The term biopsy can be taken to mean a view of life and can be taken to mean from the Greek “bio” meaning life, and “-psy” meaning vision. A biopsy is literally a look at living tissue, and is a test used to detect cancer. Any tissue or organ in the body has the potential of being be biopsied, and there are several techniques used. Some of these engage surgery, whereas others will not even engage an anesthetic. In each method, a sample of tissue is extracted from the body and studied for cancer markers, cancer cells, or unusual cell division. Each cancer has its own methods of diagnosis, but the different types of biopsies can be classed. Naturally, you should go to a reputed medical clinic to get this done. You can look up an online health directory to find information.
1) Excisional biopsy. This is a surgical removal of the possible tumor growth. In this case, either an organ or lump is excised, or cut out of the body. Excisional biopsies are used for a variety of cancer diagnoses and for different reasons in each. In osteosarcoma they are used because of the growth rate of possible tumors. Surgery will always be the first preference of biopsy in bone cancers. In lymphoma, tumors can only be examined as whole pieces to obtain an accurate diagnosis. Breast cancer another cancer-type where ordinarily surgeons prefer surgery. This will make certain any cancer diagnosis with the most accuracy.
2) Incisional Biopsy. Here only a section of the lump is removed through surgery. This type is generally used for possible soft tissue cancers.
3) Endoscopic Biopsy. This is the most preferred form of biopsy and is performed through a fibreoptic endoscope that is placed inside the organ of disruption. The doctor looking through the endoscope can view directly any abnormal sections and cut or pinch pieces of tissue with forceps. A thoroscopy for endoscopic biopsy under general anesthesia will be used for mesothelioma, a cancer of internal organ lining. The reason for this is there is simply no other methods to obtain a tissue sample. Meshothelioma is also very tough to detect through other means, and so excisional biopsy is the best course for an accurate diagnosis.
4) Fine needle aspiration is the most preferred form of biopsy today. Here a needle will be placed inside the lump and a large number of cell tissue will be drawn through a syringe. These cells will then be stained and studied by a pathologist. In this case, a diagnosis is reached at once. This kind of biopsy can even be carried out on difficult to reach organs such as the pancreas or lungs with ultrasound guided techniques. This is the preferred choice as avoiding surgery is almost always first on the wish list of the cancer specialist.
There are other forms of biopsies, but these categories are the most preferred and cover most of the major cancerous diseases. If a cancer is possible, a patient may have to go through more than one of these tests through the course of their treatment, depending on how aggressive the cancer specialist feels it is.
Specialist medical clinics are most prepared to deal with this. If you want to learn more, read web pages on the issue. These are found easily in a health directory.
