Lung cancer and smoking often, have some correlation, but it's not always the case. As lung cancer stages progress, lung cancer symptoms include coughing, wheezing, shortness of breath, and bloody phlegm. Treatment comprises of surgery, chemotherapy, and radiation. Lung cancer has typically no signs in its initial stages. When symptoms of the disease start to resemble, they can introduce hacking, raspy coughing, sometimes with mucus that has blood in it. There are also recurring respiratory infections like bronchitis or pneumonia. Finally, chronic shortness of breath, wheezing, persistent chest pain and inflammation in the neck and face. These problems frequently happen because of blocked breathing ways or because the cancer has reached farther
1. Chemotherapy tends to be the conventional lung cancer treatment used that everyone has heard of. Today it uses a cocktail of over 100 different drugs and works by destroying the cancerous cells and stopping their spread. However, although considered to be an acceptable treatment, it does tend to cause many unwanted side-effects.
Cancer of the lung was nearly nonexistent in the early 1900’s. By the middle of the 20th century an epidemic became apparent throughout the United States and the rest of the world. It is primarily correlated with the widespread abundance of cigarette smoking in the world. The tobacco industry has multiplied its production immediately prior to World War I. There was a typical 20 to 30 year lagging period between the initiation of cigarette smoking and the actual tumor formation in the lungs. Lung cancer is the cancer that originates in the tissues of the lungs. It occurs when cells in the lung start to grow rapidly in an uncontrolled manner. Lung cancer can start anywhere in the lungs and affect any part of the respiratory system. Most of all lung cancer cases start in the lining of the bronchi (health-cares.net, 2005). It is the leading cause of all cancer deaths in the world. During this time the tobacco companies would continue to say that cigarette smoking was not addictive and did not cause any type of cancer. Even with all evidence in the world today about tobacco causing cancer, Tobacco companies still remain the most profitable business in the world. Lung cancer is very common in both women and men. Women account for about 40 percent of the lung cancer cases in the world. Women who smoke are more than twice as likely to develop lung cancer as those of men who smoke (Tavor, 2005).
Smoking is the most preventable cause of death in our society. During 1995, approximately 2.1 million people in developed countries died as a result of smoking. One tobacco use is responsible for nearly one in five deaths in the United States. Lung Cancer mortality are about 23 times higher for current male smokers and 13 times higher for current female smokers compared to a lifelong never-smoker.
Diagnosed with lung cancer, now what!? Time to do some research. Lung cancer is the number one cause of deaths in males and females. The causes, diagnosis, and treatment of lung cancer have advanced recently with new technology available to scientists and the medical profession. Lung cancer develops when the cells grow abnormally and tumors form instead of healthy lung tissue. It can take place in one or both lungs, normally the cells that line the air passages. Not all tumors are cancerous, the ones that do not spread are benign tumors. The more tumors that develop in the lungs will cause the lungs to work less efficiently. The metastatic tumors spread to other parts of the body passing through the blood stream or lymphatic system.
According to “Medical News Today” cancer is a disease that is caused by an over growth of anomalous cells on one or more lungs. Cells often go up the air pipes which can cause difficulty to breath. Due to the over production of cells the tissue cells often begin to over produce; which results in tumors. There are two types of tumors: malignant and benign. Malignant tumors are the more dangerous of the two due to its invasive nature; which makes it cancerous. While benign is not invasive in other words non-cancerous. This is why cancer spreads to multiple areas and can be sometimes very difficult to fight. Cancer cells are abnormal not only because of their evasive nature, but also because of its irregular life cycle. Rather than expire like a regular cell, they continuously grow and duplicate which causes the disease to spread. This makes cell abnormal in shape and other qualities; known as a sickle cell. Due to the large growth and reproduction rate of the cells this makes the spreading of the cancer more rapid. Each cancer has specific symptom, for lung cancer the sympto...
The working of the lungs is vital to the human physical structure. They provide the body with oxygen to keep the cells happy and help to maintain homeostasis. There are many carcinogens that cause cancer leading to the lungs not to doing their job. Sometimes the cancer spreads and causes metastases. The patient’s medical diagnosis is malignant neoplasm of the bronchus and lung brain metastases.
Over a hundred years ago lung cancer was considered a very rare disease. Lung cancer is a disease that is known worldwide. Lung cancer is one of the four most common cancer. Lung cancer is detrimental to the Respiratory System and can cause permanent damage. Lung cancer is a tumor that grows in your lungs and it can also spread to other parts of your body. Early stages of lung cancer are hard to detect because it could take about a year for the tumor to grow to the point when you start experiencing symptoms. The most common cause of lung cancer is smoking cigarettes and other tobacco products. There are other causes like secondhand smoke, asbestos, and lung cancer is common in your family.Lung cancer has different risk factors, symptoms,
Smoking is linked to multiple different forms of cancers such as lung, larynx (voice box), nose and sinuses, pharynx (throat), stomach, pancreas, kidney, and bladder to name a few. Lung cancer is the number one cause of death related to cancer for men and women and is very difficult to treat. A person with lung cancer not only has significant pain, but experiences anxiety related to the feeling of not getting enough oxygen. Besides cancer, smoking is linked to multiple other health problems – heart disease, aneurysms, chronic bronchitis, and emphysema. With heart disease, the nicotine in the blood increases the level of adrenaline which leads to an elevation of the blood pressure by causing blood vessels to constrict. This constriction of the blood vessels makes the heart pump harder resulting in an increased heart rate. An aneurysm in the brain can be caused by the hundreds of harmful toxins in cigarette smoke that weaken the wall of the brain’s blood vessels. The weaken blood vessels can rupture leading to a stroke or often death. Chronic bronchitis is caused by the toxic chemicals irritating the lining of the airway and leading to a buildup of mucus. The mucus is a natural
Lung cancer is the most common cancer in the world. There are many ways to attract lung cancer. Many people think that the only way to get cancer is by being a smoker but believe it or not you can get cancer without ever even smoking a cigarette. There also are different forms of lung cancer some are life threatening and others aren’t. My goal is for you to know everything about and or dealing with Lung Cancer by the end of this paper. Throughout this paper I will elaborate on those topics and I will also talk about some of the symptoms, and ways to prevent attracting it, cures and a few more topics.
Due to this, it often takes longer to diagnosis. The one thing providers depend on is the patients’ history. listening to a patient's history, it may lead to getting them screened for lung cancer. A standard screening method is computed tomography (CT scan). High-risk patients are advised to receive this annually especially if they have a long smoking history. This test has shown to reduce death caused by lung cancer by twenty percent. Current guidelines recommend smokers have an annual chest x-ray done, but the literature does not provide information the level of benefit. The sputum test is another way of checking for cancer cells, but this does not have explicit evidence to back it
Cancer is defined as where the abnormal cells are divided without any control and they are able to invade into tissues. At times cancer can be cured right away once it is detected through treatments that the doctor recommends, but at times cancer cannot be cured based on what stage the cancer is at. It is very important that every individual gets a physical check up to see if they are diagnosed or detected with any sort of cancer or disease. There are 100 types of cancers out there, but the type of cancer that I will be focusing on is Lung cancer. One of the controversial issues on a lung cancer is the ...
The treatment for lung cancer depends on what type and what stage the cancer is on. If you have non-small cell lung cancer is treated by having surgery, chemotherapy, radiation therapy, targeted therapy, or with a combination of all these treatments all together. Doctors can use all those treatments to treat non-small cell lung cancer. The treatments that you need to treat small cell lung cancer are with radiation and chemotherapy. (Lung Cancer,
Lung cancer is when a tumor spreads through your lungs; this can spread past your lungs to other parts of your body by metastasis. There are multiple symptoms to show you and other people that you have lung cancer. The can be coughing up blood, fever, bone pain, and having trouble swallowing. Another sign is when the cancer
INTRODUCTION It's a proven fact. Each year more Americans die from lung cancer and other smoking-related diseases than they die from alcohol, drug abuse, car accidents and homicide, combined. Cigarette smoking is a danger to our life and health. It is the leading known cause of lung cancer.
Scientists and health officials have been arguing the detrimental effects smoking has on our health for many years. Smoking can lead to serious complications including asthma, pancreas, lung and stomach cancer due to the large number of carcinogens (cancer causing chemicals) and other various substances added to it. It is a health hazard for both smokers and non-smokers and it is especially harmful to unborn babies. Although smokers claim that it helps them to relax and release stress, the negative aspects of the habit take over the positive. As it has been stressed by the scientists and experts, there are some very severe reasons of smoking but its crucial consequences should also be taken into consideration.
