The stage of a cancer tells you how big it is and whether it has spread. The type tells which type of cell the cancer started from and the grade means how abnormal the cells look under the microscope.
Knowing the stage, type and grade of a cancer can help doctors plan your treatment.
The staging systems used for lung cancer can seem complicated. Ask your doctor as many questions as you need to in as much detail as you find helpful at this point. Lung cancer specialists are used to explaining things in a simple way that makes it easier to understand.
