Lung Cancer : The Most Common Cause Of Cancer

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 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

Causes: The foremost reason for lung cancer is cigarette smoking which causes around 90% of all deaths caused by lung cancer in the world. However, smoking is not the only way to get it. The second most frequent cause of lung cancer is exposure to radon gas, which

Lung cancer happens to be the top cause of deaths in the United States for both genders. It tends to people who smoke are at a higher risks for this type of cancer. Even people who are exposed to secondhand smoke are at risk. Others can get this cancer even if they aren't near smoke at all. Smoke is believed to cause lung cancer because it's damaging the cells that line the lungs. It causes cells to act abnormally.

Among all types of cancer, lung cancer is a very common and highly lethal cancer. Lung cancer is an insidious disease not showing symptoms in its early stages, thus the diagnosis in most cases is done in cases of advanced disease. Shows an increase by 2% year on their worldwide incidence. Mortality from this tumor is very high and the prognosis of this disease is related to the phase where it is diagnosed.

The Lung Cancer is the major of the cancer death. According to the data from Australian government on 2011, it showed the death rate is far higher than other disease, all because its early symptoms are non-evident, that lead to most of the sufferers are often missed the best time for treatment. Lung Cancer occurs when there has the uncontrolled cells growth in the lung tissues, these cells normally lining on the air passages, then forms a tumour which can be small-cell carcinoma or non-small-cell carcinoma. The five year survival rate of the person who with Lung Cancer is less than 14%(EWTERY).

Small cell lung cancer and non-small lung cancer can be differentiated by the biological and histological markers (Vescio, et.al., 1990). Among these two major types, non-small cell lung cancer is responsible for 85% of lung cancer (Lungcancer, 2015). Non-small cell lung cancer can also be divided into 3 common types since their spreading behaviors and microscopic structures are different. Those three are squamous cell carcinoma, large cell carcinoma, and lastly adenocarcinoma (NIH National Cancer Institute, 2015). Among these three, Adenocarcinoma accounts for 40% of NSCLC, and it is known as the most common types of

More people die from lung cancer than prostate cancer, breast cancer and colorectal cancer combined. Approximately 150,000 people in America die from lung cancer each year. Additionally, nearly one-third of cancer deaths are caused by lung cancer.

Lung cancer is the leading cause of cancer-related death in the United States. Cancer develops

Small cell lung cancer is also known as oat cell carcinoma and accounts for about 15% of lung cancers. Oat cell carcinoma usually begins in the bronchi, but spreads quickly and early to the brain. Small cell lung cancer responds to chemotherapy at first, but it becomes more and more defiant to treatment as the disease goes on. It is separated into two groups, extensive stage and limited stage. People are usually already at the extensive stage of the disease when they are first diagnosed. Most cases are found in men (probably because of a hormone reaction) and are due to smoking.

If lung cancer is the number one killer in the United States, one must wonder how it affects other countries around the world. One will find that the United States does not even have the worse statistics of death from lung cancer. Scotland, England, and Finland are the top three, then is the United States in the middle and below us are: Canada, Australia, El Salvador, and Syrian Arab countries. Lung

Lung cancer is a very common malignant disease around the world, which is mainly caused by long-term exposure to tobacco smoke (85% of all cases). [1] It is reported by WHO that, globally in 2012, 1.8 million people suffered from lung cancer, and 1.6 million patients died of lung cancer. [2] In cancer-related death all around the world, lung cancer ranks the top in men and second in women, only after breast cancer. [3] Statistically, 17.4% of lung cancer patients in the United States only have five-year survival after the diagnosis, and the average survival rate is even worse in the developing countries. [4]

Lung cancer begins when cells of the lung become abnormal and begin to grow out of control. As more cancer cells develop, they can form into a tumor and spread to other areas of the body. According to the American Cancer Society, there are two types of lung cancer, which grow and spread differently, one is a small cell lung cancers (SCLC) and the other is a non-small cell lung cancers (NSCLC). Non-small-cell lung cancer refers to all lung cancers that are the not small-cell type, and makes up about 80% of lung cancers. Small-cell lung cancer makes up about 15% of lung cancer; Small-cell lung cancer differs from non-small-cell lung cancer in the fact that, small-cell lung cancer grows rapidly and spreads quickly. About 67% of people who develop small cell lung cancer, will have cancer outside of the lungs by the time of initial diagnosis.

According to 2014 facts smoking tobacco, lung cancer is the leading cause of cancer death in the United States for both men and women and is one of the hardest cancers to treat. In 2014, lung cancer estimated 224,210 new cases that includes 116,000 males and 108,210 females. Total deaths from lung cancers are estimated approximately 159,260 which includes 86,930 males and 72,330 females. Women smokers are 25.7 times more likely than women who never smoked to develop lung cancer. For men smokers, it is 25 times the risk of men who never smoked. Cancer Facts & Figures

Non-small cell lung cancer is the most common and accounts for 85% of lung cancers (nlm.nih.gov).
