The Leading Cause Of Lung Cancer

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.

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.

A norm has been broken and has effected my family. My grandpa, Lewis Wayne, passed away October 11, 2016 at the age of 89. His death had caused many of broken norms throughout his life and even toward his last days that my family had grown so use to seeing. My grandpa was a great, hard working man that could never fail to make you laugh. Unfortunately, he was diagnosed with skin cancer in October of 2014. As a family we chose for him to receive radiation/chemo and fight the cancer. He began chemo in February 2015. During his rounds of treatment, there had been shown an amount of reduction. Later in the year of 2015, they had found that the cancer came back and even grew, so he began radiation for 5 days a week for 5 weeks total.

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).

Lung cancer occurs due to cells in a person’s lungs that multiple at a rapid pace, which form a malignant tumor. These tumors in the lungs take away important necessities such as oxygen, and nutrients; diminishes the ability of the tissue to properly function. One of the most type of common lung cancers is Adenocarcinoma, which make up to forty percent of these cases. Smoking is the primary reason for Americans to be diagnosed with lung cancer, with a cigarette containing more than 4,000 chemicals that have permanent damage to the lungs causing long term effects (Conrad 2016).

Lung cancer is one of the leading causes of death not only in the United States of America but globally.1 According to the World Health Organization 8.2 million deaths in 2012 were cancer related and of those deaths, 1.59 million were due specifically to lung cancer.2 In 2014, there was a staggering 224,210 new reported cases of lung cancer in the United States alone. The 5-year relative survival has a 49% to 2% variability depending on the type of lung cancer, stage, and location. The two major types of lung cancer are Non-small cell lung cancer (NSCL), which consists of 85% lung cancers, and small cell lung cancer (SCLC), which makes up the other 15% of lung cancers. NSCL is an epithelial lung cancer that is histologically comprised of adenocarcinoma, large cell carcinoma, and squamous cell carcinoma.1 Both NSCL and SCLC are insidious in nature and the presentation will usually be vague or nonspecific and include the following symptoms: cough, shortness of breath, fatigue, weight loss, recurrent infections, coughing up blood, hoarseness, and wheezing.

About a year after being diagnosed, his doctor told him that he was cancer free. He was so happy; his face was all smiles. I had never seen him so happy in his entire life. It was such a beautiful sight seeing my old mans face that lit up, he told everyone that he was cancer free. I was so proud of my father for being that strong, cancer couldn't even bring him down.

Over decades, lung cancer globally continues to be the leading killer in both genders. In the United States, smoking is responsible for 90% lung cancer deaths in men and about 80% in women. About 15 decades ago, lung cancer was not considered as the leading killer because it was an extremely rare disease about 1% in total of cancer cases. However, by the year 1927, the percentage increased into 14%. During World War I, many soldiers and civilians started smoking to release stress. Eventually, that made the lung cancer rate and smoking addiction in the population started to increase. In a research that published in 2001, lung cancer annually kills over one million people worldwide (Witschi, 2001). The death rate, which caused by lung cancer,

In 2010, doctors diagnosed my father with a rare form of cancer with dismal survival rates and gave him nineteen months to live. As a father of three, he wanted to be the best father he could to my siblings and I for as long as possible.

Lung Cancer is a family crushing illness. I can relate to this illness because my mother passed away a year ago from this. You can be acquire Lung Cancer in many ways. Ether from doing something you were not supposed to do or just in your genes. (According to the Editorial Staff at Healthcommunities.com 2015) “Lung cancer is a disease caused by the rapid growth and division of cells that make up the lungs.” There are many causes of Lung Cancer. Some causes can relate to a higher risk of Lung Cancer. The risk in the workplace is very prominent. As well as the smoke of cigarettes. The location where you live can also be a critical factor.

Cancer has touched nearly every American, either directly or through a loved one. Cancer develops when human cells begin to grow out of control and continuously produce new cells. Cancer remains one of the leading causes of death globally, and treatment is often time-consuming and costly.1 Treatments include surgery, chemotherapy, radiation, immunotherapy, hormones and heat.1 Cannabis is now considered to be a successful aid to these treatment methods. Cannabis contains approximately 85 known types of cannabinoids which consist of active chemicals that create a drug like effects within the human body. In studies conducted by the American Cancer Society, it was discovered that cannabis was helpful in treating nausea and vomiting, often caused

Smoking cigarettes is the leading cause of preventable deaths worldwide, and roughly 1,300 deaths are reported every day from tobacco use. According to the Centers for Disease Control & Prevention, smoking cigarettes increases the chance of a stroke by four times. Since there are so many chemicals rolled up into one cigarette, there’s a greater chance of getting cancer essentially anywhere. Smoking is the leading cause of cancer and cancer related deaths. From smoking cigarettes, you can get cancer anywhere that a cigarette could affect you, not just the major ones like cancer of the mouth, lungs, and throat that are said to be most common in smokers. Cancer is more common in people who tend to smoke on a regular basis because of what cigarettes are made of and how they affect the body (Astor).

Lung cancer is a severe health issue around the world. Worldwide there is a lot of people who have lung cancer, that are not just in the USA. Also, there's a lot of different ways you can get lung cancer not just from smoking. But, other than that lung cancer is the most severe cancer around the world.
