Lung Cancer Seriously Kills

Lung cancer kills more men and women than any other cancer does. It occurs most often in people over age 50 who smoked for many years. Lung cancer can develop when the lungs are damaged by repeatedly inhaling smoke (including second hand smoke which is even worst) or other harmful substances including asbestos, radioactive dust, and radon.
Having a combination of risk factors, such as being a smoker who works with asbestos, greatly increases you risks of developing lung cancer. Symptoms of lung cancer are similar to those of other chest and lung problems: chronic cough; shortness of breath; wheezing; hoarseness; repeated lung infections or pneumonia; pain in the chest wass, shoulders, or back; or coughing uppus- filled of bloody sputum. So beware because there may be no symptoms during the early stages. If you smoke, see your physician about any chronic respiratory symptoms and your risks in getting lung cancer.

Tobacco Smoke Carcinogens

Two active tobacco smoke carcinogens have been identified to be the most likely culprits that leads to lung cancer in heavy smokers. One is a nicotine-derivatitive and the other polycyclic aromatic hydrocarbons (PAH)have been isolated and identified to be the damaging constituents tnat leads to lung cancer. PAH, has been identified as the component that binds to DNA in the lung cells that causes abnormalities to occur resulting in mutations. The compound has also been found to contribute to supress or damage genes that are vital for the body to fight the disease weakening the defences of the body from within.

“This is the first demonstration of this link,” says co-author Ian Blair, PhD, Professor and Vice Chair of the Department of Pharmacology . “This is a second, but indirect, way in which PAHs can cause cancer. We also know that PAHs can also cause cancer directly.”

PAH, has the ability to cause the mutations in the cells alone and its ability to influence genes is something new that it surprised researchers that have been studying the results. Lung cancer is one of the leading forms of cancers responsible for deaths in the United States and better understanding of the disease such as this one leads to better treatment and management options to help those suffering from lung cancer.

Inhaled Insulin Treatment Causes Lung Cancer

Promoters of the alternative no-prick alternative to insulin intake have received another blow with industry leaders announcing their fears of detecting several cases of lung cancer in people who were receiving them under clinical trials. This is another in a long list of blows that the product has received and with many pharmaceuticals pulling the plug on research, the outlook seems bleak for the new diabetes treatment option. Many have been searching for alternative treatments for diabetes who have long been plagued by needles they use for administering the drug to supplement their insulin levels. The products were supposed to take away the pain and fuss of using syringes which is still the preferred method of administration.

Micro RNA shows Promise as treatment for Lung Cancer

A small molecule known as let-7 MicroRNA has been found to have beneficial effects on mice by reducing the growth levels of lung cancer cells. The study shows that the molecule in question has a direct role in treating cancers as we learn more and more about the possible causes and mechanisms that would lead to a cure for the many cases of the disease. The results were exciting for cancer researchers for they have been looking for the same results for many years without much success. The said that the same molecule is an agent that causes the disease to progress but heightened levels have been seen to have a counteractive effect on cancer cells. The study highlights the vast amounts of information that is still yet to be discovered that may hold the key to prevention and treatment of the killer disease.

Chemotherapy useless in Asbestos Induced Lung Cancer

Lung cancer that has resulted from inhalation of asbestos from the environment or through work related activities are showing that using chemotherapy for treatment is not getting any positive results. Called Malignant Plural Mesothelioma (MPM), the disease is more related to asbestos exposure which causes the lungs to develop lung cancer. The material was hailed as a miracle construction material and was used widely in the West due to heat, electrical and chemical resistance. It was only later that the material was found to induce cancer that had most nations ban the substance from all new building materials, and necessitating the removal of already installed ones from all types of structures. Clean-up crews without proper protection also suffer from the disease and oncologists are finding it hard to find proper treatments of the killer disease.

Premature Babies have higher risk of developing Lung complications

Premature babies that were delivered way before their bodies have fully developed receive a myriad of drugs to augment their still weak bodies that should have developed further in the mother’s womb. Studies have shown that babies who were delivered prematurely have a higher risk of lung problems due to the inability of their lungs to work properly without the administration of surfactants that are used to prevent their lungs from collapsing. Full term babies have fully developed lungs that can function unassisted but premature babies need the administration of surfactants (substances that prevents the lung’s air sacs from sticking together preventing them from inflating properly to absorb oxygen) to their lungs to get them to function properly. Without them, their lungs would constantly collapse (due to premature development) and can cause death. Current administration methods have shown that they can cause more harm to the infant in later life where lung infections become assured. The development of better administration techniques is underway to minimize the problems associated with their use to help their lungs strengthen in time as they mature.

Meat Raises Lung Cancer Risk

Diets that are high in saturated fats such as processed meats have a higher risk of contracting cancers in its many forms and shapes. The same goes with lung cancer for it is one of the most prolific forms of cancer the world over. Many die each year from cancers and lung cancer is one of the most dreaded for without proper treatment, mortality rate is high. More associated with other forms of cancer, red and processed meats used to be connected to colorectal, pancreatic and other cancers that afflict the organs of the body. Reducing the intake of the high fat proteins can greatly reduce the risks of contracting the many forms of cancer as with the elderly and people in their late adult lives.

Lung Cancer Surgery Effective for Elderly people

Statistics of the many lung cancer treatment operations are showing that they are indeed becoming better and improving the chances of reducing the spread of the disease in elderly people. Kung cancer being one of the most fatal forms of cancer once detected can easily benefit from the many forms of treatment now available. More advanced cancers that have not responded well to chemotherapy and other forms of treatment may necessitate the need to operate to remove the infected tissue and prevent the spread of the disease. Operations have successfully shown that they are effective even with the reduced lung capacity allowing patients to resume a quality life.

Bad For Health

Cigarette smoking is associated with an extensive selection of irregularities all the way through the body that cause not only illness, but also, all too often, death. Certainly, if all deaths from diseases related to smoking such as lung disease, heart disease, and cancers of other organs were considered, a case could be made for cigarette smoking as the foremost cause of death in industrialized countries. As luck would have it, it is also the most avoidable cause of death in our society. The expression “smoker’s lung” refers to the structural and functional defect in the lung caused by cigarette smoking.

At A Glance

Lung cancer is the number-one source of cancer deaths in both men and women all over the world. Cigarette smoking is the primary risk issue for enlargement of lung cancer. Passive contact to tobacco smoke can as well cause cancer. The two forms of lung cancer which in return, develop and broaden in a different way, are the small cell lung cancers (SCLC) and non-small cell lung cancers (NSCLC). The stage of lung cancer passes to the degree to which the cancer has proliferate in the body. Medications for lung cancer may entail a combination of surgery, chemotherapy, and radiation therapy in addition to newer experimental methods.
