Cause, Causes And Effects Of Lung Cancer

     Lung cancer is the most common cancer-related cause of death among men and women. Lung cancer can be undetected for many years causing it to become more dangerous and possibly fatal. There is not cure for lung cancer or any cancer, but if detected in an early stage the lung cancer can be detected, treated, and hopefully terminated. There are many new and developing treatments being tested now that may save lives in the future. Through understanding what the lung cancer is, doctors can easily diagnose and assess cancer patients.

A common form of cancer that is very popular today is lung cancer. Lung cancer is a very dangerous form that can cause problems in simple body functions. These simple body functions are short breath and general fatigue. Lung cancer is commonly formed from smokers that has been exposed to that activity for numerous years. Lung cancer can also be spread by being exposed to asbestos or other pollutants. This form of cancer has many risk factors to it. These risk factors are high levels of air pollution, arsenic drinking water, and radon gas. Radon gas is a gas that is highly radioactive and is very sensitive to the body. Once radon is exposed to the body, it has a very high respiration rate which initially divide its radioactive cells- causing more significant damage to the body.

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

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.

Lung cancer is a genetic and acquired disease. Lung cancer is genetic because cancer in general is caused by changes to the genes that control the way our cells function, especially how they grow and divide. All of these changes include mutations in the DNA that makes up our genes. Genetic changes that increase cancer risk can be inherited from our parents, if the changes are presents in germ cells. Which are the reproductive cells of the body, those are the eggs and the sperm. Lung cancer is also acquired because as the result of errors that occur as cells divide a person’s lifetime or exposure to certain chemicals. Some examples of these chemicals are found in tobacco smoke, radiation, UV rays from the sun that damage DNA. “In general, cancer cells have more genetic changes than normal cells. But each person’s cancer has a unique combination of genetic alterations.” Some of these changes may be the result of cancer, rather than the cause. As the cancer continues to grow, additional changes will occur. Even within the same tumor, cancer cells may have different genetic changes.

Lung cancer is the leading cause of cancer-related mortalities in the world. An astounding average of 1.6 million deaths occur due to lung cancer yearly (1). Lung cancer is classified into two types: small cell and non-small cell lung carcinoma (NSCLC), where 85% of lung cancer cases are NSCLC. NSCLC has several different histologic subtypes, some of which are: squamous cell carcinoma, large cell carcinoma, and adenocarcinoma. Of the three, adenocarcinoma accounts for more than 50% of NSCLCs, making it the most common subtype (2).

What is cancer?-Cancer is a disease caused by an uncontrolled division of abnormal cells in a part of the body.Malignant growth or tumor resulting from the division of abnormal cells.Some of the body's cells begin to divide without stopping and spread into surrounding tissue.

According the cancer research UK organization, “the Tobacco was responsible for more than 100 million deaths worldwide in the 20th Century”. (). The World Health Organization has estimated that, if current trends continue, tobacco could cause a billion deaths in the 21st Century. Smoking tobacco may cause cancer such as lung, esophagus, mouth, throat and the main one is lung cancer. Lung cancer starts in the lung. The lungs are a pair of cone-shaped breathing organs inside the chest. They bring oxygen into the body when breathing in and send carbon dioxide out when breathing out. The two main types of lung cancer are non-small cell lung cancer and small cell lung cancer. The types are based on the way the cells look under a microscope. Non-small cell lung cancer is much more common than small cell lung cancer. Non-small cell lung cancer is the most common type of lung cancer. About 85% of lung cancers are non-small cell lung cancers. Squamous cell carcinoma, adenocarcinoma, and large cell carcinoma are all subtypes of non-small cell lung cancer. The second type is the small cell lung cancer which is also called oat cell cancer. About 10%-15% of lung cancers are small cell lung cancers. This type of lung cancer tends to spread quicker than the others. The third type is Lung Carcinoid Tumor. Fewer than 5% of lung cancers are lung carcinoid tumors. They are also sometimes called lung neuroendocrine tumors. Most of

Lung cancer is a type of cancer that starts on the cells lining the bronchi and other parts of the lungs. Lung cancer claims more lives than colon, prostate, ovarian, and breast cancer combined. It is thought that lung cancer starts in areas of pre-cancerous changes in the lungs. It then will develop into lung cancer over time. There are 2 main types of lung cancer, small cell and non-small cell lung cancer. Non-small cell lung cancer is the most common type of lung cancer. Symptoms of lung cancer do not usually appear until a later stage of lung cancer. Some

Lung cancer is an uncontrollable disease in the lung. Many people die from this cancer because most of it has spread to other parts of the body by the time the symptoms start to show. The definition of lung cancer is the appearance of malignant tumors in

Cancer is the leading cause of death in the world. An astounding average of 1.6 million deaths occur due to lung cancer every year, making it the most common type of cancer worldwide (1). Lung cancer is broadly classified into two types: small cell and non-small cell lung carcinoma (NSCLC). 85% of all lung cancer cases are NSCLC. NSCLC has several different histologic subtypes, some of which are: squamous cell carcinoma, large cell carcinoma, and adenocarcinoma. Of the three, adenocarcinoma accounts for more than 50% of all NSCLC cases, making it the most common subtype of NSCLC (2).

Cancer is the disease caused by an uncontrolled division of cells in a part of the body. Specifically, lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. Since these cells are abnormal, they do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, these abnormal cells could possibly form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood. In both men and women, lung cancer is the second most common cancer and is the leading cause of cancer death.

Lung cancer can be divided into two different types, small cell lung cancer and non-small cell lung cancer. Small cell lung cancer is the least common type and is mostly found in those that smoke a lot. It is also the most deadly because of the rapid growth it exhibits. Non-small cell lung cancer is a general term for many different types of lung cancer. These types are: squamous cell carcinoma, adenocarcinoma and large cell carcinoma. (Mayo Clinic, 2015) Lung cancer solely attacks the lungs but could metastasize further.

Lung cancer is a deadly class of disease that is specifically composed of uncontrolled cell growth in the pulmonary extremities of the body (Crosta. 2009). When left untreated, the abnormal lung tissue eventually develops into life-threatening tumors (Crosta, 2009). Lung cancer is a disease that is particularly caused by smoking, nonetheless there are cases where it is simply developed naturally. The disease can severely harm the health of an individual over the course of years. In addition, researchers have determined that lung cancer is the leading cause of cancer deaths among both men and women (Mayo Clinic Staff, 2014). As of today, about 210,828 people in the United States have been diagnosed with lung cancer (CDC, 2015). In 2012, about
