Lung cancer is now the most common form of cancer in the United States. Lung cancer causes more death than any other cancer cases among men and women in this country. Fourteen percent of all cancer records in the United States are lung cancer cases and twenty-eight percent of cancer deaths are from lung cancer patients.

Major causes of lung cancers are cigarette smoking and breathing impure air including asbestos exposure. Asbestos exposure can lead to Mesothelioma, a cancer in the lining of the lungs or abdominal cavity.

Severity of lung cancer depends greatly to the amount of time a person spent smoking. As compared to non-smokers, smokers are at high risk of lung cancer. In fact, smokers are twenty-two percent more at risk of acquiring lung cancer than their non-smoking counterpart.

Additionally, because lung cancer symptoms do not manifest until it is already on its advanced stage, minor lung cancer symptoms are often ignored.

This is because minor lung cancer symptom such as frequent coughing is often associated with itchiness in the throat. Smokers believe that this is an ordinary occurrence among smokers, thus they are not alarmed until they feel more severe lung cancer symptoms.

When this happens, truly the lung cancer symptom shows because of the advanced stage of the cancer. The uncontrolled growth of abnormal cells in the lungs is already manifesting through the lung cancer symptoms and by this time, secondary cancer cells are already developing in other organs of the body.

Severe lung cancer symptoms include persistent coughing, chronic chest pain, which is associated with shortness of breathing, wheezing and hoarseness of the voice.

Often, because of the similarity of lung cancer symptoms to bronchial asthma, people who self medicate usually try to treat the shortness of breathing with asthma medication.

The medication is thus useless because it is not working on the actual disease. It is thus imperative that minor discomforts such as shortness of breathing be brought to the attention of a competent doctor for evaluation. This will avoid treating a disease with a different medication such as in self-medicating patients.

Other lung cancer symptoms are blood in sputum, recurring cases of pneumonia or bronchitis, neck and facial swelling, sudden weight loss and constant feeling of fatigue. All these lung cancer symptoms occur on the terminal stage of the cancer, and this makes it almost impossible to manage lung cancer and it symptoms.

Additionally, because there is still no known cure for lung cancer, treatments especially on its advanced stage are done to lessen the severity of the lung cancer symptoms. Remission of the disease may no longer happen on the advanced stage.

Thus, it is imperative that minor lung cancer symptoms be monitored. It is still easier to manage lung cancer at this stage, other than in the advanced stage.

Finally, as mentioned earlier, smoking is the major cause of lung cancer, if you cease smoking, this effort will help you slow down the possibility of lung cancer. Even for those long time smokers, withdrawing from smoking will help lessen the possibility of acquiring the disease.

Keeping a healthy body and strong immune system will help avoid lung cancer for smokers or non-smokers alike.

Smokers may cease from smoking to help ensure they will not suffer lung cancer in the future. Then, they will not have to worry about lung cancer symptoms because halting smoking will also halt the possibility of acquiring this deadly disease.

Regular exercise will help ensure your immune system will be strong enough to fight lung cancer and thus no lung cancer symptoms will ever occur.

Living a healthy and active lifestyle, and avoiding smoking will ensure you will leave longer and better.

Lung cancer is a disease of uncontrolled cell growth in tissues of the lung. This growth may lead to metastasis, invasion of adjacent tissue and infiltration beyond the lungs. The vast majority of primary lung cancers are carcinomas of the lung, derived from epithelial cells. Lung cancer, the most common cause of cancer-related death in men and the second most common in women,[1][2] is responsible for 1.3 million deaths worldwide annually.

What causes lung cancer?

Smoking

The incidence of lung cancer is strongly correlated with cigarette smoking, with about 90% of lung cancers arising as a result of tobacco use. The risk of lung cancer increases with the number of cigarettes smoked over time; doctors refer to this risk in terms of pack-years of smoking history (the number of packs of cigarettes smoked per day multiplied by the number of years smoked).

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.

Cancer that originates from lung cells is called a primary lung cancer. Primary lung cancer can start in the airways that branch off the trachea to supply the lungs (the bronchi) or in the small air sacs of the lung (the alveoli). Cancer may also spread (metastasize) to the lung from other parts of the body (most commonly from the breasts, colon, prostate, kidneys, thyroid gland, stomach, cervix, rectum, testes, bone, or skin).

Lung Cancer Symptoms

Lung cancer symptoms are commonly not experienced until the disease had advanced, sometimes delaying diagnosis. The symptoms of lung cancer also mimic the symptoms of other benign illnesses.

The most common lung cancer symptoms experienced are :

Onset of wheezing

Recurrent pneumonia or bronchitis

A persistent cough that does not go away

A sign is also an indication that something is not right in the body. But signs are defined as things that can be seen by a doctor, nurse, or other health care professional. Fever, rapid breathing rate, and abnormal breathing sounds heard through a stethoscope may be signs of pneumonia.

Lung Cancer Diagnosis

To help find the cause of symptoms, your doctor will evaluate your medical history, smoking history, exposure to environmental and occupational substances, and family history of cancer. Your doctor also will perform a physical exam and may recommend a chest X-ray and other tests. If lung cancer is suspected, sputum cytology — the microscopic examination of cells obtained from a deep-cough sample of mucus in the lungs — is a simple test that may be useful in detecting lung cancer. To confirm the presence of lung cancer, your doctor must examine tissue.

How can I prevent lung cancer?

The best way to prevent lung cancer is to quit smoking, or to never start in the first place. You should try and avoid being around people who are smoking; and also avoid pipes, cigars, and marijuana. If you live in an area with radon, you should make sure there is adequate ventilation in your basement to get rid of it. Use a detector to make sure the radon levels are low.

Treatment Of Lung Cancer

Many factors must be taken into account to determine the best treatment for an individual diagnosed with lung cancer. The specific type of cell, the location of the lung tumor, the stage of the disease with possible metastasis (spread to other parts of the body), and the general health of the individual must be considered. Various treatment plans may include radiation therapy, chemotherapy, and/or surgery.

One vital aspect of recognizing the symptoms of lung cancer is knowing your body and listening to it. Once you are in tuned with your body you will know when to take action. Symptoms of lung cancer usually will occur in the breathing part of your body also known as the respiratory system. If you experience any or all symptoms; you should schedule an appointment to see your doctor right away.

If you have a persistent cough that lasts more than 3 weeks. This is usually indicative of a respiratory infection or early stages of lung cancer which requires immediate attention from your doctor. If you smoke you may have what is referred to as the smoker’s cough.

This cough alone will cause a persistent cough so if you smoke; regular visits to your doctor is imperative because the cough can convert into cancer without you knowing it; and that is because you are so accustomed to coughing. So don’t take that for granted. If you smoke; quit. Smoking is like puffing on cancer sticks.

What if you don’t smoke and you have a persistent cough for more than 3 weeks. You may have been around people who smoke constantly or exposed to an area where there was constant smoke.
Another symptom of lung cancer is blood or brown tinged colored sputum. Sputum is mucus that you cough up when you have a cold. If you do not have a cold and you cough this up in the morning or during the day pay attention to the color.

The normal color for sputum is clear white or clear pale. Being more lethargic than usual is another sign to look out for. We all experience times when we have less energy; but if you see yourself tiring more often than usual then you may need to take action. Knowing your body ;paying attention to it and taking action can destroy lung cancer in its tracks before it gets out of hand.
