What Does Lung Squamous Cell Carcinoma Mean?

1. Lung squamous cell carcinoma is a type of non-small cell lung cancer, referring to a cancer type characterized by keratinization and intercellular bridges.

2. Also known as squamous cell carcinoma, lung squamous cell carcinoma is a malignant tumor originating from the bronchial epithelial surface. In imaging studies, the cancer appears as verrucous masses or infiltrative plaques with a hard texture, which may form ulcers after central ulceration. Histopathological examination of biopsy samples may show features of keratinization and intercellular bridges. Some cancer cells may be spindle-shaped. It is a common type of lung cancer, accounting for 40% to 50% of primary lung cancers.

3. Compared with small cell lung cancer, this type develops slowly with a relatively lower malignancy, and there are basically no signs in the early stages. In the middle to late stages, symptoms such as cough, expectoration, frequent hemoptysis, and chest pain may appear. The main treatment methods include surgical resection, radiotherapy, chemotherapy, and targeted drug therapy. If detected and treated early, the five-year survival rate can reach 70% to 80%. However, if diagnosed in the late stage, the prognosis is often unfavorable, with an average survival time of 1 to 2 years.

4. It is recommended to seek medical attention as soon as possible after experiencing signs such as cough, expectoration, chest tightness, and shortness of breath to identify the specific cause and receive targeted treatment. Those with a family history of lung cancer, occupational exposure history, or long-term smoking history should regularly undergo targeted cancer prevention screenings to avoid being unaware of the cancer. It is also recommended to maintain good personal care in daily life, such as quitting smoking and alcohol, and maintaining a light diet.
