Wedge biopsy

Wedge biopsy
For this procedure the doctor makes an incision through the skin and gets a wedge-shaped piece of tumor tissue and sends it to the laboratory for analysis. The patient must be under general anesthesia for this procedure. Sometimes he uses this type of biopsy when other biopsy methods have not been able to confirm a diagnosis.

Cytology and Pathology
The pathology is the study of a disease in which cells and specifically notes the types of disease processes in order to determine the cause. The pathological examinations are carried out on samples of body fluid or tissue to determine the type of cells (cytology) of a specific evil. The process of observing these samples may include the use of microscopes, electron microscopes and several dyes. This refers to a special technique of stained cells to identify specific types of tumors of mesothelioma. Certain dyes and colors are added to the biopsy samples of the patient and depending on how the tissue responds to dyeing, the doctor may then make a better diagnosis of the disease and its consequences. In making the diagnosis, the more information you have about the tumor, the better the doctor can recommend the most appropriate treatment. Knowing the exact type of disease, allows the physician to perform a more specific treatment.

Needle biopsy

Mediastinoscopy
This is a test that examines the mediastinum. This area is located in the center of the chest between the lungs and contains the heart, blood vessels and lymph nodes.

Needle biopsy
For this procedure, the doctor uses a fine needle to take samples and examine the cells under a microscope. This test can be uncomfortable, but only takes a few minutes. Also, your doctor may use X-rays, CT scan or fluoroscopy to guide the needle when inserted into the tumor.

Fluoroscopy is a diagnostic procedure in which X-rays are passed through the body and then projected onto a screen, thus allowing continued to observe an image of internal body structures. You may take small tissue samples and send them to the laboratory for analysis.

Bronchoscopy

Bronchoscopy
A bronchoscopy involves an examination of the lungs and airways. The doctor puts a lighted tube down the patient’s windpipe to the lungs. This procedure is called bronchoscopy and the instrument used is called a bronchoscope.

Thoracentesis
Some patients may develop fluid in the lungs. This is known as pleural effusion. Your doctor may take a sample of this fluid with a needle and injected into the breast examinations to determine if it is cancerous. It could also happen that your doctor performs a drain fluid from the lungs to help relieve pain.

Thoracoscopy

PET scan
It is a procedure in which a small amount of glucose (sugar) radiation is injected directly into the vein and a scanner is used to create computer images that detail the areas within the body where the glucose is used. Because cancer cells tend to use more glucose than normal cells, this procedure and its images can be used to find cancer cells in the body.

Thoracoscopy
The diagnosis of malignant pleural mesothelioma may mean that your doctor performs a physical exam within the chest cavity with an observation instrument called a thoracoscope. For this procedure, an incision through the chest wall and enters the device between two ribs. Generally, this procedure is performed in the hospital.

computerized axial tomography

Diagnosis is the process of determining the type of disease that occurs. An accurate diagnosis is important because it helps determine the type of treatment to follow.

Your doctors may use a set of procedures to help with the diagnosis of mesothelioma. The most common procedures are listed below. Whether you use one of these tests, or a combination of several in the case of a particular patient will depend on factors that are unique to each patient. It is possible to first perform some tests to determine whether a biopsy is necessary. A biopsy is usually necessary to confirm the diagnosis.

CT CT
This type of X-ray provides a very detailed picture of the size and location of cancer. The images obtained are compiled by a computer to create a more complete picture of evil. The procedure is also known as Computerized Axial Tomography, hence its acronym (CAT).

The Stages of Malignant Mesothelioma

Monday, February 22nd, 2010

Stages of Malignant Mesothelioma

Malignant mesothelioma through 4 stages, each more advanced than the other. Your doctor will determine at what stage the cancer is, in a process called definition of the stage, because each stage requires changes in treatment.

Stage I: Cancer is found in the tissues lining the lungs, heart or abdomen.

Stage II: Mesothelioma has reached this stage when the investment has gone to the lymph nodes.

Stage III: Cancer has spread to the chest cavity, the center of the chest, heart, diaphragm or stomach.

Stage IV: The most advanced stage is when the mesothelioma has spread to organs that are not part of the lungs, the heart or abdominal system, such as the liver, pancreas or colon.

Age Groups Most Affected

Mesothelioma has a long latent period between exposure to asbestos and the onset of injury or illness. The latent period can be 15 to 50 years or more. There are also documented cases whose latent period was less than 15 years. It means that a person recently diagnosed with mesothelioma it is likely that for decades has been exposed.

According to NCI (National Cancer Institute), are reported annually in the U.S. Approximately 3,000 cases of malignant mesothelioma. The incidence of mesothelioma appears to increase. Mesothelioma is 3 times more common in men than in women. In men, the feasibility is 10 times higher at ages 60 to 70 years, compared to men between 30 and 40. In the past 50 years, occupational exposure to asbestos in the U.S. are estimated to have affected approximately 8 million people.

Occupational and Environmental Exposure to Asbestos

Environmental Exposure to Asbestos

The widespread use of asbestos has caused thousands of workers who do not suspect, and their families have been exposed to toxic mineral. The Administration of Occupational Safety and Health Administration of the United States has said there is no other example in which exposure to toxic minerals, has proven so harmful to humans, as has exposure to asbestos. It is estimated that from 1940 to 1970, approximately 27,500,000 individuals were potentially exposed to asbestos. This figure is not surprising when you consider that there are an estimated 1.2 billion square feet of asbestos insulation material contained in 190,000 buildings in the United States, and that the number of exposed workers is estimated at 900,000.

Workers exposed to asbestos in many lines of work and workplaces, ranging from construction to mining, manufacturing and consumer industries. According to one author, the Asbestos Information Association has been estimated that up to 3,000 different uses for asbestos, which has the consequence of asbestos exposure in the areas of mining and processing, manufacturing, primary and secondary products contain asbestos, construction and ship repair and building processes, to name a few.

Harmful exposure to asbestos has occurred not only workers of the works, but even the residents and neighboring communities to mining and manufacturing plants of asbestos products may have been exposed. It is estimated that the release out of work from construction areas reached levels 100 times higher than normal level of asbestos in the environment.

Additionally, household pollution also occurs when the worker brings home clothing contaminated with the toxic mineral, thus exposing unknowingly to members of his family. In fact, some believe that the most important source of contamination and non-occupational exposure to asbestos today is that of contaminated materials in homes, schools and public buildings.

What is Asbestos?

Tuesday, February 16th, 2010

Asbestos
Asbestos is a mineral that occurs naturally in the environment and is typically divided into two mineralogical groups, but not all varieties have commercial use.

The family of amphibolites include crocidolite (also known as “blue asbestos”), the amosite (known as “brown asbestos), tremolite, anthophyllite and actinolite. Within the different types of amphibole fibers, only crocidolite and amosite are used commercially. However, the asbestos “noncommercial” (as tremolite, anthophyllite and actinolite) are also present as contaminants in commercial products include chrysotile asbestos, vermiculite and talc.

The other group of asbestos is the serpentine group that includes only the variety chrysotile asbestos. Despite its dangerous properties, chrysotile was immensely popular in the industry and represents 90% of the commercial use of asbestos in the United States.

Alternative Treatments
Alternative Medicine
Alternative medicine and holistic refers to practices that are organic and spiritual in nature. Talk to your doctor before starting treatment alternatives.

Alternative Treatments
Although some alternative therapies can be helpful as an integral part of their therapy or complementary, to date there are insufficient studies to suggest that alternative therapies can replace traditional medical therapies. Always contact your doctor about these treatments before starting any.

Herbs

An herb is a plant or part of a plant that can have therapeutic properties. Herbal supplements can be a single herb or a combination thereof.

You can get herbal treatments in your area by:

  • The search for professional organizations of providers of alternative therapies with herbs at your local library, local directories or via the Information and Resource Directory online at the National Library of Medicine.
  • Consultation with the state regulatory body that brings together suppliers of herbs under license. Also, your local health department may have a listing.

Acupuncture

Acupuncture involves inserting needles into specific body points. Increasingly being used more and more treatments for pain caused by cancer and as a treatment for side effects such as nausea.
