The lining around the lungs, called the pleura, helps to protect the lungs and allows them to move during breathing. The windpipe (trachea) brings air down into the lungs. It divides into tubes called bronchi, which divide into smaller branches called bronchioles. At the end of these small branches are tiny air sacs known as alveoli.

Most lung cancers start in the lining of the bronchi but they can also begin in other areas such as the trachea, bronchioles, or alveoli. Lung cancer often takes many years to develop. Once the lung cancer occurs, cancer cells can break away and spread to other parts of the body. Lung cancer is a life-threatening disease because it often spreads in this way before it is found.

Imaging tests: these tests use x-rays, magnetic

Stage II: As in stage I NSCLC, most patients with stage II NSCLC have their cancer surgically removed by lobectomy or by some less extensive surgery such as a segmentectomy or wedge resection for those people who cannot withstand lobectomy.

Small cell lung cancer accounts for about 20% of all lung cancers. Although the cancer cells are small, they can multiply quickly and form large tumors. The tumors can spread to the lymph nodes and to other organs such as the brain, the liver, and the bones. Small cell lung cancer is usually caused by smoking. Other names for small cell lung cancer are oat cell cancer and small cell undifferentiated carcinoma.

Radiation therapy alone can be used for patients who cannot undergo surgery due to other serious health problems.

After looking at your test results, the doctor will tell you the stage of your cancer. Be sure to ask your doctor to explain your stage in a way you understand. This will help you both decide on the best treatment for you.

Side effects of radiation therapy may include mild skin problems, nausea, vomiting, and fatigue. Often these go away after a short while. Radiation may also make the side effects of chemotherapy worse. Chest radiation therapy may cause lung damage and lead to difficulty breathing and shortness of breath. The swallowing tube (esophagus) runs through the middle of the chest and will be exposed to radiation. For this reason, there will also be difficulty with swallowing during the treatment, which improves shortly after it is over. Radiation therapy to large areas of the brain can sometimes result in significant changes in brain function. Symptoms may include memory loss, headache, difficulty thinking, or diminished sexual desire. Usually these symptoms are minor compared to those caused by a brain tumor; nevertheless, they can impact negatively on the patient's quality of life. Side effects of radiation therapy to the brain usually become most serious one or two years after.
