Lung Cancer: Malignant Tumors

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.

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.

It is wise, however, to have a doctor monitor the tumor over at least a two-years period in order to note any changes that might indicate the presence of cancer. Also, a biopsy or surgical removal of a tumor may be needed when the patient is a smoker, the patient has difficulty breathing, or other troubling symptoms, tests show that the cancer could be present, and the nodule continue to grow. The malignant lung cancer is divided into non- small cell lung cancer, small cell lung cancer, and lung carcinoid tumor. First, the non- small lung cancer is A group of lung cancers that are named for the kinds of cells found in the cancer and how the cells look under a microscope. The cancer cells of each type grow and spread in different ways. The three main types of non-small cell lung cancer are squamous cell carcinoma, large cell carcinoma, and adenocarcinoma. Non-small cell lung cancer is the most common kind of lung cancer. The first type of the non- small cell cancer is squamous cell carcinoma About 25% to 30% of all lung cancers are squamous cell carcinomas. These cancers start in early versions of squamous cells, which are flat cells that line the inside of the airways in the lungs. They are often linked to a history of smoking and tend to be found in the central part of the lungs, near a main airway (bronchus). The second type is larger cell carcinoma this type accounts for about 10% to 15% of lung cancers. It can appear in any part of the lung. It tends to grow and spread quickly, which can make it harder to treat. A subtype of large cell carcinoma, known as large cell, neuroendocrine carcinoma, is a fast-growing cancer that is very similar to small cell lung cancer. The third type of non- small cell lung cancer is adenocarcinoma about 40% of lung cancers are adenocarcinomas. that begins in the cells that line the alveoli and make substances such as

Throughout life, many individuals experience difficulties due to growing up in everyday life. While going in depth of the human life, it is discovered that there are many diseases and disorders that affect humans’ everyday functions. A very popular disease that has traumatically affected the human body is cancer. Cancer is a disease that spreads throughout your body in many ways. The purpose of cancer is to attach to a blood cell in your body and cause a plague within itself, causing the body to initially shut down and die. This disease contains many forms and have many causes to it. However its main goal is to destroy the human body.

(Transition: we have discussed the causes, lets look at the risk factors including some environmental ones.)

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.

Nanotechnology has immense numbers of avenues and directions that have been created, especially in the treatment of cancer. It is only projected to become a bigger field that’s more accurate as time passes. But is nanotechnology sustainable and though accurate, strong enough to be the best cancer therapy system? Is lung cancer too difficult to treat with nanotechnology due to its metastatic tendency? And is nanotechnology the best direction that we could be following in our quest for the treatment of cancer without damaging other tissues? As we discover more technology and tools, problems pop up as quick as we can solve past ones – toxicological aspects of cancer treatment, cost effectiveness and the like. Can these wonder child molecules created

Lung cancer is an uncontrolled growth of cells in the lungs, it can occur in only one lung or both. When cells in the lungs divide uncontrollably it eventually forms a tumor in the lungs. Tumors are a mass of the build-up

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%.

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 is a malignant lung tumor defined by uncontrolled cell growth in tissues of the lung. Malignant tumors of this type can expand throughout the person's body through their bloodstream or lymphatic system. Lung cancer is very life-threatening; it is a leading cause of cancer death in men and women in the United States. Lung cancer is one of the most typical cancers in the world. Lung cancer has the ability to transfuse to any organ in the body, although some organs are more commonly touched; such as the liver, brain, and adrenal glands. Lung cancer can also involve in the bones as well. The lung's main function is the interchange of gases between the air a person breathes and the blood in their body. The lungs withdraw carbon dioxide

Lung cancer is a malignancy that affects the functionality of the lungs. In the early stages of lung cancer there are hardly any symptoms than in the later stages where they begin to appear. Some of the symptoms that can appear is chest pain, a persistent cough, coughing up blood, weight loss, headaches, and wheezing.

Lung cancer is the second most commonly diagnosed cancer in both men and women with an estimated 222,500 new cases expected to be diagnosed in 2017, and an estimated 155,870 deaths, more than any other cancer site (1). A minority of lung cancers (only 16%) are diagnosed at a localized stage which is the only window of disease that is potentially curable with surgery (2). Nonetheless, 5-year survival ranges between 30-50% for lung cancers diagnosed at stage I or II, thus despite early detection and curative resection, a significant proportion of patients will die from recurrent disease within 5 years (1, 2).

Lung cancer, like other cancers is a disease attributed by excessive growth of cells and tissues in the lungs unlike other cancers which occur in different parts. This disorder is typically capable of spreading to other parts of the body and affecting them viciously. Cancers of the lungs are also known as carcinomas. A carcinoma is a strain of cancer that grows from epithelial cells primarily developing from tissues in the inside or outside surfaces of the body. The spread of the uncontrolled growing cells and tissue to the other parts of the body is known as metastasis (Reck et al., 2014). Symptoms of having lung cancer include coughing up blood, panting (short repeated breaths), weight loss, and feeling pain in
