Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood.
Lung cancer is the number one cause of cancer deaths in the both men and women worldwide. Lung cancer has surpassed breast cancer as the most common cause of cancer related deaths in women. Cigarette smoking is the primary risk factor for development of lung cancer. Passive exposure to tobacco smoke can also cause lung cancer. Statistics from the American Cancer Society estimated that 228,000 new cases of lung cancer will be diagnosed and around 159,000 deaths due to lung cancer would occur in 2013. According to the U.S. National Cancer Institute, approximately one out of every fourteen men and women will be diagnosed with cancer of the lung at some point in their lifetime.
Lung cancer is predominantly a disease of the elderly; almost 70 percent of people diagnosed with lung cancer are over 65 years of age, while less than 3 percent of lung cancers occur in people under 45 years of age.
Lung cancers can arise in any part of the lung, but 90 to 95 percent of cancers of the lung are thought to arise from the epithelial cells, the cells lining the larger and smaller airways (bronchi and bronchioles); for this reason, lung cancers are sometimes called bronchogenic cancers or bronchogenic carcinomas. Cancers can also arise from the pleura (called
Funderburk 2 mesotheliomas) or rarely from supporting tissues within the lungs.
There are two major types of lung cancer, which are non-small cell lu...

...because doctors tend not to find the disease until it is at an advanced stage. Five-year survival is 40 to 50 percent for early stage lung cancer, but only 1 to 5 percent in advanced, inoperable lung cancer. Lung cancer survival rate (16.3%) is lower than many other leading cancer sites, such as the colon (65.2%), breast (90.0%) and prostate (99.9%). The five-year survival rate for lung cancer is 52.6% for cases detected when the disease is still localized (within the lungs). However, only 15% of lung cancer cases are diagnosed at an early stage. For distant tumors, that are spread to other organs, the five-year survival rate is only 3.5%. Over half of people with lung cancer die within one year of being diagnosed.

However, other forms of treatment may also depend much on the type of lung cancer that is being treated and it's staging. Be it the more rapid growing Small Cell Lung Cancer (SCLC) that makes up for between 10% - 15% of all diagnosed cases, or the more common and slower growing Non Small Cell Lung Cancer (NSCLC).
In addition to being responsible for 87% of lung cancers, smoking is also associated with cancers of the mouth, pharynx, larynx, esophagus, pancreas, uterine cervix, kidney, and bladder. Smoking accounts for at least 29% of all cancer deaths, is a major cause of heart disease, and is associated with conditions ranging from colds and gastric ulcers to chronic bronchitis, emphysema, and cerebrovascular disease. Women have a better chance in getting lung cancer then men do. This year the disease will kill 68,000 women in the United States, more than one and a half times as many as breast cancer. Even if a woman smoked for awhile and quit, her chances are much greater then a man that smoked 2 times longer then the woman did.
There are more than a million people suffer from cancer in the United States every day. Lung cancer is not the only type of cancer but it affects many people and families every day. Lung cancer makes the lives of its patients and the families. Lung cancer is one of the deadliest types of cancer and also one of the most common. Hundreds of thousands of people get diagnosed with lung cancer every year in just the United States. Also close to just as many people die from lung cancer in the US every year. I am going to talk about lung cancer and what it is, how to lower your risk of getting it, statistics of it, and the research and treatment of it.
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.
Likewise, lung cancer affects people who have never smoked due to the presence of radon and household pollutants. Radon has contributed to 10% of all lung cancer deaths and is considered second to smoking. There is no way to predict who will get cancer, but inherited genetic risk factors make some people more vulnerable to carcinogenic exposures than others. Lung cancer starts whenever there is an uncontrolled growth of abnormal tissue cells that affect the normal function within the lungs. As these abnormal cells grow they form tumors which can block the oxygen exchange within the body. (Lungcancer.org, 2014).
...agnosed at a later stage, most people die within two years of diagnosis and treatment.
When people hear the word cancer, they automatically think death. Worldwide cancer is the leading cause of death. Cancer is also the second leading cause of death in the United States. One out of every four deaths in the United States is due to cancer. In the year 2012 1.9 million deaths were caused by lung cancer, 745,000 deaths were caused by liver cancer, 723,000 deaths were caused by stomach cancer, 694,000 deaths were caused by colorectal cancer, 521,000 deaths were caused by breast cancer, and 400,000 deaths were caused by esophageal cancer. These cancers are also the main types of cancers.
Lung cancer has been around for hundreds of years. Lung cancer is also the most common cancer. Death is almost absolute if not caught in its early stages. Lung cancer is hard to find because there aren’t symptoms in the early stages. Lung cancer found early enough can be stopped before it spread to other parts of your body. This isn’t definite because cancer can be dormant until later in life and it can be worse than before. Lung cancer can be avoided if you if you make the right choices and take right
Lung cancer dates back to 1761 when it was called disease. In 1878 only 1% of the populations were thought to have it. When the 1900s came by that number rose to 15%. There was only 374 case filed by 1912. It wasn’t until 1929 when smoking became a factor in lung cancer. Fritz Lickint was the first person to tell the public about the dangers of smoking that which went into a campaign act to tell worldwide about the dangers of smoking.
Smoking causes many other types of cancer, including cancers of the throat, mouth, nasal cavity, esophagus, stomach, pancreas, kidney, bladder, and cervix, and even leukemia has been found linked to smoking. Also, people who smoke are up to six times more likely to suffer a heart attack than nonsmokers, and the risk increases with the number of cigarettes smoked. Smoking also causes most cases of chronic obstructive lung disease. Also, approximately 49,400 deaths have been due to exposure to secondhand smoke. 3,000 nonsmoking adults die of diseases caused by exposure to second-hand smoke every year.
As most of you know, smoking is bad for your health, but what some of you might not know is that you don’t actually have to smoke to be harmed by smoking. Lung cancer, which is the leading cause of cancer deaths in men and women, is mainly caused by cigarette smoking. Secondhand smoking causes approximately 2 percent of lung cancer deaths each year. It causes respiratory disease, Sudden Infant Death Syndrome (SIDS), middle ear disease, and asthma attacks in children.
Cancer develops when cells in a part of the body begin to grow out of
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 ...
This represents 4.0% of all male 1.8% of female hospitalisations respectively. The epidemiologic evidence and the corresponding biological understanding of respiratory cancer have supported the conclusion that smoking causes lung cancer. It is well documented that cigarette smoke: · is the major cause of lung cancer (primary carcinoma of the lung). · is a cause of heart disease, chronic lung disease, and oesophageal cancer.
Approximately one in two lifetime smokers will die from their habit. Half of these deaths will occur in middle age. The most common of the diseases caused by smoking is cancer, of course. Not only is it a cause of lung cancer, but cancer of the larynx, and the esophagus, and it contributes to the development of cancers of the bladder, pancreas, and kidney. Lung cancer comes from the tar in the cigarettes.
