8mm Invasive lung adenocarcinoma can be any of stages I, II, III and IV. Tumor size is only a part of staging, but also depends on lymph nodes and distant metastasis.
Invasive lung adenocarcinoma belongs to a kind of lung cancer. Clinically, TNM staging is used to stage lung adenocarcinoma, with T as primary tumor, N as regional lymph nodes and M as distant metastasis.
1. Firstly, T staging is based on the primary tumor, including T1, T2, T3 and T4, with different T values for different sizes, numbers and cumulative ranges.
2. Secondly, the lymph node metastasis can be seen by N, which is divided into N0, N1, N2 and N3. No lymph node metastasis is N0, local hilar lymph node metastasis is N1, ipsilateral mediastinal and/or subglottic lymph node metastasis is N2, and distant lymph node metastasis in the contralateral hilar, mediastinal, or cervical lymph nodes etc. is N3.
3. Finally, organ metastasis is expressed by M stage, which mainly depends on whether distant organ metastasis occurs through the blood; no metastasis occurs is M0, and metastasis occurs is M1.
In conclusion, 8mm cannot determine the stage of invasive lung cancer, and it is necessary to make clinical staging (I, II, III, IV) according to TNM staging. It is recommended that lung cancer patients who have been diagnosed clearly should seek medical treatment in time to avoid delaying their condition.
