Lung cancer is one of the most common cancers.
In fact, it is the most common cancer in the US, with over 220,000 people being diagnosed with it each year.
The number of deaths caused by this disease until about 150,000 years in the U.S. alone.
These are the main reasons why learning the most important things about the condition is essential.
Lung cancer is the transformation of normal cells in the lungs characterized by abnormal cell.
These abnormal cells grow rapidly and uncontrollably to form a malignant tumor.
This happens mostly in the walls of the bronchi.
There are over 20 types of lung cancer, but four have been identified as the most commonly occurring.
These four groups were separated into two non-small cell lung cancer and small cell lung cancer.
The most common kind of non-small cell cancer of the lungs is adenocarcinoma.
Represents about 40% of all cases.
The most typical thing for it is that it is formed in the outer edges of the lungs and in the smaller airways, in particular.
Squamous cell carcinoma is another type of non-small cell lung cancer.
It is responsible for approximately 30% of all cases.
The tumor usually grows in the central bronchi, which are the largest branches of the bronchial tree.
This form of the condition is the easiest to detect and to treat successfully.
The large cell carcinoma affects between 10% and 15% of all patients with lung cancer.
These tumors usually grown in the outer edges of the lungs and tend to spread quickly to nearby tissues and lymph nodes.
Small cell lung cancer is not common, but it's extremely aggressive.
It starts in the central bronchi, but has no noticeable symptoms until the later stages of the tumor development.
In addition, it tends to spread rapidly to other organs and tissues.
Lung cancer is directly linked to smoking and cigarette smoking, in particular.
About 4 of 5 patients are smokers.
It has been estimated that up to 90% of all cases are arising directly from the use of tobacco.
All these facts show that smokers are at higher risk for developing this condition.
Pipe and tobacco smokers as well as passive smokers are also more likely to develop this type of cancer.
The biggest risk is the fact that tobacco contains carcinogens and carcinogenic chemical compounds used.
Asbestos exposure is also correlated to the development of lung cancer.
Fortunately, the use of this material is limited or prohibited in many countries.
The exposure to radiation coming from the decay of radon gas is also a serious risk factor.
About 10% of all cases of the disease are estimated due to this factor.
The presence of specific genes may also increase the risk in some individuals.
About 25% of all people, lung cancer symptoms do not occur.
Despite this, there are some common warning signs associated with the condition.
Coughing up blood is the most disturbing symptom.
Smokers and ex-smokers might start having a new cough that is persistent and untypical for them.
Chest pain and breathing difficulties are more common warning signs.
Having repeated respiratory infections might also signal that you have the condition.
Lung cancer is diagnosed after a series of tests.
The doctor usually performs an x-ray first, after noticing disturbing symptoms.
A CT scan is also performed.
A biopsy is done to confirm the condition.
Further tests are needed to determine the type of lung cancer the patient has.
Lung cancer treatment usually begins with surgery.
Surgeons can remove only the tumor, the tumor with a lung or part of the entire lung.
Cryosurgery, the killing of the tumor by freezing it, is also an option.
The treatment is usually continued with chemotherapy and radiotherapy.
It should be pointed out that number of patients surviving five years after treatment is around 15%.
For this reason, prevention is very important.
The best method for this cancer prevention is not smoking.
If you smoke, stop now, but the risk is automatically started decreasing.
It has been estimated that your risk will be similar to a nonsmoker after 15 years of cessation.
Try to avoid exposure to cigarette smoke.
Take protective measures if you work with dangerous material such as asbestos.
