Non-Small Cell Lung Cancer:
This is the more common type of lung cancer.
"About 85% to 90% of lung cancers are non-small cell lung cancer (NSCLC). There are 3 main subtypes of NSCLC. The cells in these subtypes differ in size, shape, and chemical make-up when looked at under a microscope. But they are grouped together because the approach to treatment and prognosis (outlook) are very similar.
Squamous cell (epidermoid) carcinoma: About 25% to 30% of all lung cancers are squamous cell carcinomas. These cancers start in early versions of 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 middle of the lungs, near a bronchus.
Adenocarcinoma: About 40% of lung cancers are adenocarcinomas. These cancers start in early versions of the cells that would normally secrete substances such as mucus. This type of lung cancer occurs mainly in people who smoke (or have smoked), but it is also the most common type of lung cancer seen in non-smokers. 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 region of the lung. It tends to grow slower than other types of lung cancer, and is more likely to be found before it has spread outside of the lung. People with the type of adenocarcinoma calledadenocarcinoma in situ (previously called bronchioloalveolar carcinoma) tend to have a better outlook (prognosis) than those with other types of lung cancer.
Large cell (undifferentiated) carcinoma: This type of cancer accounts for about 10% to 15% of lung cancers. It may 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 (see below).
Other subtypes: There are also a few other subtypes of non-small cell lung cancer, such as adenosquamous carcinoma and sarcomatoid carcinoma. These are much less common."
SCLC often starts in the bronchi near the center of the chest, and it tends to spread widely through the body fairly early in the course of the disease."

Lung cancer is the second most common cancer among men and women. It is also the leading cause of cancer death in men and women. It far surpasses breast, prostate, and colon cancers. One of the most common causes of lung cancer is smoking and other tobacco use. Lung cancer can also be caused from radon or asbestos, which are found in mines and textile plants.

Lung cancer cannot be fully prevented, but there are things you can do to reduce your risk. The first is obvious, don't smoke! If you do, QUIT! There are many places that can help one to quit smoking. The American Cancer Society provides a guide of how to quit and gives you a phone number to call for help. You can also visit smokefree.gov for assistance and guidance.
As I said before, Radon is a cause of lung cancer. The best way to prevent exposure to Radon is to have your home tested.
Studies have shown that eating a diet of fruits and vegetables will decrease your chance of getting lung cancer.

| Here, not so much |
As always, scanning for any type of cancer plays a large role in early detection. You can also have a CT scan done which has been shown to catch lung cancer more often. Make sure you tell your loved ones to get tested for all types of cancers, and MAKE THEM QUIT SMOKING! Its extremely harmful to your body, and it is gross!! Look at this disgusting list of the active ingredients in cigarettes. Notice Urea? Yeah, that's found in urine. Think about that the next time you go to light up.
