. For the diagnosis and treatment of lung cancer, a variety of factors need to be considered, including the patient's overall health status, tumor characteristics, treatment goals, etc. If you or your family members are diagnosed with lung cancer, it is recommended to consult a professional doctor in time to understand the detailed condition and treatment plan, and actively cooperate with the treatment.

At the same time, early diagnosis and treatment of lung cancer is very important to improve cure rate and survival rate. Regular lung cancer screening is recommended, especially for high-risk groups (such as long-term smokers, family history of lung cancer, etc.).
