Among lung cancers, small cell lung cancer has the worst prognosis, while adenosquamous lung cancer belongs to non-small cell lung cancer, which has better prognosis than small cell lung cancer.
Lung adenosquamous carcinoma refers to the coexistence of clear adenocarcinoma and squamous carcinoma tissue structure in the same tumor tissue, with high malignancy, lymph node metastasis rate and local recurrence rate significantly higher than that of lung adenocarcinoma or squamous carcinoma, and has a poorer prognosis, but it is not the most serious among lung cancers.
The most serious lung cancer is small cell lung cancer, which is a group of highly malignant epithelial tumors composed of small cells of uniform size, including small cell carcinoma and compound small cell carcinoma. Small cell lung cancer is characterized by early and rapid proliferation and extensive metastasis. Most of the small cell lung cancer is found to have metastasis in brain, liver and kidney.
Specifically, one should go to the hospital and consult the doctor to avoid delaying the condition.
