What grade is your lung cancer?
BMJ Group Medical Reference
Doctors may examine a sample of your lung cancer under the microscope. This helps them grade the cells according to how they look.
Healthy lung cells are described by doctors as well differentiated. This means they look like other healthy lung cells and have all the parts they need to work normally. Lung cancer cells don't look and work like healthy lung cells. They are called less well differentiated.
Lung cancers are graded as shown in the table below. The grade of your cancer indicates how fast it is likely to grow. G1 is the slowest. G4 is the fastest.
|GX||Grade has not been assessed.|
|G1||Lung cancer cells are well differentiated.|
|G2||Lung cancer cells are moderately differentiated.|
|G3||Lung cancer cells are poorly differentiated.|
|G4||Lung cancer cells are undifferentiated.|
