Part 7: Treatment by cancer stage
7.1 Stage I treatments
You may have stage I lung cancer based on tests given
before treatment. In stage IA, the lung tumor is 3 cm or
smaller. A stage IB tumor can be as large as 5 cm or may
have grown into the main airway or tissue lining of the lung.
The chart above maps the treatment options for stage I.
Which primary treatment you will have depends on if you
are able to have surgery. If lung surgery is an option,
removal of the tumor and lymph nodes is recommended.
The goal of surgery is to cure the cancer.
During surgery, your doctors may find more cancer than
first thought. This may change the stage of the cancer. If the
cancer is upstaged, go back to page 55 to find out which
pages to read for adjuvant treatment.
If the cancer remains stage I, you may receive adjuvant
treatment depending on the surgical results. Treatment
options differ whether the cancer is stage IA or IB. Cancer in
the surgical margin also affects treatment options.
