The leading risk factor for lung cancer is smoking. More than 80% of lung cancers are due to cigarette smoking. The longer a person has been smoking and also the more cigarettes a person smokes a day, the greater the risk is for developing lung cancer. Not only are smokers vulnerable to lung cancer, but the people around them are at a greater risk as well due to breathing second-hand smoke. Non-smokers who are married to smokers are at a 30% greater risk than non-smokers who are married to non-smokers. Marijuana cigarettes may also increase the risk of lung cancer since they contain many of the same cancer-causing agents that tobacco cigarettes have and are inhaled more deeply.

Lung cancer most commonly begins in the cells that line your lungs. 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. In these cases, there may be no clear cause of lung cancer. Doctors have identified factors that may increase the risk.

Lung cancer is one of the most common cancers in the world. It is a leading cause of cancer death in men and women in the United States. Cigarette smoking causes most lung cancers. The more cigarettes you smoke per day and the earlier you started smoking, the greater your risk of lung cancer. High levels of pollution, radiation and asbestos exposure may also increase risk.

Causes of Lung Cancer

Smoking: smoking remains the greatest risk factor for lung cancer. 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.

Diet: Scientists are studying many different foods to see how they may change the risk of getting lung cancer. However, any effect diet may have on lung cancer risk is small compared with the risk from smoking. Eating a lot of fat and cholesterol might increase risk of lung cancer. Drinking a lot of alcohol may raise risk as well.

Family History: Studies have found a chromosome that may be resposible for lung cancer. The chromosome can be inherited. If you have had lung cancer before, there is a chance you may develop another type of lung cancer.

Air pollution from vehicles, industry, and power plants can raise the likelihood of developing lung cancer in exposed individuals. Up to 1% of lung cancer deaths are attributable to breathing polluted air, and experts believe that prolonged exposure to highly polluted air can carry a risk similar to that of passive smoking for the development of lung cancer.

Symptoms of Lung Cancer

People often decide to visit the doctor only after they have been bothered by certain complaints over a period of time. Individuals who have lung cancer frequently experience symptoms such as the following:

Metastasis to the bones is most common with small cell type cancers but also occurs with other lung cancer types. Lung cancer that has metastasized to the bone causes bone pain, usually in the backbone (vertebrae), the thighbones, and the ribs.

Shortness of breath usually results from a blockage to the flow of air in part of the lung, collection of fluid around the lung (pleural effusion), or the spread of tumor throughout the lungs.

A cough that does not go away or gets worse over time should be evaluated by a health-care provider.

Chest pain is a symptom in about one-fourth of people with lung cancer. The pain is dull, aching, and persistent and may involve other structures surrounding the lung.

Wheezing or hoarseness may signal blockage or inflammation in the lungs that may go along with cancer.

Cancer & Health – It’s All about The Cell

Lung cancer is a major killer of men and women across the country. Air pollutants, secondhand smoke, cigarette smoking especially, and other causative factors contribute to the disease.

Most of us think that the lung cancer is mostly common among the cigarette smokers and it is true that the vast majority of cases are or were smokers. But there are non-smokers do get lung cancer and smokers who don’t get it.

Signs of lung cancer are often not apparent in the early stages. However it is better to identify lung cancer as possible.

The most common early symptom of lung cancer is haemoptysis (coughing up blood). Consider this early symptom a warning sign of a cancer, which may be curable.

If you find that you are coughing up blood, you should immediately contact your doctor , especially if you are 40 years of age, or older, with a long-term smoking habit.

Some of the primary signs include:

* Hacking, persistent cough

* Coughing up blood

* Shortness of breath

* Wheezing

* Chest pain

* Lost appetite

* Lost weight

* Recurring bronchitis or pneumonia

The above symptoms also being the symptoms of many other lung problems, so it is always advisable to see a physician to ascertain the cause

Secondary signs of simple cell lung cancer include:

* Weakness

* Difficulty swallowing

* Changes in nails

* Hoarse or raspy voice

* High fever

* Swelling of facial features

It’s true that most symptoms of lung cancer do not show themselves until the disease is in its advanced stages.

However, sometimes people exhibit signs early in the disease’s development. It is imperative that the first notice of symptoms or concern sends you straight to the doctor.

The sooner treatment is begun, the better. A cure is possible if caught early enough and, if not, then a better quality of life and more of it.

When lung cancer spreads to other parts of the body, organs and bones, referred to as ‘metastasizing’, signs and symptoms include:

* Aching and sharp bone pain

* Changes in the brain that exhibit themselves through weakness, numbness, dizziness, and seizure

* Jaundice (whites of eyes, nails, and skin yellow

* Masses near the skin’s surface

* Headaches

* Numbness and loss of sensation in your extremities

All of these signs and symptoms of lung cancer may be caused by other health problems. The only way to know for sure is to consult a doctor as soon as possible.

As with most cancers, the earlier you detect lung cancer the better your chances of survival. In fact, when it’s caught in the first stages, there’s an almost 50% survival rate after five years. This is a remarkable number considering the fact that overall, lung cancer has only a 15% survival rate.

So the earlier it’s diagnosed the better.

And that’s why being aware of the signs of lung cancer can mean the difference between surviving and becoming a statistic.

The Early Lung Cancer Symptoms

Since the early signs of lung cancer can easily be mistaken for other conditions, it’s often difficult to take them seriously. However, if you’re experiencing a chronic cough that doesn’t appear related to a virus or allergy, wheezing, chest pain, bouts of bronchitis, or a persistent fever … it’s time to pay attention.

Lung cancer symptoms are often related to the location of the lesions, which settle into the tissues of the lung first. That’s why the early signs tend to reflect common cold, flu, and bronchial illnesses. Once the cancer moves beyond the bronchia, new symptoms arise.

The Later Lung Cancer Symptoms

Once lung cancer has metastasize and moved beyond the bronchia, the signs can expand dramatically. For instance, if the cancer has spread to the brain, then common signs might include blurred vision, stroke, and migraines. As you can see, these are serious symptoms that could be related to any number of illnesses. The point is this: don’t dismiss them.

In addition, signs such as depression, weight loss, fatigue, shoulder pain, difficulty swallowing, and hoarseness should be taken seriously.

When To See A Doctor

While you don’t want to be running to your doctor every time you get the sniffles, if the above signs show themselves, especially if they’re persistent, it’s better to be safe than sorry. This is particularly true if you’ve been a smoker or are currently smoking, or if you’ve ever been exposed to asbestos over an extended period.

It only takes a few hours out of your life to make an appointment and visit your doctor. Here are the signs that should inspire action:

- Unexplained loss of weight
- Persistent shortness of breath
- Stubborn respiratory infections that keep coming back
- A chronic cough that has no apparent cause
- Pain in your chest
- Wheezing
- Fatigue (again, if it has no apparent cause)

The point to remember is that your immune system is busy fighting the cancer. This is why you may find yourself constantly run down and battling nagging infections. It’s also one of the reason you may experience mood changes and irritability.

Conclusion

There is a caveat, unfortunately. Nearly a quarter of the people diagnosed with lung cancer never experience any symptoms at all. So while these lung cancer signs can serve as red flags, their absence doesn’t necessarily mean everything is just fine. Another reason to see your doctor for an annual checkup.

There are several types of lung cancers, some of which have distinct symptoms, while others are characterized by an absence of any kind of symptoms even in their most advanced stages. This absence of symptoms can make the already difficult task of detecting lung cancer even more difficult.

Here are some of the different types of lung cancer and some of the pertinent facts about each one of them.

The different types of lung cancer are categorized into two basic types: small cell and non-small. Mesothelioma is yet another kind of cancer that affects the lining of the lungs. Some of the more common symptoms include:

-Pain in the chest
-A persistent cough that is present for a long time
-Wheezing sound while breathing
-Shortness of breath
-Presence of blood in the sputum
-Unexplained weight loss
-Fever
-Swelling in the face or neck area

Symptoms are typically unnoticeable especially during the early stages of the disease, making the detection of the disease even more complicated than ever and making it difficult to determine whether or not it is necessary to seek medical attention. In the absence of symptoms, knowing the risk factors for lung cancer could help you make a more informed decision.

Considering smoking is one of the major risk factors for contracting lung cancer, giving it up is the first step towards reducing the likelihood of getting any kind of lung cancer. Giving up smoking also lowers the risk of developing other forms of cancer including cancer of the larynx and the throat as well as other parts of the body. A sedentary lifestyle and a poor diet are the other common risk factors.

Studies reveal that almost three thousand people who are non-smokers develop lung cancer every year by inadvertently inhaling second-hand smoke. Unfortunately, despite the fact that no cigarette has touched their lips, they have the same susceptibility rate and the same symptoms as those who smoke.

If you or a loved one suspects the presence of any of the above-mentioned lung cancer symptoms, a visit to the doctor is called for. The fast-multiplying and rapid-spreading nature of the disease, makes early detection all the more important. Though it may not exactly be life-saving, the earlier you detect the presence of any lung cancer symptoms the earlier treatment can be sought, increasing the chances of retarding the progress of the disease. Prevention is of course better than cure and knowing what the risk factors are can help you avoid them, thus lowering your odds of contracting the disease.

Knowing and understanding the early symptoms of lung cancer is one of the most important things that those who are at risk for the disease can do. Lung cancer is the most treatable when it is discovered early, and the only way to discover it early enough is to recognize and report the early symptoms of lung cancer. If you are noticing a combination of these lung cancer symptoms, be sure to talk to your doctor.

One of the early symptoms of lung cancer is a nagging cough that simply will not get better. Often the cough worsens with time and is accompanied by chronic chest pain. Coughing up blood is another of the many early symptoms of lung cancer. In fact, coughing up blood is one of the biggest symptoms that sends lung cancer patients to their doctors. Recurring bronchitis or pneumonia sometimes indicates that the disease is present. Fatigue and shortness of breath are more symptoms to watch out for if you suspect the disease. No matter what the symptoms are, if you have lung cancer, they will gradually progress in intensity as the disease progresses.

These lung cancer symptoms do not always indicate that the disease is present. There are other far less dangerous conditions that can cause these symptoms. However, ignoring the symptoms is dangerous, because if they are pointing to lung cancer, the disease will continue to progress. Early treatment is the best way to successfully fight lung cancer, so do not ignore these symptoms.
