Is it true that lung squamous cell carcinoma rarely recurs?

Lung squamous cell carcinoma may recur after surgery. Surgery is currently an important treatment for lung squamous cell carcinoma, but some patients may experience recurrence and metastasis after the procedure, primarily influenced by the following factors:

Some patients with lung squamous cell carcinoma have oncogene mutations; even if the tumor is surgically removed, new tumors may still develop in other areas.

Surgery can only remove visible tumors, and some latent cancer cells may not be completely eliminated, leading to possible postoperative recurrence. Therefore, adjuvant treatments such as radiotherapy or chemotherapy may be necessary after surgery.

Unhealthy lifestyle habits. Smoking, alcohol consumption, and staying up late after surgery can reduce the patient's immunity and increase the risk of lung squamous cell carcinoma recurrence.

In advanced-stage lung squamous cell carcinoma, radical surgical resection cannot achieve a cure. Instead, it is combined with chemotherapy to alleviate symptoms, reduce suffering, and prolong survival, although the recurrence rate remains very high. Treatment of lung squamous cell carcinoma is mainly based on comprehensive staging: for early-stage cases, radical surgery is recommended whenever possible, with a 5-year survival rate above 80% and a recurrence rate around 20%.
