What Type of Lung Cancer is Caused by Asbestos?

lung cancer is caused by asbestos via thinkearth.wordpress.com

Of the lethal diseases asbestos exposure can cause mesothelioma which is a cancer of the

pleura or membrane surrounding the lungs is probably the most commonly known yet asbestos

 can also cause lung cancer such as bronchogenic carcinoma or Edna carcinoma a cancer of the lung tissue itself diagnosing any asbestos-related disease is challenging symptoms develop

gradually are not specific and can mimic other conditions or diseases even when the physician

is aware of asbestos exposure or the patient has a history of asbestosis which leads to asbestos

lung cancer in approximately one out of every seven cases the diagnosis must rule out other

 possibilities a thorough and accurate medical history is always the first step documenting

medical conditions work history and family medical history and taking into consideration

cultural and environmental factors a general physical exam follows including listening with a stethoscope for labored breathing wheezing or fluid in the lungs sometimes laboratory tests

such as a complete blood count may be ordered when a physician suspects a lung condition he

 will usually prescribe a pulmonary function test and chest x-ray a pulmonary function test

which measures lung function shows if the patient's breathing ability is what would be

 considered normal for a person of the patient's age physical condition and ethnic background

 the chest x-ray detects lung abnormalities including pleural thickening or scarring effusions or

excessive liquid and lesions fabric growth once the presence of any of these lung abnormalities

 is established any of the following tests may be required to determine if asbestos lung cancer is
present how far it has progressed and what treatments are indicated often several are used in

conjunction to provide a complete picture sputum cytology which analyzes the patient's Flum

may be requested as this test is very straightforward and deceptively simple its importance in

cancer diagnosis may be overlooked sputum cytology can detect cancer cells in their earliest

stages a computed tomography scan CT scan or cat scan is an xray that rotates around the

 patient producing a three-dimensional cross-sectional image unlike the flat x-ray image an accurate assessment of the size of the abnormality can be made and differences in tissue

density can be seen you will have an injection of died before the scan to help show up

 abnormalities positron emission tomography or PET scans help identify tumors and in

suspected lung cancer are most often used to complement information from PET scans the

patient receives an injection of radioactive sugar molecules which causes tissue that uses

glucose to appear brighter on the scan because tumors use more glucose or normal tissue

tumors are readily identifiable with this test although PET scans cannot distinguish between

 malignant and benign tumors ultrasound uses high-frequency sound waves to see the

parameters of a tumor or other abnormality it is most often used in conjunction with

endoscopic or other biopsy procedures while imaging tests like CT scans PET scans and

ultrasound provide invaluable information lung cancer asbestos-related or otherwise cannot be

diagnosed without analysis of the abnormal tissue or tumor this requires a biopsy or physical

removal of tissue for examination physicians usually prefer to make use of the least invasive

methods first resorting to more invasive if a diagnosis cannot be reached needle aspiration

biopsies use syringe needles to suck tissue and or fluid from the patient's lung or plural if a

conclusive diagnose this cannot be made from the material obtained through the use of a fine

 needle or if a larger tissue sample is needed the physician may opt for a core needle biopsy

which yields a cylinder of tissue for examination when the purpose of needle aspiration is to

collect a sample of the fluid that surrounds the lungs where cancer cells can also be found the

 procedure is called thoracentesis if the physician needs larger samples of tissue he may order a vacuum assisted biopsy in which suction is used to pull tissue through a hollow needle vacuum

assisted biopsies are particularly useful in cases where samples are needed from more than one

 location as it can be gathered by this method without having to insert the needle more than

once often these needle type biopsies are performed with the visual guidance of imaging

technology such as ultrasound x-rays CT scan or fluoroscopy live x-ray images transmitted to a screen in a bronchoscopy and endoscopic procedure a thin flexible tube or bronchoscope

 terminating with a light and camera is passed through the mouth down the windpipe and into

 the lungs a bronchoscopy can be used simply to view the upper Airways and lungs but can also

 obtain tissue for biopsy saline solution is introduced through the tube flushing the lungs and

collecting lung cells fluids and other material present sometimes tiny instruments like brushes

 or forceps are pushed through the tube to retrieve tissue samples if imaging tests or a previous

 bronchoscopy shows larger abnormalities or indicates a possible tumor the bronchoscope

views may be rigid and larger allowing larger tissue samples to be gathered similar endoscopic

 biopsies may be performed like a thoracoscopy sometimes called vats or video-assisted

thoracoscopy entering the chest or lungs through small incisions in the chest or a

mediastinoscopy which examines the center of the chest or mediastinum in nearby lymph

nodes as a last step in final diagnosis when needle or endoscopic biopsies show the presence of

 cancer cells the physician will order a surgical biopsy depending on the size of the suspicious

tissue an incisional biopsy involves removing a piece of the suspicious tissue the surgeon will

 perform an excisional biopsy when the lump is small enough to be removed completely at

one time in both cases the tissue is examined to determine if it is benign or cancerous in some

cases a thoracotomy will be ordered considered major surgery a thoracotomy requires a

 surgeon to open the chest and examine the lung directly removing tissue for testing and

analysis without the information provided by proper testing asbestos lung cancer cannot be

diagnosed only a biopsy and analysis of the tissue affected can conclusively determine if the

disease is present how far has progressed and provide informed treatment options thank you

for watching this video was produced by asbestos dotnet a leading resource on all aspects of

asbestos and mesothelioma our priority is to inform victims about the devastating effects of

 asbestos exposure mesothelioma asbestos cancer asbestosis and other asbestos-related diseases

and to advise them with a wealth of information individuals whose lives have been touched by

mesothelioma have numerous questions and concerns their caregivers and family members

also need accurate reliable information.
