What is the difference between N1 and n0 lung cancer?
N0 – means there is no cancer in any lymph nodes N1 – there is cancer in the lymph nodes that are nearest the affected lung N2 – the cancer is in lymph nodes in the middle of the chest (mediastinum) on the same side as the affected lung or there is cancer in lymph nodes just under where the wind pipe branches…
What does N1 N2 mean on a chest xray?
N1 means there are cancer cells in lymph nodes within the lung or in lymph nodes in the area where the lungs join the airway (the hilum). N2 N2 means there is cancer in lymph nodes: in the centre of the chest (mediastinum) on the same side as the affected lung or
What does a N3 Lymph node nodule in lung cancer mean?
N3 means there is cancer in lymph nodes: 1 on the opposite side of the chest from the affected lung or 2 above the collar bone or 3 at the top of the lung
What does n0 lymph node cancer mean?
N0 means that the lymph nodes don’t contain cancer cells. N1 means there are cancer cells in lymph nodes within the lung or in lymph nodes in the area where the lungs join the airway (the hilum). Metastasis (M) describes whether the cancer has spread to a different part of the body.
