-most lung cancer starts in the lining of the bronchi -it often takes many years to develope -pre-cencerous changes in the lung do not show up on x-rays, and they don't have symptoms -the cancer makes chemicals that cause new blood vessels to form nearby -the new blood vessels allow a tumor to form -the tumor eventually becomes large enough to be seen on an x-ray -the cancer cells can break away and spread to other parts of the body -lung cancer is a life-threatening disease because it often spreads before it's found -lung cancer cells can enter the lymph system and grow

 **Types of Lung Cancer** -small cell lung cancer -non-small cell lung cancer

 **Non-Small Cell Lung Cancer** -about 8 to 9 out of 10 cases of lung cancer are the non-small cell type -there are 3 sub-types of non-small cell lung cancer 1. Squamous cell carcinoma: 25%-30% of lung cancers are this kind. They are linked to smoking and are found near a bronchus. 2. Adenocarcinoma: 40% of lung cancers are this type. It is usually found near the outer part of the lung. 3. Large-cell (undifferentiated) carcinoma: 10%-15% of lung cancers are this type. It can start in any part of the lung, and grows and spreads quickly. This makes it harder to treat.  -about 10%-15% of lung cancers are this type -often starts in the bronchi near the center of the chest -these cells can mulitply quickly and form large tumors that spread throughout the body -surgery is rarely an option -treatment must include drugs to kill widespread diseases -almost always caused by smoking

 1. One point that I learned on your page that I did not know before was: That people dont have symtomes to lung cancer and it doesnt show up on an X-Ray. 2. The page you created was informative or interesting because: I wasnt educated on lung cancer before i read this article, 3. How I can use this information in my life now or in the future is: to learn more about it just in case someone I know or myself get lung cancer. 4. I would still like to know more about: how to prevent lung cancer and the statistics. A.R.

The page you created was informative or interesting because: it has different colors and i didn't know much about lung cancer before this 3. How I can use this information in my life now or in the future is... to hlep educate people in the future that might be at risk for lung cancer 4. I would still like to know more about... how to treat and prevent lung cancer......JM
