Is lung squamous cell carcinoma a malignant tumor?

Lung squamous cell carcinoma is a type of malignant tumor; if physical discomfort occurs, prompt medical attention is recommended.

Lung squamous cell carcinoma is a malignant tumor and a subtype of lung cancer. It originates from squamous cells in the lung and is usually directly associated with long-term smoking. Squamous cells are a type of epithelial tissue lining the mucous membranes of the lungs, and lung squamous cell carcinoma develops when these cells undergo malignant transformation.

Lung squamous cell carcinoma is typically aggressive, capable of rapidly spreading within lung tissue and to surrounding tissues and lymph nodes. It can also spread to other parts of the body via the bloodstream or lymphatic system, forming distant metastases, which is one of the indicators of its high malignancy.

Lung squamous cell carcinoma cells exhibit highly malignant features in both morphology and biological behavior, including increased mitotic activity and cellular atypia. Long-term smoking is the primary risk factor for this cancer, as it causes DNA damage in lung cells, promoting tumor development.

In terms of daily care, one of the most effective ways to prevent lung squamous cell carcinoma is smoking cessation. For patients already diagnosed with this condition, early diagnosis and treatment are crucial. Supportive care, a healthy diet, and maintaining a positive mindset also have beneficial effects on patient recovery and quality of life.
