Stages, types and grades of lung NETs
The stage of a neuroendocrine tumour (NET) tells you its size and whether it has spread. The type is the type of cell the tumour started in. And the grade means how abnormal the cells look under the microscope.
The tests and scans you have to diagnose a lung NET give information about the type, stage and grade. This helps your doctor decide which treatment you need.
