The difference between early lung cancer and early lung cancer

The main difference between early-stage lung cancer and early-stage lung cancer is that they are in different stages. Early-stage lung cancer is much earlier than early-stage lung cancer, and the former has a better prognosis after surgical treatment.

Most lung cancer patients go through a process of atypical adenomatous hyperplasia → carcinoma in situ → microinvasive adenocarcinoma → invasive adenocarcinoma. Among clinical primary lung cancers, the more common carcinoma in situ is an indolent tumor that grows slowly and rarely metastasizes to lymph nodes. It is called early lung cancer, usually earlier than early lung cancer. The lesion can be removed under thoracoscopy, and then combined with local lymph node sampling. After surgical resection, the survival rate can reach about 100%.

Patients with early-stage lung cancer may have a smaller tumor, no lymph node metastasis or distant metastasis, and no obvious clinical symptoms. They are usually found during chest CT scans. Although the probability of cure after surgical resection is relatively high, it is not as high as the cure rate of early-stage lung cancer.
