Benign Lung Cancer Research Paper

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

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.

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.

the American Cancer Society there are benign tumors, which are rare and often develop in

One thing that we never want to hear a doctor say to us is that we have a tumor. Tumors are classified into two different classes, malignant or benign. Malignant are cancerous and are life threatening, while benign are not life threatening. Malignant tumors may spread to other parts of the body, while benign tumors stay in the place where they started. When the cells in a tumor are normal, it is benign. When the cells are abnormal and grow uncontrollably, they are cancerous cells. Looking at tumor cells through a microscope, cancer cells appear to have abnormal

Bronchogenic carcinoma accounts for over 95% of all primary lung tumours[53]. It is the leading cause of cancer deaths in both men and women worldwide accounting for approximately 27% of all cancer deaths[54]. This carcinoma is broadly divided into small cell lung carcinoma (SCLC) and non small cell lung carcinoma (NSCLC). Histologically, NSCLC is sub classified

The theme of this journal article was to explain to the audience the various sub types of non-small cell lung cancer, its risk factors, and the different procedures a patient has to undergo in order for them to be diagnosed with cancer. It does a great job answering a vast amount of questions the audience can have regarding the disease itself, the procedures used for prognosis and diagnosis of non-small cell lung cancer, and/ or the treatment available for patients with this disease. Overall, this report was very well detailed and provided the audience with a lot of

I decided to choose small cell lung cancer because I have 1st hand knowledge about small cell lung cancer and the effects it has on human lives. Many people who are diagnosed with small cell lung cancer are often diagnosed in the late stages. Small cell often spreads very quickly and is very aggressive .Many people believe that everyone who has lung cancer received lung cancer from smoking, which is often not true. Smoking does increase a person’s chance of lung cancer, but no everyone that has lung cancer got it from smoking. After researching the topic for a various amount of time, I learned that women who are nonsmokers are often diagnosed with lung cancer. Small cell lung cancer often starts in the bronchi near the center of the chest. Small cell lung cancer

Non-small cell lung cancer consists with 3 types of a tumor squamous cell carcinoma,acleno carcinoma, and large-cell carcinoma. “ 25 to 30 percent of primary lung cancers are squamous cell

Lung cancer tends to spread or metastasize very early after it forms; it is a life-threatening condition, and one of the most difficult cancers to treat. The lung is also a very common site for metastasis from tumors originating in other parts of the body. Lung cancers can arise in any part of the lung, but 90% - 95% of cancers of the lung are thought to arise from the epithelial cells, the cells lining the larger and smaller airways (bronchi and bronchioles) [22]. The etiology of lung cancer is mostly attributed to smoking. Tobacco smoking is the common cause of lung cancer; only 12% of cases occur in nonsmokers. Approximately 50% of new lung cancer cases are diagnosed in former smokers[23]. Even passive exposure to tobacco smoke increases the risk of developing bronchogenic carcinoma by 40% to 70%. Age, ethnicity, and genetic polymorphisms are also important factors; chronic obstructive lung disease is an independent risk factor for lung cancer [24]. Besides this, environmental factors such as ionizing radiation (e.g. soil radon) and exposure to asbestos, arsenic, chromium, nickel, and a number of other industrial substances also causes lung cancer. Air

Cancer is due to uncontrollable growth of cells. Cancer cells differ from normal cells as it alters from a systematic cell growth, division and apoptosis. Cancer forms when apoptosis fails to begin. Unlike normal cells, cancer cells do not experience programmed cell death. Hence, cancer cells will continue to multiply and segregate. This in turn, triggers a magnitude of abnormal cells that grow without limitation. Lung cancer occurs when abnormal cells develop within the lungs, causing disruption to the functions of normal lung cells. Lung cancers are highly due to the consequence of inhaling carcinogenic substances, such as tobacco and arsenic. These carcinogenic substances have damaging effects to DNA. Lung cancer is the leading cause of

Tumors are one of the most feared diseases of our time. Many people upon hearing the word “tumor” immediately resonate to the conclusion of it being cancer, which is not necessarily true. Tumors fall into to two main types, benign and malignant. Although they are considerably different in tissue invasion, their nature that makes them distinct and symptoms, they are also quite similar in the way they recur in the same location, growth size and their health risks.

Lung cancer is the leading cause of cancer deaths in Malaysia for both men and woman. Your lungs are two spongy organs in your chest. The left lung is divided into two lobes or sections, and the right lung has three lobes. When you breadth in air enters your nose or mouth and passes into your trachea or windpipe, at the carina the trachea divides into two bronchi then branches into smaller bronchioles. The bronchioles end in tiny air sacs or alveoli. In the alveoli the oxygen and the air you inhale passes into the bloodstream and carbon dioxide in your body passes out of the blood stream. The carbon dioxide is expelled from your body when you exhale. Your lungs are in cased by pleura, a thin membrane that protects them and helps them slide back and forth as you breathe in and out. Underneath your lungs is the diaphragm a smooth thin muscle that helps your lungs expand and contract as you breathe. Your lungs are connected to small collection of immune system cells called lymph nodes by way of lymphatic vesicles. You have groups of these lymph nodes near your lungs above your collar bones and behind your breast bone as well as in other parts of your body. Lung cancer is most commonly start in the bronchi, but they can also begin in the trachea, bronchioles, or alveoli.

Lung Cancer, like any other types of cancer, is an excessive production of lung cells. Human body has a maintain system of checks and balances on cell growth thus cells divide to produce new cells as it needed. Any changes of this balance system such as smoking Cigarette, high levels of air pollution, Arsenic poisoning, Radiation therapy and etc. These causative agents will lead to uncontrolled cell division which result excessive amount of cells eventually forms a mass known as a tumor.
