Lung Tumors

Each bronchus then divides again forming the bronchial tubes. The bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. The average adult's lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide follows the same path out of the lungs when you exhale.

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.

This type of cancer is more common in women. It is also more likely to develop in young smokers. Adenocarcinoma usually grows at a slower rate, and doctors are likely to detect it before it spreads to other organs. The cancerous tissues usually form tumors on the outer parts of the lung. If a physician detects adenocarcinoma tissues in the early stages, the patient is likely to respond to conventional treatments.

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

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

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

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

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.

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.,

Lung cancer is one of the most common cancers in developed countries. Normally, our cells grow and multiply, as and when the body needs it. In lung cancer (as in other types of cancer), some cells may be damaged so as to start to grow and reproduce uncontrollably and, in most cases, faster than the normal cells. Lung cancer non-small cell (NSCLC) is the most common type of lung cancer and affects about eight out of 10 patients with the disease.

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.

Cellular / Molecular Basis: Lung cancer has two types; small cell and non small cell. The two types can be identified by their appearance when looked at with a microscope. It usually affects the cells that are lined along air passages in the lungs.

A more specific definition of lung cancer is that it is a type of cancer that happens when a cell starts to grow uncontrollably, forming a tumor in one or both lungs (2). Although lung cancer can start in other places of the respiratory system, it usually begins in the lining of the bronchi (3). It begins due to a change, or mutation, in a cell's genetic material, which leads the cell losing its ability to control its growth (2). This mutation is caused by environmental or hereditary reasons, but doctors usually are not able to identify the exact cause (4). However, it is important to examine a cancerous cell under a microscope because that helps the doctors identify the type of lung cancer, so they can give the best treatment to the patients

Lung cancers are broadly categorized as non–small cell (NSCLC) and small cell (SCLC) lung cancers, accounting for around 85 and 15% of all lung cancers, respectively. The most common histologic subtypes of NSCLC are adenocarcinoma (50%), squamous cell carcinoma (35%), and large cell lung cancer (15%). Subtypes of adenocarcinoma include broncho-alveolar, acinar, and papillary; subtypes of large cell lung cancer include giant cell and clear cell carcinomas, both of which carry poor prognosis. Adenocarcinomas are the histologic type associated with smoking.

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.”
