Primary Lung Cancer

Lung cancer is the most commonly diagnosed cancer in the world, according to the World Health Organisation. In the UK, it 's the second most-frequently occurring cancer among men (after prostate cancer), accounting for 1 in 7 new cases, and the third most-frequently diagnosed cancer in women (after breast and bowel cancer) accounting for about 1 in 9 new cases. However, numbers have dropped considerably in recent times, by about 16% in the last decade alone.

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

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 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

Treatment: As long as the cancer has not spread to outside of the lung, it can be removed with surgical resection. There are now less invasive ways to remove cancer from the lungs, such as using a small video camera to see inside the chest, resulting in smaller incisions. There has very recently been a new way to treat non small cell lung cancer that would otherwise be inoperable. Shown to be more effective than normal radiation therapy and simply observing the cancers progress, stereotatic body radiation therapy can ???. Laser treatment is sometimes used to unblock air passages that are blocked by a tumour and attempt to control some spreading of the cancer cells. It is different to the other ‘treatments’ as it doesn’t actually provide a solution to getting rid of the cancer, but makes the symptoms more bearable for the patient.

Although many people have heard about lung cancer, they don't know that there are two major types of lung cancer. The types of lung cancer are non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC breaks down into three different types and approximately makes up 85-90% of the cancers that patients are diagnosed with. The first type of NSCLC is adenocarcinoma. This type of cancer is usually found in smokers however it is the most common lung cancer found in nonsmokers. This cancer typically attacks younger adults and targets women. This cancer tends to develop on the outside layers of the lungs and it can be found before it spreads throughout the body. The second type of NSCLC is squamous cell carcinoma. This cancer is linked to smoking and forms in the inner airways of

This sort of lung malignancy happens primarily in present or previous smokers, however it is additionally the most widely recognized kind of lung disease seen in non-smokers. It is more normal in ladies than in men, and it will probably happen in more youthful individuals than different sorts of lung tumor. Adenocarcinoma is typically found in external parts of the lung. Despite the fact that it has a tendency to become slower than different sorts of lung malignancy and will probably be found before it has spread, this fluctuates from patient to persistent. Squamous cell carcinoma: Around 25% to 30% of all lung malignancies are squamous cell carcinomas. These tumors begin in early forms of squamous cells, which are level cells that line within the aviation routes in the lungs. They are regularly connected to a past filled with smoking and have a tendency to be found in the focal part of the lungs, close to a primary aviation route. Huge cell carcinoma: This write represents around 10% to 15% of lung diseases. It can show up in any part of the lung. It has a tendency to develop and spread rapidly, which can make it harder to

Lung cancer is a very common to be diagnosed with and harmful to anyone who is exposed to many resources around the world: smoking (first hand and second hand) and pollution. Any resource that is made up of chemicals that are exposed into the air that people breathe, give the risk of affecting others with lung cancer. However, since smoking is the most popular way to cause lung cancer, many people are exposed to it from either firsthand or second hand. First hand smoking is when the person being affected is indirect contact with the source that is giving off the toxins, while secondhand is when the one being affected is not directly connected to the main source. Either way the chemicals and toxins that come from harmful resources soon will build up and affect one’s normal body

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).

SCLC is most regularly centrally situated tumour arising up from bronchial epithelium (Belinsky, 2004). Facts reveal 92% of patients had NSCLC, whereas 8% have been recognized with small cell carcinoma. The foremost commonplace anatomy changed into adenocarcinoma (43.8%) followed with the aid of squamous cellular carcinoma (26.2%), large cell carcinoma (2.1%) and others (8.3%). statistically better occurrence of the adenocarcinoma in non-people who smoke and small cellular and squamous histology had been more commonly located within the smokers [Noronha et al.,

Large amounts of non-small-cell lung cancer cases are caused by smoking, and many others are caused by exposure to secondhand smoke. Smoking is the most common factor that led to non-small-lung cell cancer.Smokers face other risk factors such as radon and asbestos. But the fact is that not everyone smokes with lung cancer. Lung cancer in nonsmokers may be due to exposure to radon, get the chemicals gas from one who smoking, air pollution or many other reason such as the bad chemicals, or working at the workplaces exposure to asbestos can also cause non-small-cell lung cancer. Non-smokers often have cancer at a younger age than smokers.

The most common cause of lung cancer is smoking cigarettes. 80% of people who have lung cancer got it from smoking. The longer you smoke cigarettes the better chance of getting lung cancer. Smoking at a young age increases the chance of getting lung cancer more then starting to smoke as an adult. The sooner you quit, the better your life will be. Passive smoking (secondhand smoking) can give you lung cancer if exposed for a long time to it.

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.
