Lung Cancer: The Most Significant Cause Of Death

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.

What are lung cancers? Lung cancers are the abnormal cells which grow in uncontrolled manner in one or both lungs. They do not function as normal lung cells and do not develop into healthy lung tissue. The abnormal cells can grow, form tumours and interfere with the normal functions of the lung (Lungcancer.org, 2015). Lung cancers can be divided into two major types, namely non-small cell lung cancers (NSCLC) and small cell lung cancers (SCLC). NSCLC can be further classified into three main subtypes, namely adenocarcinoma, squamous-cell carcinoma and large-cell carcinoma (Longo & Harrison, 2012). Lung cancers can be diagnosed by chest X-ray, computerised tomography (CT) scan, positron emission tomography-computerised tomography (PET-CT) scan, bronchoscopy and biopsy (Nhs.uk, 2015). Unfortunately, lung cancers are often diagnosed at the later stages. This is due to the unrecognisable symptoms and warning signs at the earlier stages. NSCLC are often diagnosed at stage IV which accounts for 30-40% of cases whereas 60% of SCLC is diagnosed at stage IV. Lung cancer usually originates from the cells lining the bronchi, bronchioles and alveoli. Carcinogens especially tobacco smoke will alter the gene expression of the normal human lung cells, resulting in cell mutation. The proto-oncogenes will be converted to mutated form, oncogenes. Mutation leads to the decreased expression of the tumour suppressor genes. This results in uncontrolled cell proliferation, cell

     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.

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.

However, there are stages in the lives of all humans when the body finds itself in a position where it is no longer able to defend itself against ailments and diseases and eventually may even lose the battle. One such disease which claims many lives every year in this manner is Cancer. So far so, there has been no cure for Cancer but some medicines and treatments are now available which can slow down and in some cases can even alter the effects of Cancer, depending on the stage at which the disease is at that moment. For this paper however we would concentrate on Lung Cancer and its effects.

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.

Cancer is the second largest cause of death in the United States of America, overall, according to the CDC, clocking in at around 575,691 lives in 2013 alone. Countless people have been affected or know someone who has been affected by cancer, and the search for a cure has been raging on for decades. Renal cancers, or cancer of the kidneys, the two bean shaped organs located to the right and left adjacent to a person’s spine, is the fifth most common form of cancer within the United States, affecting too many, too often. Often overshadowed by the greater publicized cancers, this often deadly disease’s information is not as widely known to the public as it should be to help combat this harmful cancer, and help those who are harmed by it.

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.

There are over 14 million cancer victims currently living in the United States. There are over 1,500,000 new cases of cancer that occur every year. Cancer is the number two cause of death in the United States just behind heart disease. There are over 500,000 cancer related deaths in the nation each year. Lung and bronchus cancer are the leading killers with over 150,000 deaths a year. Prostate cancer is the most diagnosed cancer for males with over 220,000 cases a year. For females, breast cancer is the most diagnosed form of cancer with over 230,000 cases a year. These statistics were pulled from www.cancer.org. Current trends suggest that these numbers may continue along their present rate but over time improved treatments will shift the

Every year many people of different ages suffer and die worldwide from different types of cancers. An estimate made by the American Cancer society states that, in the US alone, in 2014 cancer killed 585,720 and lung cancer was responsible of 159,260 deaths (Deadliest Cancer Coalition, 2014). Lung cancer has become the leading killer cancer and finding better ways to treat it has become a priority for many researchers.

Cancer is another leading cause of death in America. As I stated before in previous post, the best way to prevent any disease is to follow a healthy lifestyle that includes, performing some physical activities, eating a healthy diet, and tobacco free. Unfortunately a lot of us don’t make the effort to live a healthy lifestyle. As stated in the video by Dr. Jeff, healthy eating habit is a major way to prevent cancer. Another way is performing physical activities almost every day. Some other ways to prevent cancer include, no tobacco use. Smoking has been linked to various types of cancer including cancer of the lung, mouth, throat; this is a habit that people should definitely

Lung cancer is a tumor that affects either one or both of the lungs.A primary cancer begins in the lungs and a secondary cancer begins in another place in the body and makes its way up towards the lungs. Lung cancer is the 5th most common cancer. In Australia 59% of males were diagnosed were as 41% of Australian females were diagnosed.

According to a paper published by the Center for Diseases and Control, Lung Cancer has the highest mortality rate in the US than any other cancer type. In 2011, about 156,953 people died from the disease as about 207,000 cases of ailing lung cancer patients were diagnosed that year. This number is set to see an increase over the years if adequate care in research is not given .Song described Lung cancer, as Non-Small Cell Lung Cancer (NSCLC) and Small Cell Lung Cancer (SCLC) with the former being responsible for about 85% of diagnosis cases and deaths reported each year. The most common types of NSCLC include adenocarcinomas, large cell carcinomas, and squamous cell carcinomas and as expected, most of these NSCLC types are related to smoking. However, adenocarcinomas have been found in patients who never smoked. Common but inadequate ways of NSCLC treatment include surgery, radiation therapy , and chemotherapy (Witschi , 2001) but the most effective form of NSCLC treatment has been known to be targeted therapies (Nguyen et al. , 2011) . This research invention has taken cancer treatment to another level because of the specificity of the drug inhibitors used to target carcinomas, or protein kinases that involve in pathways of the cancer. Adequate research has led to efficient modifications to use of targeted-therapies for specific fusion genes that code for oncogenes and kinesin genes i.e the Kinesin Family 5B gene and the RET (Rearranged during Transcription). Song also

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%.

When someone says the word “disease” or “illness” the most common association with these words are Cancer. Cancer is so frighteningly common that it is expected by The American Cancer Society to have 564,800 people die of cancer this year which is a little more than 1,500 people a day. Cancer is the second leading cause of death. With these statistics to back up Cancer one will see walks supporting cancer, media discussing possible new found cures, nfl football players wearing pink to support breast cancer awareness, the Susan G. Komen foundation and so many other big foundations raising millions of dollars towards a cure. Where are the walks or large foundations to raise awareness of diseases for psychosis such as Schizophrenia? Schizophrenia
