mesothelioma and pet scan
Mesothelioma is a very rare form of asbestos-related cancer that is more effective to treat when detected early. Unfortunately, the nature of the disease and the fact that remains dormant for decades, usually results in late detection after the cancer has spread to other parts of the body, which is extremely difficult to treat. One of the methods used in the detection and diagnosis of mesothelioma is a surgical biopsy.
Three different types biopsies available for those who have developed mesothelioma. A biopsy is the surgeon removes the tissue in question for laboratory examination. Three types of biopsies are:
1-incisional biopsy or core biopsy
In this type of biopsy only a small portion of tissue is removed. This type of biopsy is used most often when the tumor is located in an area that is easily accessible, for example in breast cancer, however in most cases of mesothelioma, especially in the form pleural and peritoneal tumor disease is not easily accessible. So this type of biopsy is very limited use in diagnosing mesothelioma.
2-The excisional biopsy
Excisional biopsy in all the tumor mass is removed by the surgeon compared with incisional biopsy that removes only a small part of the tumor mass. An excisional biopsy of course, comes with higher risk. The surgery is more extensive and time consuming it is also more complicated and the surgeon until the final disposal of a significant part of the lining surrounding sensitive organs. However, it is always better to operate once very widely that that the patient undergo surgery twice after the same laboratory tests of tissue samples confirmed the cancer.
3-needle aspiration biopsy needle
The third type of diagnostic biopsy is called needle aspiration biopsy. In many cases, this is the preferred technique by surgeons, because is a safe and fast. Although most often used for tumors that are near the surface of the skin, the needle aspiration biopsy (also called needle aspiration or fine needle biopsy) can also be used to diagnose mesothelioma. In essence, this technique uses a long needle and hollow to extract a sample of body cells to be tested and properly diagnosed. When this method is used to collect samples from the cancer mesothelioma surgeon makes use of certain equipment that will help guide the needle carefully where the tumor. After the cells were removed from the body, a pathologist, which is a doctor who specializes in diagnosing diseases through cell structures examines the cells under a microscope for diagnosis. The pathologist employs a number of different techniques for the diagnosis of cells after the biopsy, but in most cases, the pathologist remove a layer very thin tissue sample, placed on a microscope slide, add dye to make the cells more visible, and seals of the slide so it can be examined under a microscope.
A pathologist is trained to analyze the growth of abnormal cells that might indicate mesothelioma and as other diseases. Other techniques used by the pathologist involves the use of specialized biochemical staining procedures to identify specific tumor markers in cancer cells.
The biopsy also allows the pathologist to examine the possible spread of cancer to other body parts. When you delete tumors in the body, the pathologist carefully examines the margins to see if cancer is present. Margins negative "means that the cancer probably has not spread, the emergence of "positive margin" means there is a good chance that the cancer has spread beyond that the mass of the tumor, the surgeon removes. Mesothelioma is spreading fast, so if the biopsy report indicates the presence of metastases as possible, testing Additional CTscans image as X-rays, MRIscans, PET is used to locate the extent of spread.
