 * Lung cancer is the uncontrolled cell growth of tissue in the lungs.
 * Normally, the body maintains a system of checks and balances on cell growth so that cells divide to produce new cells only when needed.
 * When this is disrupted, it leads to uncontrollable cell growth, which leads to the build up of tumors.
 * Lung cancer is responsible for the most cancer deaths in men and women
 * The American Cancer Society estimates that 213,380 new cases of lung cancer in the U.S. will be diagnosed and 160,390 deaths due to lung cancer will occur.
 * Lung cancer mostly occurs in the elderly
 * Almost 70% of people who get lung cancer are over the age of 65
 * Less than 3% are under the age of 45
 * Causes of cancer?
 * 1) **Smoking**
 * 2) [[image:15smoking.span.jpg width="416" height="241"]]
 * 3) About 90%of lung cancer comes from the use of tobacco
 * 4) Tobacco smoke contains over 4,000 chemical compounds, many of which have been shown to be cancer-causing, or carcinogenic.
 * 5) Two primary carcinogens in tobacco smoke are chemicals known as nitrosamines and polycyclic aromatic hydrocarbons.
 * 6) **Passive** **Smoking**
 * 7) Inhalation of tobacco smoke is a risk of development of lung cancer
 * 8) **Air Pollution**
 * 9) Air pollution from vehicles, industry, and power plants can raise the likelihood of developing lung cancer in exposed individuals
 * 10) Up to 1% of lung cancer cases are from air pollution
 * There are two types of Lung Cancer
 * 1) **Small cell lung cancers (SCLC)**
 * 2) Accounts for 20% of lung cancer cases.
 * 3) SCLC are strongly related to cigarette smoking, with only 1% of these tumors occurring in nonsmokers.
 * 4) **Non-small cell lung cancers (NSCLC)**
 * 5) Most common lung cancer, accounting for about 80% of all lung cancers.
 * Symptoms
 * 25% of people find out they have lung cancer from x-rays
 * Difficulty breathing
 * coughing
 * wheezing
 * coughing up blood
 * chest pain
 * [[image:i226__Lung2.JPG width="475" height="300"]]
 * Treatment
 * Surgical removal of the tumor
 * About 10-35% of tumors can be removed surgically
 * Depends on the size and the location of the tumor
 * Chemotherapy
 * Chemotherapy refers to the administration of drugs that stop the growth of cancer cells by killing them or preventing them from dividing
 * Radiation Therapy
 * Radiation therapy uses high-energy x-rays or other types of radiation to kill dividing cancer cells
 * How can lung cancer be prevented?
 * Avoiding cigarette smoke and smoking cigarettes is the number one prevention of lung cancer.

Script:
Sorry for interrupting your show, but, this is a public service announcement brought to you by Dr.Field's Human bio class, the events and suggestions are not to be taken lightly in this podcast.

Lung cancer, it is responsible for the most cancer deaths in men in women. The American Cancer society estimates that 213,380 new cases of lung cancer in the US will be diagnosed and 160,390 deaths due to lung cancer will occur.

Lung cancer is the uncontrolled cell growth of tissue in the lungs, which leads to tumors. Normally, the body maintains a system of checks and balances on cell growth so that cells produce new cells when needed.

You may ask yourself, what causes lung cancer? Smoking is the number one cause. about 90% of lung cancer comes from the use of tobacco. Passive smoking, such as inhalation of cigarette smoke is another cause as well. Polluted air that is growing ever so rapidly can also lead to lung cancer.

You may wonder if you have this deadly cancer. Symptoms include difficulty breathing, coughing, wheezing, coughing up blood, or chest pain. If any of these occur, please contain you doctor for a check up. To treat lung cancer you can either have surgery to remove the tumor, if the location and size are okay, chemotherapy, or radiation therapy. To prevent yourself from this cancer, avoid cigarette smoke and smoking tobacco products.

Remember, friends don't let friends smoke to later develop lung cancer. Now back to your show.
