Description

Lung cancer is a type of cancer that begins in the lungs. Your lungs are two spongy organs in your chest that take in oxygen when you inhale and release carbon dioxide when you exhale.

Lung cancer is the leading cause of cancer deaths worldwide.

People who smoke have the greatest risk of lung cancer, though lung cancer can also occur in people who have never smoked. The risk of lung cancer increases with the length of time and number of cigarettes you've smoked. If you quit smoking, even after smoking for many years, you can significantly reduce your chances of developing lung cancer.

Symptoms

Lung cancer typically doesn't cause signs and symptoms in its earliest stages. Signs and symptoms of lung cancer typically occur when the disease is advanced.

Signs and symptoms of lung cancer may include:

·        A new cough that doesn't go away

·        Coughing up blood, even a small amount

·        Shortness of breath

·        Chest pain

·        Hoarseness

·        Losing weight without trying

·        Bone pain

·        Headache

When to see a doctor

Make an appointment with your doctor if you have any persistent signs or symptoms that worry you.

If you smoke and have been unable to quit, make an appointment with your doctor. Your doctor can recommend strategies for quitting smoking, such as counseling, medications and nicotine replacement products.

Causes

Smoking causes the majority of lung cancers — both in smokers and in people exposed to secondhand smoke. But lung cancer also occurs in people who never smoked and in those who never had prolonged exposure to secondhand smoke. In these cases, there may be no clear cause of lung cancer.

How smoking causes lung cancer

Doctors believe smoking causes lung cancer by damaging the cells that line the lungs. When you inhale cigarette smoke, which is full of cancer-causing substances (carcinogens), changes in the lung tissue begin almost immediately.

At first your body may be able to repair this damage. But with each repeated exposure, normal cells that line your lungs are increasingly damaged. Over time, the damage causes cells to act abnormally and eventually cancer may develop.

Types of lung cancer

Doctors divide lung cancer into two major types based on the appearance of lung cancer cells under the microscope. Your doctor makes treatment decisions based on which major type of lung cancer you have.

The two general types of lung cancer include:

·        Small cell lung cancer. Small cell lung cancer occurs almost exclusively in heavy smokers and is less common than non-small cell lung cancer.

·        Non-small cell lung cancer. Non-small cell lung cancer is an umbrella term for several types of lung cancers. Non-small cell lung cancers include squamous cell carcinoma, adenocarcinoma and large cell carcinoma.

Risk factors

A number of factors may increase your risk of lung cancer. Some risk factors can be controlled, for instance, by quitting smoking. And other factors can't be controlled, such as your family history.

Risk factors for lung cancer include:

·        Smoking. Your risk of lung cancer increases with the number of cigarettes you smoke each day and the number of years you have smoked. Quitting at any age can significantly lower your risk of developing lung cancer.

·        Exposure to secondhand smoke. Even if you don't smoke, your risk of lung cancer increases if you're exposed to secondhand smoke.

·        Previous radiation therapy. If you've undergone radiation therapy to the chest for another type of cancer, you may have an increased risk of developing lung cancer.

·        Exposure to radon gas. Radon is produced by the natural breakdown of uranium in soil, rock and water that eventually becomes part of the air you breathe. Unsafe levels of radon can accumulate in any building, including homes.

·        Exposure to asbestos and other carcinogens. Workplace exposure to asbestos and other substances known to cause cancer — such as arsenic, chromium and nickel — can increase your risk of developing lung cancer, especially if you're a smoker.

·        Family history of lung cancer. People with a parent, sibling or child with lung cancer have an increased risk of the disease.

    Overcoming Challenges

    So, what is a challenge? A challenge is something new and complex that requires great effort and determination. It's not bad to be challenged in relationships, work, and life. When we are forced to think differently, we can tap into resources we may not have known existed before. I remember someone saying you never know your strength until you have to use it. I believe in that statement wholeheartedly.

    How to Face Challenges with Purpose

    Life is challenging at times. Even during times of struggle it is possible to be on purpose.What I have discovered is there are four important areas to consider when dealing with setbacks in life. These important considerations will help you as you focus your energy on improving in any area of life.The Importance of PurposeTo be on purpose requires you to answer the question, “Why am I here?” The success of your personal endeavors will rise and fall on the compelling why behind the what. When we choose not to answer this question out loud, we leave the door open for excuses. We become susceptible to our circumstances when the why is poorly defined, or worse, missing completely. Being purposeful is directional. Answering the why provides a direction for my life, which is important to know when facing challenges.The Importance of ClarityConfusion prevents movement, clarity provides a clear path. The importance of clarity has three basic ideas:

    Life Is Complicated, and That Is Good

    If you have ever thought that life is just getting too complicated, you may well be right. Life can indeed be too complicated. There is evidence that today many aspects of the way we live are over that limit, and it is this that explains many of the problems we face and the everyday irritations we encounter. This is not a simple matter of markets versus politics or public as opposed to private. Certainly government is the source of much of the excessive complexity, most notably through its regulative function, but much of it has purely private origins. Excessive complexity is found as much in business and its practices as in regulations and laws put out by the state.
