What is non-small cell lung cancer?

Non-small cell lung cancer is 1 type of lung cancer. Lung cancer happens when normal lung cells change into abnormal cells and grow out of control. There are different types of lung cancer. Some types grow faster than others.

Non-small cell lung cancer is the most common type of lung cancer. It does not usually grow as fast as another type of lung cancer called small cell lung cancer.

What is lung cancer staging?

Cancer staging is a way in which doctors find out how far in your body a cancer has spread. To describe how far a person's non-small cell lung cancer has spread, doctors call it stage 1, 2, 3, or 4. These are also written as stage I, II, III, or IV.

Sometimes, staging can be tricky. For example, your doctor might think that you have stage 1 or stage 2 cancer. But after you have surgery, your doctor might check the tissues you had removed and discover that you really have stage 3 cancer.

Here are some of the main differences between the stages:

In stage 1, the lung cancer is in either the left or right lung. It has not spread outside of the lung or to any lymph nodes. (Lymph nodes are bean-shaped organs that are part of the body's infection-fighting system.) Stage 1 cancers are usually small.
In stage 2, the cancer has spread to other parts of the lung, such as lymph nodes in the lung or the lining around the lung. Stage 2 cancers can be different sizes.
In stage 3, the cancer might be large. Or it might have spread to lymph nodes in the middle of the chest, between the left and right lungs.
In stage 4, the cancer has spread to the other lung or to other parts of the body, such as the brain or bones. Also, lung cancer is described as stage 4 if it causes fluid to collect around the outside of the lungs.

Your treatment will depend a lot on the stage of your lung cancer.

How are stage 1 and stage 2 non-small cell lung cancers treated?

People with stage 1 or stage 2 non-small cell lung cancer are usually first treated with surgery to remove the cancer. To remove the cancer, a doctor might remove part of a lung. Or they might need to remove the whole lung. (People who have 1 lung removed can use their other lung to breathe.)

People with stage 1 lung cancer might not need any other treatment after surgery. But people with stage 2 lung cancer usually need more treatment after surgery. This can include:

Radiation therapy – Radiation kills cancer cells. Some people who do not want surgery or who cannot have surgery have radiation therapy instead.
Chemotherapy – Chemotherapy is the medical term for medicines that kill cancer cells or stop them from growing.
Other treatments – Depending on the characteristics of your cancer, you might get other treatments. One example is immunotherapy, which means medicines that work with the body's infection-fighting system to stop cancer growth. Another is targeted therapy, which means medicines that work for cancers with certain characteristics. Your doctor might do tests to find out if these treatments might work for your cancer.

Sometimes, people with stage 1 or stage 2 cancer are treated with radiation therapy rather than surgery. This might be the case if they have other problems that prevent them from having surgery.

How is stage 3 non-small cell lung cancer treated?

Doctors can treat stage 3 non-small cell lung cancer in different ways. Treatment depends on where the cancer is, how big it is, and which treatments a person has already had.

People with stage 3 lung cancer usually have 1 or more of the following treatments:

Chemotherapy
Radiation
Immunotherapy
Surgery

Doctors also treat another type of lung cancer, called a "Pancoast tumor," using some of these treatments. A Pancoast tumor is a lung cancer that grows in the top part of the lung.
