Lung Cancer Synthesis

Lung cancer occurs when a odd cells in the lung grow in an uncontrolled way. It often spreads to other parts of the body before the cancer can be identify in the lungs. Lung cancer is 1 of the 10 most common cancers in both men and women in Australia.

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 doctor can diagnose lung cancer through many tests. The doctor can have x-rays and CAT scans done to see what the inside of the lungs look like. By doing this that doctor is able to see what stage the cancer is in. A doctor may also do a test called a bronchoscope. This test allows the doctor to look inside the bronchial tubes and biopsy the tumor. The doctor then can take a small amount of the cells to study them to determine if the unusual cells are cancerous. If the cells turn out to be cancerous then the patient is in for many months even years of harsh treatment.

Lung Cancer, like any other type of cancer, is the uncontrollable growth of cells in the lung tissue. The main causes that contribute to lung cancer include inhaling carcinogens (basically, smoking), exposure to ionizing radiation, viral infections and even air pollution. These factors basically damage the tissues lining the bronchi in the lung, leading the cancer to develop further (Vaporciyan & Nesbitt JC, 2000). Primary lung cancers that develop in the epithelial tissues of the lung are known as carcinomas and claim the top spot in terms of leading cancer-related death causes. As of 2004, lung cancer

Lung cancer is a cancer (malignancy) that originates in the tissues of the lungs or the cells lining the airways. Lung cancer originates when normal lung cells become cancer cells, usually after a series of mutations, and begin to divide out of control.

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 cancer that originates in the lungs. Lung cancer often goes undetected in the early stages, since symptoms don't usually present themselves until the advanced stages of the disease.

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

Lung cancer is a tumor that affects either one or both of the lungs.A primary cancer begins in the lungs and a secondary cancer begins in another place in the body and makes its way up towards the lungs. Lung cancer is the 5th most common cancer. In Australia 59% of males were diagnosed were as 41% of Australian females were diagnosed.

Lung cancer occurs due to cells in a person’s lungs that multiple at a rapid pace, which form a malignant tumor. These tumors in the lungs take away important necessities such as oxygen, and nutrients; diminishes the ability of the tissue to properly function. One of the most type of common lung cancers is Adenocarcinoma, which make up to forty percent of these cases. Smoking is the primary reason for Americans to be diagnosed with lung cancer, with a cigarette containing more than 4,000 chemicals that have permanent damage to the lungs causing long term effects (Conrad 2016).

It is wise, however, to have a doctor monitor the tumor over at least a two-years period in order to note any changes that might indicate the presence of cancer. Also, a biopsy or surgical removal of a tumor may be needed when the patient is a smoker, the patient has difficulty breathing, or other troubling symptoms, tests show that the cancer could be present, and the nodule continue to grow. The malignant lung cancer is divided into non- small cell lung cancer, small cell lung cancer, and lung carcinoid tumor. First, the non- small lung cancer is A group of lung cancers that are named for the kinds of cells found in the cancer and how the cells look under a microscope. The cancer cells of each type grow and spread in different ways. The three main types of non-small cell lung cancer are squamous cell carcinoma, large cell carcinoma, and adenocarcinoma. Non-small cell lung cancer is the most common kind of lung cancer. The first type of the non- small cell cancer is squamous cell carcinoma About 25% to 30% of all lung cancers are squamous cell carcinomas. These cancers start in early versions of squamous cells, which are flat cells that line the inside of the airways in the lungs. They are often linked to a history of smoking and tend to be found in the central part of the lungs, near a main airway (bronchus). The second type is larger cell carcinoma this type accounts for about 10% to 15% of lung cancers. It can appear in any part of the lung. It tends to grow and spread quickly, which can make it harder to treat. A subtype of large cell carcinoma, known as large cell, neuroendocrine carcinoma, is a fast-growing cancer that is very similar to small cell lung cancer. The third type of non- small cell lung cancer is adenocarcinoma about 40% of lung cancers are adenocarcinomas. that begins in the cells that line the alveoli and make substances such as

Imagine you are running and with each step your breath becomes shorter and shorter. Your lungs are working twice as hard and you have not even gone half way. Sweat is running down your forehead as is becomes harder for you to breath. You used to be able to run with such ease but now you are out of breath. While thinking back at what has changed to make your breathing so heavy you drop your pack of cigarettes. Smoking cigarettes is a dangerous habit. Not only can it cause cancer and other health problems to yourself but it can also pose a risk to others. Many people get addicted to smoking cigarettes. They may have been pressured into trying one or have seen a commercial about smoking and wanted to try it out for himself. Some find pleasure in smoking and use it as a relaxation from their stressful lives but that is not a good enjoyment.

Lung cancer is the number one cause of death by cancer. It has affected my family tremendously. My grandma was diagnosed with stage four lung cancer in June of 2014, it has been almost two years and she is still fighting. She has gone through so much and it really takes a toll on your body. She has gone through years of chemotherapy, radiation, so many drugs and recently was put on oxygen that she needs 24/7. I pray every day that people will stop smoking and not take the risk of developing lung cancer.

Lung cancer is the number one leading cause of cancer deaths in the United States. Lung cancer kills more people than any other cancer, such as; breast cancer, colon, prostate, or ovarian. There are two types of lung cancer, small cell lung cancer and non-small lung cancers. These two lung cancers grow and spread differently. Small cell lung cancer tends to spread quickly and makes up about 10-15 percent of the lung cancers. Non-small lung cancer is the most common type, it attributes to about 85 percent of lung cancers. The sub types of non-small cell lungs cancer are; squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. People who smoke have the greatest risk of lung cancer. If you quit smoking you can significantly reduce your chances of developing lung cancer. The overall prognosis is poor, lung cancer is usually not found until it is in its advanced stage. According to the Mayo Clinic “Five-year survival is 40% to 50% for early stage lung cancer, but only 1% to 5% in advanced, inoperable lung cancer.”
