An Overview of Lung Cancer

Overview of lung cancer

Lung cancer or lung cancer is one of the most common forms of cancer today. It 's a common cause of cancer mortality in the United States today. United States, another form of cancer is increasingly common to have breast cancer, which is the development of malignant tissue in the chest. Breast cancer is seen mostly in women, but that does not mean men are immune. A small percentage of men contract breast cancer. The numbers are small, one man against 100 women with breast cancer, but it is there. But there is a big difference between breast cancer and lung cancer. You can see the signs of breast cancer at an early stage when it comes to symptoms of lung cancer are not detected early, especially because they are symptoms of other, less problems. In this article, we will talk about lung cancer.

A person is said to suffer from lung cancer when the growth of malignant cancer cells are found in the lungs. Depending on the stage where the cancer is discovered, it can be described as:

No early

o Mid-stage

or an advanced stage

Today is a huge amount of information available for lung cancer. Patients or patients' relatives to obtain information on the Internet, which has almost unlimited web pages in different part of the lung cancer - types, causes, symptoms, diagnosis, treatment, etc. For example, a British citizen and want to research data on treatment of lung cancer, installations, etc. in your country, you can connect to the website of Cancer Research UK, the leading cancer charity in the United Kingdom and collect the information you want on them.

Previously, treatment of lung cancer is not an easy thing to do because of the enormous amount of expenditure in the form of medical bills, hospital expenses, etc. But today the availability of insurance, things became easier. Insurance lung cancer is readily available, whether the insurance covers other types of cancer.

Types of lung cancer

There are two main types of lung cancer exist today. Both are seen in lung epithelial cells. They are:

No small cell lung cancer (SLCC)

O non-small cell lung cancer

There is another type called mixed small cell lung cancer cells to large. In this type you can find two types of cells in cancerous tissues.

Besides these two types, there is another form of the surface of the lung, known as mesothelioma or mesothelioma cancer, or cancer of the mesothelium. However, it is not considered a primary form of lung cancer, as its target area is not overlapping in the lungs, but the pleural membrane covering the lungs.

Small cell lung cancer

This is the rarest of the two basic forms of lung cancer. One in five lung cancer patients suffering from lung cancer, small cell.

Non-small cell lung cancer

Non-small cell lung cancer, lung cancer or non-small is more common to have two types of lung cancer. Four of five patients with lung cancer suffer from cancer.



Depending on the type of cells / area in which cancer cells proliferate in the lungs, cancer of non-small cell lung cancer is classified into three types. They are:

or squamous cell carcinoma

or adenocarcinoma

or large cell carcinoma

bronchoalveolar carcinoma (BAC)

Squamous cell carcinoma

This is the most common lung cancer. It occurs in cells that line the airways in the lungs. This type of cancer occurs mainly in nicotine intake through smoking.

Adenocarcinoma

This form of cancer that is observed in the cells lining the airways in the lungs.

Large cell carcinoma

This is also called undifferentiated lung cancer. large cell carcinoma, the proliferating cells are round and much larger than cells of adenocarcinoma or squamous cell carcinoma to see.

bronchoalveolar carcinoma (BAC)

This cancer is considered in the region of the broncho-pulmonary.

What causes lung cancer?

The main cause of lung cancer is exposure to snuff. It is primarily by smoking. About 80% of patients with lung cancer are smokers. Smokers can smoke cigarettes, cigars, snuff or pipe smokers, never mind. The risk of lung cancer is equal in all three cases.

A person can inhale the smoke directly. A person can also inhale secondhand smoke or unintentionally. This smoke is also known as passive smoking. environmental tobacco smoke is of two kinds:

O Mainstream - This is the smoke exhaled by the smoker, and amounting to more than 50% of all secondhand smoke.

No Side Stream - This is the smoke from the burning end of cigarettes / cigars / pipe / hookah.

Passive smokers are also likely to have lung cancer. The chances of passive / secondary lung cancer smoking is greater than 30% of people who do not inhale the smoke, either actively or passively.

However, there have been cases even total non-smokers with lung cancer. This indicates that smoking is not the only cause of lung cancer. Is the main cause, yes, but hardly the only cause. Some other causes of lung cancer:

No Air Pollution

Inhalation of asbestos fibers

No exposure to radon, a radioactive substance to break uranium

No, smoke inhalation of marijuana smoke

No exposure to radiation therapy of the chest wall during cancer treatment

or hereditary reasons

Or the presence of arsenic drinking water

o A diet with low fruit and vegetables (which increases the risk of lung cancer in smokers)

A combination of tobacco exposure with one of these reasons, increases the chances of someone with lung cancer.

The symptoms of lung cancer

Here are some common symptoms of lung cancer. They usually occur in the early stages. Even if they do, they are usually taken for another disease. These symptoms include:

Or persistent cough

No spitting or reddish brown muddy

No loss of breath

No appetite

or persistent or recurrent infections of the bronchial airways

N. hoarseness and voice

No wheezing renewed

After the later stages when lung cancer is said to be a metastasis symptoms include:

Or numbness in the arms or legs

jaundice or

No tumor growth near the skin surface

No attack

No bone pain

O dizziness

Detection of lung cancer and diagnosis

It is very rare to be able to detect lung cancer at an early stage. No specific symptoms of early lung cancer. This is one reason why it is usually detected lung cancer at an advanced stage.

The use of an appropriate screening technique would greatly increase the chances of early detection of lung cancer. However, there is such a complete and correct technique effective screening yet. The research is to see if we can be formulated soon. What now appears a new technique called spiral CT to be the best solution for early detection.

When lung cancer is detected, the next step is to determine the phase, in that, using the AJCC system. Roman numerals are used to mark different stages of lung cancer, numbers from 0 to IV. Sometimes, the phases are then divided into sub-steps, using the denotations A and B. The general rule is that the lower part of the name, the less serious condition.

Lung Cancer

Treatment options for lung cancer are generally the same as the treatment of prostate cancer or treatment against cancer. What I mean is that all forms of cancer the same treatment. However, samples of lung cancer differ from tests for colon cancer. Standard treatment for lung cancer are:

o Surgery

o Radiotherapy

o Chemotherapy
