Lung cancer is a type of cancer that starts in the lungs. Cancer starts when cells in the body begin to grow out of control.

Lung cancers typically start in the cells lining the bronchi and parts of the lung such as the bronchioles or alveoli.

Types of lung cancer

There are 2 main types of lung cancer and they are treated very differently.

Non-small cell lung cancer (NSCLC)[/cmsmasters_heading][cmsmasters_text shortcode_id=”vdfkyliryr” animation_delay=”0″]

About 80% to 85% of lung cancers are NSCLC. The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. These subtypes, which start from different types of lung cells are grouped together as NSCLC because their treatment and prognoses (outlook) are often similar.

Adenocarcinoma: [/cmsmasters_heading][cmsmasters_text shortcode_id=”snsm5p090i” animation_delay=”0″]

Adenocarcinomas start in the cells that would normally secrete substances such as mucus.

This type of lung cancer occurs mainly in people who currently smoke or formerly smoked, but it is also the most common type of lung cancer seen in people who don’t smoke. It is more common in women than in men, and it is more likely to occur in younger people than other types of lung cancer.

Adenocarcinoma is usually found in the outer parts of the lung and is more likely to be found before it has spread.

Squamous cell carcinoma: [/cmsmasters_heading][cmsmasters_text shortcode_id=”6qd7g2099k” animation_delay=”0″]

Squamous cell carcinomas start in squamous cells, which are flat cells that line the inside of the airways in the lungs. They are often linked to a history of smoking and tend to be found in the central part of the lungs, near a main airway (bronchus).

Large cell (undifferentiated) carcinoma: [/cmsmasters_heading][cmsmasters_text shortcode_id=”b0lfkj3oai” animation_delay=”0″]

Large cell carcinoma can appear in any part of the lung. It tends to grow and spread quickly, which can make it harder to treat. A subtype of large cell carcinoma, known as large cell neuroendocrine carcinoma, is a fast-growing cancer that is very similar to small cell lung cancer.

A few other subtypes of NSCLC, such as adenosquamous carcinoma and sarcomatoid carcinoma, are much less common.

Small cell lung cancer (SCLC)[/cmsmasters_heading][cmsmasters_text shortcode_id=”jlyuj4h4p” animation_delay=”0″]

About 10% to 15% of all lung cancers are SCLC and it is sometimes called oat cell cancer. This type of lung cancer tends to grow and spread faster than NSCLC. About 70% of people with SCLC will have cancer that has already spread at the time they are diagnosed. Since this cancer grows quickly, it tends to respond well to chemotherapy and radiation therapy.

Cancers that start in other organs (such as the breast, pancreas, kidney, or skin) can sometimes spread (metastasize) to the lungs, but these are not lung cancers. For example, cancer that starts in the breast and spreads to the lungs is still breast cancer, not lung cancer. Treatment for metastatic cancer to the lungs is based on where it started (the primary cancer site).

The best way to reduce your risk of lung cancer is not to smoke and to avoid breathing in other people’s smoke. If you stop smoking before a cancer develops, your damaged lung tissue gradually starts to repair itself. No matter what your age or how long you’ve smoked, quitting may lower your risk of lung cancer and help you live longer.

A healthy diet with lots of fruits and vegetables may also help reduce your risk of lung cancer. Some evidence suggests that a diet high in fruits and vegetables may help protect people who smoke and those who don’t against lung cancer. But any positive effect of fruits and vegetables on lung cancer risk would be much less than the increased risk from smoking.
