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.
Lung cancer has multiple ways of impacting a body. This depends on the stage of lung cancer and when it becomes diagnosed. At early stages, lung cancer patients are often unaware that they have the disease. As the disease becomes more advanced, variable symptoms can develop. They often present with respiratory symptoms such as cough, shortness of breath, or blood with coughing. Common places
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
Cancer is a genetic disease caused by certain changes to genes that control the way our cells function, especially how they grow and divide. Genes carry the instructions to make proteins, which do much of the work in our cells. Certain gene changes can cause cells to evade normal growth controls and become cancer. Genetic changes that promote cancer can be inherited from our parents if the changes are present in germ cells, which are the reproductive cells of the body (eggs and sperm). Such changes, called germline changes, are found in every cell of the offspring. In general, cancer cells have more genetic changes than normal cells. But each person’s cancer has a unique combination of genetic alterations.
Lung cancer takes many years to develop. The characteristics of lung cancer the same as any type of cancer but it effects the lungs. Lung cancer is caused by expose to carcinogens
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, 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.
The leading cause of cancer death for both men and women in the United States and worldwide is lung cancer. Lung cancer is responsible for thirty percent of cancer deaths in the United States. The deaths caused by breast cancer, colon cancer and prostate cancer combined do not add up to the deaths that lung cancer causes. In 2007, 158,683 people, 88,243 men and 70,354 women died from lung cancer in the United States (Eldridge, 2012). Out of the 158,683 people that died from lung cancer in 2007, 135,000 of them died of lung cancer caused by smoking cigarettes. The overall survival rate of those with lung cancer is at about fifteen percent.
Up to 25% of people with Lung Cancer don’t have symptoms, the other 75% of people do have symptoms such as; a new cough, or a cough that doesn’t go away, or changes is a good sign. Or with smokers they sometimes have chronic coughing and if it changes in how severe it is or how often they cough that could be a red flag. Chest, shoulder, and back pain that also does not go away and gets worse with deep breathing is also a sign.
Cancer, it can affect anyone; it can affect any part of the body but what is it? Cancer results from the abnormality in the body's cells. This occurs when the cells divided and grow. Disruption in the system of the growth and division of a cell results in an uncontrolled division and proliferation of cells that form a mass which leads to cancer. The patient outcome for cancer is different for everyone, but it is also different with each type. In the respiratory department, a major type of cancer we will deal with is lung cancer. Lung cancer, however, has different types and stages, but for this paper, we are going to talk about Stage IIIA non-small cell lung cancer (NSCLC). In the article titled “Stage IIIA Non-Small Cell Lung Cancer” it states
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.
Cancer can be one of the hardest battles that one must face, whether that battle is lost or won, it changes the lives of everyone involved. Lung cancer is one of the most diagnosed cancers and it affects the lining of the lungs and the ability to breathe. Lung cancer is the number one killer of men and women than any other cancer worldwide. This cancer is mostly found in smokers and this is why professionals are targeting this population for testing for diagnosing early and possibly saving a life (www.ncb.nlm.nih.gov). Lung cancer refers to the malignancies that originate in the airways or pulmonary parenchyma.
MRI, PET, and bone scans are imaging tests that can tell if the cancer has spread to other parts of the body as well as providing additional information on the chest. Other types of tests can also be used to determine if a patient has lung cancer, such as thoracentesis, needle biopsy, and bronchoscopy.
Lung cancer can become suspected after a spot is seen on an x-ray that may have been taken due to a persistent cough, chest pain, etc.
