Cancer lung scales

Squamous cell carcinoma of the lung is a malignant epithelial tumor derived from the bronchial epithelium, which can show keratosis and / or intercellular bridge characteristics. Squamous cell carcinoma of the lung is more common in elderly men and is closely related to smoking. Squamous cell carcinoma, especially at the junction of skin and mucosa, is more likely to occur. Lung squamous cell carcinoma has slow growth, late metastasis, more opportunities for surgical resection, and higher 5-year survival rate. Lung squamous cell carcinoma is less sensitive to radiotherapy and chemotherapy than small cell undifferentiated cancer.
