Lung Cancer- Pavan

Why Did I Choose This Topic?

I chose this topic because I felt that many people are aware of lung cancer but don’t really know it affects them. It is a very difficult disease to cure and very hard to prevent from spreading. Lung cancer happens to be the most common cancer in the world.

About Lung Cancer:

Lung cancer originates in the lungs, but can spread to other parts of the body. Cancer that begins elsewhere but spreads to the lungs is not lung cancer.According to the U.S Centers For Disease Control (CDC), lung cancer is the second most diagnosed cancer in the United States. Nonsmokers can get lung cancer too, but smoking is the leading cause. In the past few decades, the rate of lung cancer has fallen at about the same rate as cigarette smoking.

Who Gets It and Why?

Anyone can get lung cancer, but certain factors put you at greater risk. Smoking is the number one risk factor. You are also at increased risk if you have a family history of lung cancer, especially a parent or sibling.Other dangers include exposure to secondhand smoke, radon gas, or asbestos. Substances like arsenic, nickel, and chromium can also pose a risk

Relevancy To Teens?

Many teenagers are beginning to smoke now due to various reasons. One of the main ones is peer pressure. Teenage is a delicate phase, and it’s easier to give in to temptations and peer pressure, especially about smoking. Thus it is important to always be strong with your decision and avoid going towards poeple who smoke.

Why Do The Lungs Look Black?

As you can see in the picture below  the smoker’s lungs look dark and blackish. The reason for this is Under the microscope, with this high magnification, you can actually see the black and brown engulfed particles in the alveolar scavenger cells. These scavenger cells are engulfed with  particles of impurities and debris. Each time the smoker was inhaling the chemicals they were getting gathered up in the scavenger cells

Cures?

There are 3 main cures for lung cancer, surgery, chemotherapy, and radiotherapy. You may have an operation to remove the tumor and the surrounding tissue. This may mean that the surgeon may remove a part of the lower lung, or the whole lung. Radio therapy is is therapy using ionizing radiation, generally as part of cancer treatment to control or kill malignant cells. Chemotherapy is the use of anti-cancer drugs to destroy cancer cells, and most of it is through injections or drips.

Symptoms:

People with early stage lung cancer are often unaware that anything is wrong. As the cancer grows, a chronic cough may develop. Smokers may notice a change in their “smoker’s cough” or may start coughing up blood. Many patients report hoarseness, wheezing, and frequent shortness of breath. You may also experience chest pain, bone pain, or headache.

What Did I Learn?

I learned several things whilst researching on this topic. One of the main things was why the lungs itself  becomes very black and dark. I also had the oppurtunity in class to actually see a mini model on how a smoker’s lungs looked like and that helped me get a better understanding on the cancer cells, and the lungs itself. I also became more aware of other types of cancer which is also very deadly and dangerous. Lung cancer made me become more aware of this situation and I was able to understand how dangerous it is to breathe into these hazardous chemicals.

How to Help Prevent Lung Cancer:

Dont Smoke. If you never smoked then don’t start. Talk to your children and friends about it so that they will also be more aware of this situation.

Avoid secondhand smoke. If you live or work with a smoker, urge him or her to quit. At the very least, ask him or her to smoke outside. If you walk into a group in which people are smoking just cover your mouth and nose and walk past them quickly.

Test your home for radon. Have the radon levels in your home checked, especially if you live in an area where radon is known to be a problem. High radon levels can be remedied to make your home safer.

Eat a diet full of fruits and vegetables. Choose a healthy diet with a variety of fruits and vegetables. Food sources of vitamins and nutrients are best. Avoid taking large doses of vitamins in pill form, as they may be harmful. For instance, researchers hoping to reduce the risk of lung cancer in heavy smokers gave them beta carotene supplements.
