Lung Cancer Research Paper

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

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.

Scientists are sure there are many more they just have not yet been diagnosed. The cancers that are most common in women are breast cancer and cancer of the uterus. The cancers that are most common in men are lung cancer, prostate cancer, and colon cancer. Lung cancer kills more than 50,000 men a year. More men are likely to get lung cancer because in general men smoke more than women. Along with these leading cancers among women and men there are several other cancers that are common in both. Cancers of the colon, rectum, and large intestine kill more than 45,000 Americans a year (Altman and Sang 78). With numbers like that a person may begin to wonder if anyone survives the cancer

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.

Everybody is at hazard for developing cancer; however way of life changes, for example, stopping smoking and diminishing liquor admission could build a man's possibility of not building up a few tumors. Likewise, sound living and dietary decisions can also ensure that should a person get cancer they are more ready to battle it. It is additionally essential to see your doctor for examinations all the time keeping in mind the end goal to guarantee that legitimate testing should be possible if an issue is

Name the cell-types that define carcinomas, sarcomas, lymphomas, and leukemia’s. Which type is most common?

While there are several biological factors that have the ability to lead to cancer, genetics is the most currently researched. A study done by Bharaj, Scorilas, Giai and

Cervical Cancer is the second most common cancer for women yet it is the most common cancer of the reproductive system. According to the CDC in 2010 11,818 women in the United States were diagnosed with cervical cancer and 3,939 women in the United States died from cervical cancer. The most common type is squamous cell carcinoma. Human papilloma virus, otherwise known as HPV, is known to cause cervical abnormalities and has been linked to cervical cancer.

- There are different kinds of Cancers that can be caused by many different factors.

A malignant neoplasm is the medical terminology for Cancer, there are many types of cancers, however, they all are comprised of unregulated cells that show growth or a change. These cells that are cancerous, grow at a hasty rate and will take over other parts of the body, whether being another organ or tissue surrounding the compromised body part. This can also involve the lymph nodes, as well as travel through the bloodstream. There are many influences that contribute to the chance of developing cancers, some of these factors include tobacco use, being overweight and not physically active, exposures to chemicals, and poor nutrition and dietary selections, ones with mutagens in foods, continued or excessive consumption of alcohol, eating foods which are high in fats, and red meat just to name of few. Other types of cancer may be factored by family history, known as a genetic risk, as well as certain viruses that

1. Light-colored skin and a history of sun exposure is the main cause of this type of cancer. Men are affected more often than women.

One thing I learned in researching cancer is that in order for cancer to appear in our body it has to avoid being detected by our immune system. The cancer cells have to avoid being detected by the immune system because if they are detected the immune system will try and fight off the abnormality. If your immune system does not detect the abnormality in cells, the cancer cells will grow and reproduce causing cancer to spread rapidly. The cancer cells that are not detected they can create colonies and spread rapidly.

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

Cancer is abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. The common cancer that people receive are, lung, skin, liver, colon, and breast cancers. Most cancers are treatable in the amount of time it has been diagnosis. The causes of cancer

Cancer is one of the leading causes of morbidity and mortality worldwide, with approximately 14 million new cases in 2012.2 The amount of new cases is expected to rise by about 70% over the next 2 decades. Cancer which causes nearly 1 in 6 deaths, is the second leading cause of death globally, and was responsible for 8.8 million deaths in 2015. Approximately 70% of deaths from cancer occur in low- and middle-income countries. In 2012 about 14.1 million new cases of cancer occurred globally (not including skin cancer other than melanoma).3 The most common types of cancer in males are lung cancer, prostate cancer, colorectal cancer and stomach cancer.
