General information on lung cancer
Lung cancer or cancer of the lung, is one of the most common forms of cancer today. This is one of the most common causes of cancer mortality in the United States today. In the United States, another form of cancer that is becoming more common breast cancer is the development of malignant breast tissue. Breast cancer is especially for women, although this does not mean that people immune. A small percentageEven men fall ill with breast cancer. The numbers are small, 1 man with breast cancer from 100 women with him, but it exists. However, there is a big difference between breast cancer and lung cancer. You can see the symptoms of breast cancer at an early stage, while recognized in the case of lung cancer, early symptoms, especially since they correspond to symptoms of discomfort than others. In this article we will talk about lung cancer.
A person must suffer from the lungcancer when a growth of malignant cancer cells is detected in the lungs. Depending on the stage at which lung cancer is detected, it can be classified as being in the:
o Early stages
o Mid-stages
o Advanced stages
Today, there is a vast amount of information on lung cancer available. Patients or relatives of patients can access information over the Internet, which has an almost limitless number of websites dedicated to different aspects of lung cancer – types, causes, Symptoms, diagnosis, treatment, etc. For example, if you want the United Kingdom and information about lung cancer research, facilities, etc. in your country, you can simply connect to the website of Cancer Research UK, the information of United Kingdom cancer and love to collect what you want from your site.
Previously, treatment of lung cancer has not been easy, what to do, because of the large amount of expenditure in the form of medical expenses, hospital bills, etc. remains, however,Today, with the availability of insurance, things have become easier. Insurance lung cancer is easy, such as insurance, other forms of cancer.
Types of lung cancer
The two main types of lung cancer, there is today. Both are seen in the epithelial cells of the lung. They are:
or non-small lung cancer cells (SLCC)
Or non-small cell lung cancer
There is another type, called mixed small cell / large cell lung cancer. In this type there are two types ofCells in the tumor tissue.
Besides these two types, there is another form of an area known as mesothelioma or lung cancer, mesothelioma, or cancer of the mesothelium. However, this is not considered a primary form of lung cancer, as the area of destination is not the lung, but the pleural membrane of the lungs.
Small Cell Lung Cancer
This is the rarest of the two basic types of lung cancer. Uno su cinque pazienti con carcinoma polmonare a piccole cellule soffronoLung Cancer.
Non-Small Cell Lung Cancer
Non-small lung cancer cells, or non-small lung cancer is the most common of the two types of lung cancer. Four of five patients with lung cancer suffer from this type of cancer.
Classified according to cell type / area in which cancer cells proliferate in the lungs and non-cancer non-small cell lung into three types. They are:
or squamous cell carcinoma
or adenocarcinoma
Or large cellCarcinoma
O Bronchioalveolar carcinoma (BAC)
Squamous
This is the most common form of lung cancer. Occurs in cells, which the airways in the lungs. This form of cancer occurs mainly due to nicotine intake from smoking.
Adenocarcinoma
This form of cancer is seen in mucous cells in the airways in the lungs.
Large tumor
This is also called undifferentiated lung cancer. In large cell carcinoma, theProliferating cells are seen around and much larger than the cells of adenocarcinoma or squamous cell carcinoma.
Bronchioalveolar carcinoma (BAC)
This form of cancer is seen in the bronchioalveolar region of the lung.
What causes lung cancer?
The main cause of lung cancer is exposure to tobacco. This is mainly due to smoking. About 80% of patients with lung cancer are smokers. Smokers can-smokers, smokers, cigar or pipe, no matter. Risk ofLung cancer is the same in all three cases.
A person can inhale smoke directly. A person can also inhale smoke or unintentionally. Smoking is also known as passive smoking. ETS is composed of two types:
Or Mainstream – This is the smoke exhaled by the smoker, and is equal to over 50% of all the smoke.
Sidestream or – This is the smoke from the burning end of a cigarette / pipe / cigar / hookah.
The passive smokers are at a highPossibility of developing lung cancer. The capabilities of the passive / secondary smoking to lung cancer is 30% higher than for people who do not inhale the smoke from both active and passive.
However, there were also cases of total non-smokers were not affected by lung cancer. This suggests that smoking is not the only cause of lung cancer. And 'the main cause, yes, but not necessarily the only cause. Here are some of the other causes of lung cancer:
Or AirPollution
or inhalation of asbestos fibers
or exposure to radon, a radioactive substance formed by the extraction of uranium
or inhalation of smoke through the smoking of marijuana
or exposure of thoracic radiotherapy in the treatment of cancer
O hereditary reasons
or presence of arsenic in drinking water
diet or low in fruit and vegetables (this increases the risk of lung cancer in smokers)
A combination of exposure to tobacco withone of these sources increases the likelihood of a person suffering from lung cancer.
Lung Cancer Symptoms
The following are some of the most common symptoms of lung cancer. Manifests as a rule, not the beginning. Even if they do, they are usually mistaken for other diseases. These symptoms are:
or persistent cough
or reddish brown or muddy spit
or loss of breath
or loss of appetite
or persistent or recurrent infections of the bronchiSection
or hoarseness of voice
O Re-extremis
In its next phase advanced when metastasis to the lung, the symptoms are:
or numbness in the arms or legs
Or look jaundiced
growths or tumors near the skin surface
Or seizures
bone pain or
O Dizziness
Lung Cancer Detection and Diagnosis
It can be seen very rarely in a position of lung cancer at an early stage. There are no specific symptoms of early stages ofLung Cancer. This is one of the reasons why lung cancer is usually detected at later stages.
The use of a suitable technique for screening would greatly increase the likelihood of lung cancer early. However, this technique is not adequate and effective screening for completion. Research to see if we can be quickly made. Cried now, a new technique, spiral CT appears to be the best option for early diagnosis.
After lung cancer has been detected, the next stepdetermine the stage is inside This is done using the AJCC system. Roman numerals are used for different stages of lung cancer, the numbers 0 through IV to highlight it. Sometimes the steps are are further divided into Substage, with denotations A and B. The general rule, the lower the denomination, the less severe the condition.
Lung Cancer Treatment
Treatment options for cancer of the lung are generally the same options as prostate cancer or treatment of colon cancer treatment options. What Isay is that all forms of cancer have the same treatment options. However, tests of lung cancer may be different tests. Standard treatment options for lung cancer are:
OR Surgery
Or radiotherapy
or chemotherapy
What matters is the combination of methods is used. The most serious is the cancer, the probability that many different treatment options will be used simultaneously, or afterother.
