An Organ Of The Lung Cells

What are lung cancers? Lung cancers are the abnormal cells which grow in uncontrolled manner in one or both lungs. They do not function as normal lung cells and do not develop into healthy lung tissue. The abnormal cells can grow, form tumours and interfere with the normal functions of the lung (Lungcancer.org, 2015). Lung cancers can be divided into two major types, namely non-small cell lung cancers (NSCLC) and small cell lung cancers (SCLC). NSCLC can be further classified into three main subtypes, namely adenocarcinoma, squamous-cell carcinoma and large-cell carcinoma (Longo & Harrison, 2012). Lung cancers can be diagnosed by chest X-ray, computerised tomography (CT) scan, positron emission tomography-computerised tomography (PET-CT) scan, bronchoscopy and biopsy (Nhs.uk, 2015). Unfortunately, lung cancers are often diagnosed at the later stages. This is due to the unrecognisable symptoms and warning signs at the earlier stages. NSCLC are often diagnosed at stage IV which accounts for 30-40% of cases whereas 60% of SCLC is diagnosed at stage IV. Lung cancer usually originates from the cells lining the bronchi, bronchioles and alveoli. Carcinogens especially tobacco smoke will alter the gene expression of the normal human lung cells, resulting in cell mutation. The proto-oncogenes will be converted to mutated form, oncogenes. Mutation leads to the decreased expression of the tumour suppressor genes. This results in uncontrolled cell proliferation, cell

A common form of cancer that is very popular today is lung cancer. Lung cancer is a very dangerous form that can cause problems in simple body functions. These simple body functions are short breath and general fatigue. Lung cancer is commonly formed from smokers that has been exposed to that activity for numerous years. Lung cancer can also be spread by being exposed to asbestos or other pollutants. This form of cancer has many risk factors to it. These risk factors are high levels of air pollution, arsenic drinking water, and radon gas. Radon gas is a gas that is highly radioactive and is very sensitive to the body. Once radon is exposed to the body, it has a very high respiration rate which initially divide its radioactive cells- causing more significant damage to the body.

Lung Cancer is a disease which consists of uncontrolled cell growth in lung tissues. Lung cancer consists of two types, Non-small cell lung cancer, and small cell lung cancer. (NSCLC) is the most common type of lung cancer. The bronchi are the large air tubes leading from the trachea to the lungs that convey air to and from the lungs, and where most lung cancers begin. The body normally maintains cell growth only

Brief Description: Lung cancer, as with all cancers, is an uncontrollable increase of cells. It happens within the lung tissue, but it could also go on to affect other nearby tissue and spread to further out than just the lungs.

Lung cancer is a genetic and acquired disease. Lung cancer is genetic because cancer in general is caused by changes to the genes that control the way our cells function, especially how they grow and divide. All of these changes include mutations in the DNA that makes up our genes. Genetic changes that increase cancer risk can be inherited from our parents, if the changes are presents in germ cells. Which are the reproductive cells of the body, those are the eggs and the sperm. Lung cancer is also acquired because as the result of errors that occur as cells divide a person’s lifetime or exposure to certain chemicals. Some examples of these chemicals are found in tobacco smoke, radiation, UV rays from the sun that damage DNA. “In general, cancer cells have more genetic changes than normal cells. But each person’s cancer has a unique combination of genetic alterations.” Some of these changes may be the result of cancer, rather than the cause. As the cancer continues to grow, additional changes will occur. Even within the same tumor, cancer cells may have different genetic changes.

Beneath the lungs, a slender, arch formed muscle called the stomach isolates the mid-section from the guts. When you inhale, the stomach climbs and down, compelling air all through the lungs. Lung tumor begins when cells of the lung get to be anomalous and start to become crazy. As more disease cells create, they can frame into a tumor and spread to different regions of the body. Non-little cell lung growth is a gathering of lung tumors that act likewise, for example, squamous cell carcinoma and adenocarcinoma. Side effects are a hack that won't leave, shortness of breath, weight reduction, or hacking up blood. Medicines incorporate surgery, chemotherapy, and radiation. Lung disease begins when cells of the lung get to be strange and start to become crazy. As more malignancy cells create, they can frame into a tumor and spread to different ranges of the body. Around 80% to 85% of lung growths are non-little cell lung malignancy (NSCLC). There are subtypes of NSCLC, which begin from various sorts of lung cells. Be that as it may, they are assembled together as NSCLC on the grounds that the way to deal with treatment and guess are regularly

As generations of diseases and cures continue to be created, the increase of cancer multiply each day. Although there are many recurring cancers through genes and natural behavior, lung cancer is one of the recurrent cancers that continue to grow; either it has to do with natural behavior or genetics. Lung cancer begins to occur when cells in your lungs begin to grow uncontrollably. This disease is infectious and severe because not only will the cancer affect your lungs which affects your breathing, but also spread throughout your body and affect other organs as well

Tobacco use is the number one cause of lung cancer, but people who don't smoke may get lung cancer secondhand. The risks of developing lung cancer are related to three main factors: the age when a person started smoking, how long a person has

Lung cancer is a malignant lung tumor defined by uncontrolled cell growth in tissues of the lung. Malignant tumors of this type can expand throughout the person's body through their bloodstream or lymphatic system. Lung cancer is very life-threatening; it is a leading cause of cancer death in men and women in the United States. Lung cancer is one of the most typical cancers in the world. Lung cancer has the ability to transfuse to any organ in the body, although some organs are more commonly touched; such as the liver, brain, and adrenal glands. Lung cancer can also involve in the bones as well. The lung's main function is the interchange of gases between the air a person breathes and the blood in their body. The lungs withdraw carbon dioxide

Lung cancer is strongly associated with cigarette smoking, both from the actual smoker and secondhand, although there are cases in which someone that has never smoked or experienced secondhand has had lung cancer. Pipes and cigar smoking are also factors of lung cancer, but the risks are not as high as cigarettes. Another cause known for lung cancer is asbestos fiber. Asbestos fibers are silicate fibers that persevere in lung tissues after exposure to asbestos; which is something that can be picked up in a workplace where thermal and acoustic insulation is used. Smoking cigarettes increases the risk of developing asbestos-related lung cancer in workers.

A simple and understandable definition of lung cancer is: A disease which consists of uncontrolled cell growth in lung tissues. Lung cancer consists of two types: Non-small cell lung cancer, and small cell lung cancer. "(NSCLC) is the most common type of lung

Aside from the obvious cause of lung cancer, which is smoking, there are several others. However, almost all of these can be avoided. Preventable risk factors include smoking marijuana, inhaling certain chemicals like gasoline fuel or diesel exhaust, undergoing radiation therapy, and having a poor diet. But, the American Cancer Society affirms that about 87% of lung cancer cases are a result of smoking tobacco, and that some of the other 13% are caused by secondhand smoke (11). Out of all the risk factors for lung cancer, smoking has the biggest impact. This is also ironic, as smoking is the easiest factor to avoid. Theoretically this should be the least prominent factor, as it is a voluntary decision to start smoking and is easier to avoid than any of the other factors. Yet, about 47.1 million people in the United States smoke (American Heart Association), and willingly put themselves at risk for lung cancer. At the same time though, people do not start smoking just because they want to develop lung cancer later in life; there are numerous factors that play into their decision. For example, people are influenced to smoke for reasons such as peer pressure, a way to deal with stress, and people they look up to that smoke (Bonas). They think it will help them relieve stress, or fit in, and they do not think about the consequences that come with their newfound hobby. Eventually smokers find that they cannot quit, for both physical and psychological

There are more than seven thousand chemicals in tobacco smoke. Of those seven thousand chemicals about seventy of them are known to cause cancer. Smoking can cause cancer in many different parts of the body including but not limited to, lungs, liver, pancreas, bladder, and stomach. The number one cause of lung cancer is smoking. Smoking is also known to cause leukemia (Effects of Smoking on Your Health). Approximately one out of every three cancer deaths is due to smoking. Smoking can also cause diabetes mellitus, rheumatoid arthritis, macular degeneration, and multiple other symptoms (Surgeon General).

Smoking causes more than 4 in 5 cases of lung cancer. In fact, not every people who smoke get lung cancer but it increases the chance to get it.
