Lung Cancer: Frequently Asked Questions
What is lung cancer?
Cancer is a disease in which certain body cells don't function right, divide very fast, and produce too much tissue that forms a tumor. The lungs, a pair of sponge-like, cone-shaped organs, are part of the body's respiratory system. When we breathe in, the lungs take in oxygen, which our cells need to live and carry out their normal functions. When we breathe out, the lungs get rid of carbon dioxide, which is a waste product of the body's cells. ...

Lung cancer is the most frequently occurring cancer in the US, accounting for 30% of all diagnosed cancer. The largest number of asbestos related deaths occurs from lung cancer. Most lung cancer caused by asbestos inhalation starts in the lining of the bronchi, the tubes that lead from the windpipe into each lung. Lung cancer caused by asbestos exposure can also begin in the windpipe itself, the bronchioles, smaller tubes which branch off from the bronchi, or in the alveoli. ...

Cancer is a group of diseases caused by rapidly dividing cells. As these cell divide they change and can no longer do the job they were intended. Lung cancer is a disease that begins in the cells of the lungs. It is currently believed that lung cancer may slowly develop over ten or more years before it seen on x-ray or some other radiological scan. However, lung cancer can spread quickly to other parts of the body, because it starts out in an organ through which the blood in the body flows through. ...

Lung cancer is cancer that begins in the lungs. It is the second most common cancer in women. There are two major types of lung cancer: small cell lung cancer and non-small cell lung cancer. Approximately 80 percent of people with lung cancer have non-small cell cancer, while 20 percent have small cell lung cancer. The earlier that lung cancer is detected, the better the chance it will be cured. It is difficult, however, to detect lung cancer in its early stages. ...

What are the symptoms of lung cancer?
Because the symptoms of lung cancer are somewhat vague, people with lung cancer often confuse their symptoms with those of other problems and fail to visit their physician. If these symptoms have affected you, please visit your doctor: A "smoker's cough" Chest pain Sudden weight loss Fatigue, weariness or shortness of breath Blood in phlegm Pneumonia or bronchitis Facial swelling

In its early stages, there are often no symptoms of lung cancer. It is, however, often detected while doing other screenings (such as a chest x-ray for a rib injury). Once the disease progresses there are many symptoms that should not be ignored. These symptoms include a persistent cough, coughing up blood, chest pains that will not go away, and significant

What are the causes of lung cancer?
The leading cause of lung cancer is smoking cigarettes. Approximately 85 percent of all patients diagnosed with lung cancer are current or former smokers. Those who smoke cigars, pipes, or marijuana cigarettes run an even greater risk of developing lung cancer because there is no filter to protect their lungs. Secondhand smoke, radon, pollution, and asbestos exposure are also causes of lung cancer.

The American Cancer Sociaty estimates that smoking causes 87 percent of lung cancers. Harmful substances called carcinogens in tobacco harm cells in the lungs. After a while, these cells may turn into cancer. The longer a person smokes, and the more a person smokes, the higher the risk of lung cancer.

How is lung cancer diagnosed?
If a patient exhibits symptoms of lung cancer, a diagnosis of lung cancer is of the utmost importance to ensure effective treatment. A physician will usually review a patient's health history, take a chest x-ray, and perform an analysis of a sputum sample. Final analysis, however, is based on a tissue or fluid sample taken from the lungs. If it has been determined that a patient has lung cancer, further studies will be made to determine what type of cancer the patient has and if it has spread.

Lung cancers are sometimes first detected on routine chest X-rays. However, the main method of diagnosis is bronchoscopy, in which a thin, flexible tube is inserted down the airways (under anaesthetic), allowing doctors to see the inside of the lungs and even take a biopsy (a sample small of the suspect tissue). A CT scan, liver ultrasound or bone scan may also be used to find out if the cancer has spread.

How is lung cancer detected?
The symptoms of lung cancer only appear in a late stage. These are persistent cough, blood in sputum, chest pain etc. The most prominent method for detecting lung cancer is by routine chest x-rays. Sputum examination may also reveal a lung cancer. It is to be noted that a lung cancer detected is never an early cancer. Even with the best methods of treatment, whether it is surgery, radiation or chemotherapy the survival rate is very poor. ...

Who Is At High Risk For Lung Cancer?
You are at high risk for lung cancer if you are or were a smoker with the equivalent of a 10 "pack-year" history, and you are age 50 or above. To calculate your personal "pack-year" history, multiply the number of years you have smoked by the number of packs per day. (For example, if you smoked 2 packs per day for 5 years, you have a 10 "pack-year" history. ) If you have a "pack-year" history of 10 or more, you should strongly consider annual chest CT screening as you are at high risk for lung cancer.

What is happening with incidence rates for lung cancer?
Overall, lung cancer incidence rates increased in women from 1975-2003, though the rate of increase slowed over time. In particular, this year's report suggests a small increase in female lung cancer incidence rate from 1991-2003. The increase observed during this period represents a change from last year's annual report, where rates appeared stable. From 1995-2003, rates were increasing in women 65 years and older, decreasing among women ages 45-64 years old, and stable in women younger than 45 years old. ...

What is the difference between lung cancer and mesothelioma?
Mesothelioma is not a form of lung cancer because it attacks the lining of the lung (pleura) and not the lung tissue directly. Smoking is usually the major cause of lung cancer but smoking cannot cause mesothelioma.

What is non-small cell lung cancer?
Non-small cell lung cancer , or "non-small cell carcinoma," includes squamous cell carcinoma , large cell carcinoma , and adenocarcinoma . Squamous cell carcinoma develops in non-glandular lung tissue and spreads less quickly than other forms of lung cancer. Large cell carcinoma is often found in the smaller bronchi and is recognized by the large masses or tumors that it forms. Adenocarcinoma is a glandular form of lung cancer with low patient survival odds.

What is small-cell lung cancer?
Small-cell lung cancer , often referred to as oat cell lung cancer, is particularly dangerous to patients because it spreads quickly or "metastasizes" to other parts of the body. Small-cell lung cancer usually originates in the lung's hormone cells.

Can pollution cause lung cancer?
Air pollution has been shown to contribute to the likelihood that a person will develop lung cancer. Carcinogens in the air, particularly nitrogen oxide, cause steady damage to the lungs over time. The effects of air pollution are particularly dangerous when compounded by other risk factors such as smoking.

What treatments are available for lung cancer patients?
Treatments options for lung cancer include lung cancer surgery , radiation therapy , chemotherapy , immunotherapy, radioimmunotherapy, and photodynamic therapy . A doctor will consider a patient's overall health, the form of the cancer, and the extent to which it has metastasized before deciding on a treatment strategy.

How can lung cancer be prevented?
Because most lung cancer occurs as a result of smoking, not smoking is the greatest preventative measure a person can take. Within 15 years of smoking cessation, a person who smoked for years can significantly reduce his or her risk of developing lung cancer. Here are some further preventative measures you can take to prevent lung cancer: Make sure that radon (a radioactive gas) is not present in your home Wear a protective mask if you will be working around products that could contain asbestos Avoid situations where you will be exposed to secondhand smoke

Why is lung cancer screening important?
Lung cancer results in more deaths in the United States than any other cancer; in fact, it accounts for more deaths than breast, cervix, colon, and prostate cancer combined. Because lung cancer has no symptoms in its early stages, more than 85 percent of the men and women who are diagnosed with lung cancer today are diagnosed in a late stage, after symptoms occur and when there is very little chance of cure. As a result, approximately 95% of the more than 200,000 people diagnosed each year die from the disease. ...
