Lung cancer stages-there are four stages of
lung cancer Once your lung cancer has been diagnosed, your doctor will work to
determine the extent stage of your cancer. Your cancer’s stage helps you and
your doctor decide what treatment is most appropriate. Keep on reading if you like to know more

Staging
tests may include imaging procedures that allow your doctor to look for
evidence that cancer has spread beyond your lungs. These tests include CT
scans, magnetic resonance imaging (MRI), positron emission tomography (PET) and
bone scans. Not every test is appropriate for every person, so talk with your
doctor about which procedures are right for you.
Stages of lung cancer
Lung cancer is divided into four stages.
Stage
I. Cancer is limited to the lung and hasn’t spread to the lymph nodes. The
tumor is generally smaller than 2 inches (5 centimetres) across.
Stage
II. The tumor at this stage may have grown larger than 2 inches, or it may
be a smaller tumor that involves nearby structures, such as the chest wall, the
diaphragm or the lining around the lungs (pleura). Cancer may also have spread
to the nearby lymph nodes.
Stage
III. The tumor at this stage may have grown very large and invaded other
organs near the lungs. Or this stage may indicate a smaller tumor accompanied
by cancer cells in lymph nodes farther away from the lungs.
Stage
IV. Cancer has spread beyond the affected lung to the other lung or to
distant areas of the body. Small cell lung cancer is sometimes described as
being limited or extensive. Limited indicates cancer is limited to one lung.
Extensive indicates cancer has spread beyond the one lung.
