1. What is the TNM system?
The stages of lung cancer are classified by the TNM system, which stands for Tumour (T)- Nodes (N) - Metastasis (M)
Tumour means tumor (T) - describes the size of the tumor and how far the cancer has spread into the lung tissue. Tumors can be classified from T1a (describe a tumor less than 1cm) to T4 (describe a tumor larger than 7cm).
Nodes (N) - describes how far the tumor has spread to nearby lymph nodes. Nodes can be classified from N0 where there is no spread, to N3 where the cancer has spread to other areas of the body, such as the other side of the chest or collarbone.
Metastasis means metastasis (M) – answers the question of whether the cancer has spread to other areas of the body outside of the lungs. Metastasis can be classified from M0, i.e. where there is no spread to M1c i.e. where the cancer has spread to other organs of the body and created additional tumors.
