Detecting the Signs and Symptoms of Lung Cancer Essay

Some symptoms of lung cancer are chronic cough, chest pain, hoarseness, wheezing, swelling in the face and neck, weight loss, fever, loss of appetite, and shortness of breath.

Lung cancer has multiple ways of impacting a body. This depends on the stage of lung cancer and when it becomes diagnosed. At early stages, lung cancer patients are often unaware that they have the disease. As the disease becomes more advanced, variable symptoms can develop. They often present with respiratory symptoms such as cough, shortness of breath, or blood with coughing. Common places

There are two types of lung cancer one being small cell lung cancer which occurs in heavy smokers. The other is non-small cell lung cancer thus including squamous cell carcinoma, adenocarcinoma and large cell carcinoma.

In 2015, 221,000 new cases of lung cancer will be diagnosed out of these cases. An estimated (86,380 in men and 71,660 women) will not survive this disease. Lung cancer is the leading cause of death out of all cancerous circumstances far exceeding that of the colon, breast, and prostate combined. As a result of the final decision made earlier this year by the Centers for Medicare and Medicaid Services (CMS) to cover lung cancer screening with low-dose CT More men and women are expected to be diagnosed with lung cancer.

Lung cancer is one of the most common types of cancer in the world. There are a variety of causes for this particular cancer, the most common one being smoking, or anything related to tobacco. What smoking does is damage the cells in the lungs. When you then inhale the smoke, the cancer-causing substances in the smoke begin to affect the lung tissue. Your body can at first naturally fix the damage, however if the smoking continues, the cells will continue to suffer and behave abnormally, which is when the cancer begins to take over. As one would guess, smoking directly has a much higher risk-rate than not smoking. There is however something called passive (second-hand smoking), in which case being around a heavy smoker can actually have similar

Affecting more than 85% of lung cancer patients, there are more subtypes of non-small cell lung cancer. In non-small cell lung cancer (NSCLC), smoking causes about 90% of the lung cancers diagnosed. The risk mainly depends on how often and how much you smoked. Breathing in secondhand smoke raises the risk for developing lung cancer. Research shows that smoking marijuana may help the cancer cells grow even more. However, there is no direct link between smoking marijuana and developing lung cancer. Being constantly exposed to high levels of air pollution and drinking water that contains a high level of arsenic can increase your risk for lung cancer. Also, a history of radiation therapy to the lungs increases your risk for lung cancer (NLM). Early lung cancer may not show any symptoms, but some are: chest pain, cough that does not go away, coughing up blood, fatigue, shortness of breath, and wheezing. In later stages of NSCLC is: bone pain or tenderness (NLM). 39% of NSCLC occur in the small intestine. Obviously, non-small cell cancer mainly occurs in the digestive system and intestinal tracts of humans

Lung cancer mainly occurs in older people, but may occur in younger people as well. Many people who are diagnosed with lung cancer do not live passed the 5 year survival rate. People with stage 4 who make it passed the one year mark with stage 4 lung cancer often lucky. There are several lung cancer risks. Many people may experience a cough that does not go away or gets worse. The person may have chest pain that is often worse when taking a deep breath. The cough and chest pain are often mistaken for pneumonia. The person may experience weight loss and loss of appetite. In the late stages the person may have shortness of breath and feel tired or weak. Lung cancer could be diagnosed in a variety of ways. Lung cancer is often found when the person is having signs or symptoms. X-rays, magnetic fields, sound waves, or radioactive substances create pictures of the inside of your body. Imaging tests may be done for a number of reasons both before and after a diagnosis of lung cancer (cancer.org). X rays may not be able to pick up lung cancer sometimes so it is best to use another imaging test. A cat scan is more likely to show images of a tumor than a chest x

The symptoms of non-small-cell lung cancer is hard to be noticed in the early stages,

The most common symptoms are weigh loss, respiratory difficulties and cough. (Horn, L; Pao W, Johnson DH. Harrison's Principles of Internal Medicine. 18. ed. [S.l.]: McGraw-Hill, 2012. Cap 89.) Lung cancer can be seen on chest radiograph and computed tomography (CT). The diagnosis is confirmed by a biopsy, which is generally accomplished through bronchoscopy or a biopsy guided by CT.

The most common cause of lung cancer is smoking cigarettes. 80% of people who have lung cancer got it from smoking. The longer you smoke cigarettes the better chance of getting lung cancer. Smoking at a young age increases the chance of getting lung cancer more then starting to smoke as an adult. The sooner you quit, the better your life will be. Passive smoking (secondhand smoking) can give you lung cancer if exposed for a long time to it.

The symptoms for lung cancer are a cough that never goes away and having problems breathing when coughing and laughing even having chest pains. Weight loss is another symptom of lung cancer. Lung cancer description is a uncontrolled growth of abnormal cells that start in one or both of the lungs. Sometimes the cells divide rapidly and then form the tumors. As time goes

• Some risk factors for lung cancer are passed down through families. Talk to your health care provider or genetic counselor to learn more about genetic testing for cancer.

Lung cancer is a malignant transformation and growth of the cells of the lung and the airway tissues. It is usually divided into two main types: Small Cell Lung Cancer (SCLC, 15%) and Non-Small Cell Lung Cancer (NSCLC, 85%) with the latter further subdivided into several subtypes such as Squamous, Large Cell, and Adenocarcinoma among other rare subtypes. Each subtype has its own unique growth and spread pattern with some being more aggressive than others. Lung cancer is staged according to the American Joint Committee by the TNM system, where T stands for the size, N for nodal involvement and M for the presence of distant metastases. The knowledge of the lung cancer main types, subtypes and stage, and the presence of specific molecular and genetic signatures, help the clinician determine the treatment approaches be it surgical, radiation, chemotherapy and the combination of, in addition to the appropriate type of chemotherapy.

Lung cancer is one of the most common types of cancer. There are many ways that lung cancer is caused, it can be inherited, you could be exposed to chemicals that damage the cells and tissue in your lungs/air pollution and smoking. Smoking is the main cause of lung cancer as the chemical ‘carcinogens’ damages the cells within your lungs and is pumped out to the other organs in your body.

the most common cause of lung cancer is smoking, 90% of lung cancer cases among men are due to smoking and 80% of lung cancer among women are due to smoking. Smoker men are 23 times more likely to get lung cancer, and smoker women are 13 times more likely to have lung cancer in comparison to nonsmokers (USDHS, 2004). Annually, between 2005 and 2010 lung cancer cases due to smoking are about 130,659, 56.8% of these cases were men, and 43.2% were women (USDHS, 2014). Also, second-hand smokers are at higher risk of developing lung cancer, their chance to develop lung cancer is 20-30% in comparison to people who do not have an exposure to the second-hand smoke (USDHS, 2006). In 2014, the estimated
