Metastasis may also occur in early stage of lung cancer, so it is recommended to follow the doctor’s instructions for regular review after surgery.
Lung cancer is a common malignant tumor of the respiratory system, and its occurrence is related to smoking, heredity and other factors. The clinical staging of lung cancer is mainly based on tumor size (T), lymph node metastasis (N) and distant metastasis (M). Early stage lung cancer refers to the tumor lesion with a diameter of less than 3cm, without lymph node and distant metastasis. Therefore, patients with early-stage lung cancer can mostly be resected by radical surgery and have a better overall prognosis.
However, if early-stage lung cancer patients fail to undergo standardized diagnosis and treatment in time, the disease may gradually progress to intermediate or advanced lung cancer, with lymph node metastasis and distant metastasis, at which time the condition is complicated and the treatment becomes more difficult. Therefore, it is recommended that early-stage lung cancer patients should go to regular hospitals as early as possible, follow the standardized diagnosis and treatment advice of specialists, and have regular follow-ups.
