lung cancer
You've probably heard that the antioxidants found in certain foods and red wine can offer some protection from breast cancer
, heart disease and stroke. According to new research set to appear in October's Cancer Epidemiology, Biomarkers & Prevention, we could soon be adding lung cancer symptoms to that list.
"An antioxidant component in red wine may help to prevent lung cancer," according to lead researcher Chun Chao a research scientist with the Kaiser Permanente Southern California Department of Research and Evaluation. "The findings provide an impetus for further research to find out if there is something in red wine that may help to either prevent or treat lung cancer."
Scientists believe that antioxidants, like those found in red wine and other foods, are somehow able to protect cells from oxidative damage that comes from free radicals and can strike any part of a cell, proteins, the membrane, even the DNA itself. Cellular damage caused by free radicals has been implicated in the development of cancer.
Researchers used the California Men's Health Study to identify 210 lung cancer patients from the 45 to 69 year old men who were members of a large, prepaid health plan in California. The researchers looked at cancer rates and consumption of red and white wine, beer and other liquor. They found that, on average, there was a 2% lower risk of lung cancer associated with each glass of red wine a subject drank per month. So... a man who drinks 30 glasses each month would lower his risk of lung cancer by 60%.
Of course, any smoker's risk of lung cancer is higher than a non smoker's risk. We all know that, right?
The team found the biggest effect on risk seemed to come to male smokers who drank one to two glasses of red wine per day. Makes you wonder if the red wine somehow... rises to the challenge of the toxic chemicals in the smoke?
You notice the emphasis on red wine? There are two reasons for this...
1. The study found no reduction in risk in men who drank the same amounts of white wine, beer or liquor. Only red wine had the effect.
2. Red wine uses the whole grape, seeds, skins and all, which keeps vital antioxidants known as polyphenols in the wine, in a form ready to be absorbed and used by the body.
Of course, many are quick to point out that one study doesn't prove that red wine has any protective effects. Sometimes early work like this, on further research, doesn't stand up. And the researchers themselves are quick to insist that this study doesn't mean smoking is something you should continue to do, or that red wine will protect a smoker from developing lung cancer.
"Clearly, we aren't recommending that smokers go out and start consuming large amounts of red wine as a potential protection from getting lung cancer," says Dr. Leonard Lichtenfeld, deputy chief medical officer of the American Cancer Society, "There are other research reports that show any alcohol, including red wine, can increase the risk of other cancers such as breast cancer."
And of course you don't have to rely on red wine to increase your levels of anti-oxidants each day. Eating 5 - 9 portions of fruit and vegetables will mean you're giving your body the right kind of fuel to fight free radicals helping to minimize the risk of lung cancer symptoms.

Lung Cancer – Symptoms and Causes of Lung Cancer
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.

Searching for the Right Lung Cancer Treatment
Lung cancer is one of the most common forms of cancer. If you have been diagnosed with lung cancer, the next thing you should do is to discuss with your doctors the most suitable lung cancer treatment for you. There are various options available for the treatment of lung cancer, but you will need to discuss these options carefully with your doctors and family before making a decision on the treatment method. Please bear in mind that the earlier the cancer is treated, the better will be your prognosis from this deadly disease.
Surgery is obviously one of the more effective treatment for removing the cancer from the body, however it all depends on how far along the cancer is. CT and PET scans are used to determine is the cancer can be removed through surgery, or if it is too far along and has spread to other areas making it harder to perform surgery. Blood tests and spirometry or lung function testing are also used to see if the patient can be operated on. Surgical procedures include wedge resction or partial removal of the lobe, a lobectomy or removal of one lobe, a bilobectomy or removal of two lobes, and pneumonectomy or the removal of an entire lung. A lobectomy is the most common form of surgery because it reduces the chance of the cancer returning.
Chemotherapy is also used to reduce the risk of the cancer recurring. The kind of chemotherapy used depends on the type of cancer and where it is located in the lungs. Radiotherapy is often used along with chemotherapy.
Another form of lung cancer treatment besides these two is targeted therapy. Gefitinib is one such drug that targets the tyrosine kinase domain of the epidermal growth factor receptor. This has shown to increase the chances of survival in many of the people whom have taken this drug. Erlotinib is another drug that has been shown to increase the survival rate in cancer patients. Both of these drugs have been shown to be very effective in females, Asians and non-smokers.
Becoming diagnosed with lung cancer is a very serious thing to be told. There are several ways the cancer can be treated now but it is important to know all the lung cancer treatment options that are available to you. It is best to get surgery if at all possible, but if the cancer has spread into other areas, surgery is out of the question. Then chemotherapy, radiotherapy and targeted therapy can be considered. You should also explore the possibility of using other alternative cancer treatments. However, it is important for you to speak with your doctor the instance you have gotten lung cancer.
