Lung cancer is treated in our Thoracic Oncology Program (TOP) within the Upstate Cancer Center.
For more information or answers to your questions about our Cancer Care, please call 315 464-HOPE (4673) to speak with an Upstate Cancer Center representative.
Lung cancer is a disease in which cancer cells grow in the lungs. The most common type of lung cancer are:
- Non-small cell lung cancer—generally grows and spreads more slowly (most common)
- Small cell lung cancer—generally grows more quickly and is more likely to spread to other parts of the body

Cancer occurs when cells in the body divide without control or order. If cells keep dividing when new cells are not needed, a mass of tissue forms. This growth is called a tumor. Cancer growths can invade nearby tissue. It can then spread to other parts of the body. Regular damage increases the turnover of cells.
The following are known to damage to the lungs, and cause lung cancer:
- First- or second-hand smoke from cigarettes, cigars, or pipes
- Exposure to asbestos (a type of mineral) or radon (radioactive gas)
Things that may increase your chances of lung cancer are:
- Using chewing tobacco
- Exposure to second-hand smoke
- Exposure to asbestos or radon
- Having a lung disease, such as tuberculosis
- Family or personal history of lung cancer
- Exposure to certain air pollutants
- Exposure to coal dust
- Radiation therapy that was used to treat other cancers
- HIV infection
Most professional groups suggest lung cancer screening with a low-dose CT scan for those at high risk. High risk includes being 50 to 80 years old, history of heavy smoking, and being a current smoker or quit within last 15 years.
Symptoms and signs may include:
- A cough that does not go away and worsens over time
- Constant chest pain
- Coughing up blood
- Shortness of breath, wheezing, or hoarseness
- Repeated problems with pneumonia or bronchitis
- Swelling of the neck and face
- Loss of appetite or weight loss
- Clubbing—tips of fingers and toes become wider and rounder
The doctor will ask about symptoms and past health. A physical exam will be done. The doctor will also ask about:
- Smoking habits past or present
- Things you may have come in contact with that can harm lungs
- Family history of cancer
Tests may include:
- Sputum cytology—mucus from the lungs is sent to a lab
- Biopsy—a sample of lung tissue is removed and looked at under a microscope
Images of the lungs and chest may be taken with:
- Chest x-ray
- CT scan of chest
- PET scan
- PET/CT scan
- Bone scan
The doctor will use results from all tests to determine the stage of cancer. Staging is used to guide your treatment plan. Lung cancer is staged from 1 to 4. Stage 1 cancer is contained in a small area. Stage 4 caner is one that has spread to other parts of the body.
Lung cancer screening may help to find lung cancer at early stages in those at high risk.
The goal of treatment is to remove as much cancer as possible and control the symptoms.
Surgery is done to remove the tumor and nearby tissue. Lymph nodes may also need to be removed. The type of surgery depends on the stage and area. Common choices include:
- Segmental or wedge resection—a small part of the lung is removed
- Lobectomy—an entire lobe of the lung is removed
- Pneumonectomy—an entire lung is removed
Radiation therapy may be part of treatment. Radiation can kill cancer cells and shrink tumors. The therapy may also be used to relieve symptoms such as shortness of breath. External radiation is usually used to treat lung cancer. Radiation is directed at the tumor from a source outside of the body.
Chemotherapy is the use of drugs to kill cancer cells. This may be given as pills, injections, or through a catheter. Chemotherapy is often used to kill lung cancer cells that have spread to other parts of the body.
Researchers continue to study ways to treat lung cancer. The National Cancer Institute considers these potential therapies:
- Photodynamic therapy (PDT)—A chemical is injected into the bloodstream. It lingers in cancer cells longer than normal ones. A laser aimed at the cancer activates the chemical. This chemical then kills the cancer cells that have absorbed it. This treatment may also be used to reduce symptoms.
- Cryosurgery—A treatment that freezes and destroys cancer tissue.
Other treatments that are being researched include:
- Targeted therapy—medicine or substances target parts of the cancer cells.
- Immunotherapy—medicine or substances increase or restore the body's natural defenses against cancer.
To help reduce your chances of lung cancer:
- Do not start smoking. If you smoke, talk to your doctor about how to successfully quit.
- Avoid places where people are smoking.
- Test your home for radon gases and asbestos. Have these substances removed if they are in the home.
- Try to avoid or limit occupational exposures.

For more information:
- Non-Small Cell Lung Cancer
This is the most common type of lung cancer. About 85% of lung cancers are non-small cell lung cancers. Squamous cell carcinoma, adenocarcinoma, and large cell carcinoma are all subtypes of non-small cell lung cancer. See the American Cancer Society's Non-Small Cell Lung Cancer Guide for detailed information.
- Small Cell Lung Cancer
Small cell lung cancer is also called oat cell cancer. About 10%-15% of lung cancers are small cell lung cancers. This type of lung cancer tends to spread quickly. See the American Cancer Society's Small Cell Lung Cancer Guide for detailed information.
- Lung Carcinoid Tumor
Fewer than 5% of lung cancers are lung carcinoid tumors. They are also sometimes called lung neuroendocrine tumors. Most of these tumors grow slowly and rarely spread. See the American Cancer Society's Lung Carcinoid Tumor Guide for detailed information.
