Lung cancer is “the uncontrolled growth of abnormal cells in one or both lungs”. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, “the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood”. There are two major types of lung cancer, non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Staging lung cancer is based on whether the cancer is local or has spread from the lungs to the lymph nodes or other organs. Because the lungs are large, tumors can grow in them for a long
Lung cancer is an uncontrolled growth of abnormal cells that start off in one or both lungs they usually in the cells that line the air passages (medianews). The cells from the abnormal can’t develop into a healthy lung tissue and spread quickly and form tumors.
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.
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
The human body is designed so that each part is dependent on the other for one or the other reason. There is a delicate balance to the distribution of functions and the way in which each system defenses itself against any unmentionable disease or ailment.
There are two different types of lung cancer, non-small cell lung cancer and small cell lung cancer. It is all depending on the size of what the cells look like under a microscope. Both of these types of lung cancer can grow differently which leads to them both being treated differently. Non-small cell lung cancer is the more common of the two and it usually grows fairly slow. There are three main types of non-small cell lung cancer and they are squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. Small cell cancer is the least common and it grows fairly rapid and it can easily spread to other organs in the body (Cavendish, p.946).
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 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.
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
With more than 1.61 million cases recognized annually lung carcinoma is that the leading cause behind cancer connected loss of life among men and second main cause in the back of loss of life in women worldwide [Jemal et al., 2011]. Morphologically the lung cancer is divided into small cell lung carcinoma (SCLC), non-small cell lung carcinoma (NSCLC) and adenocarcinoma (AC), with non-small cell carcinoma (NSCLC) accounting for 80% of all cases. [Brambilla et al., 2001]. The medical accomplishment in two decades has provided least effect on the treatment of the most cancers, the overall five year survival rate of NSCLC is roughly 15%.
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
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 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.
Small cell lung cancer often starts in the bronchi near the center of the chest. Small cell lung cancer often grows and spreads very quickly and often spreads to distant parts of the body before it is found. Lung cancer is second most common cancer in men and women. Lung cancer currently accounts for a quarter of cancer deaths and is
Lung cancer is a type of cancer is found in men and women lung cancer have something to do with your lungs. Your lungs which help pump oxygen into your body and also release carbon out of your body which helps you live because you need oxygen. Lung cancer is a common cancer in ages 60 and up it can also be found in any age but is most commonly in 60 year olds and older. Lung cancer is the leading cause of cancer deaths in the U.S. in both men and women. Lung cancer is also one of the most preventable kinds of cancer, but smoking is mainly the leading cause of lung cancer.
