Targeted therapy or immunotherapy drugs are used to treat non-small cell lung cancer that has spread outside the lung or to other parts of the body.
Your doctor does tests on the cancer cells called molecular testing. These tests help find out if some of these drugs are suitable options for you. The doctor does the tests on the tissue they take during a biopsy or surgery, or occasionally on a blood test.
The drugs can cause different side effects. Your doctor or nurse will talk to you about this. Always tell them about any side effects you have. They will explain how you can manage them. There are also often things they can do to improve your side effects.
Your doctor might talk to you about having some of these drugs as part of a clinical trial. Newer targeted and immunotherapy drugs are being developed and becoming available.
