What is an excision biopsy?
In general, the biopsy is to remove tissue for the purpose of microscopic examination of tissue by a doctor who specializes in pathology. Excursion biopsy is a procedure to remove the weight of the tissue, which is probably malignant or cancerous. It is essential for the diagnosis and treatment of small or non -metastatic cancer, such as melanomas and localized cancer such as breast cancer. This procedure can also be used to detect deeper or metastatic cancer on which surgical or medical procedures can be considered a definitive treatment. This can be done to remove suspicious lumps of the skin, breast, thyroid and other parts of the body. There may be times when the mass is not visible and is located deep in the body. For example, lymph nodes of para-aortal nodes near aorta and heart can be enlarged due to metastatic lung cancer. In this case, biopsies are performed to remove lymph nodes and explore them.
When breast lump is detected and cancer is suspected, it can be a preferred method for lump removal excision biopsy. Breast biopsy led by wire is a special type of surgical biopsy, where the radiologist helps the surgeon in lump removal. The mammographic machine is used to visualize the lump and insert the needle connected to the wire. The surgeon monitors the wire and cuts the breast mass, which is then sent to the pathologist for a definitive diagnosis. A biopsy led by a wire is best used for breast lumps that are visible on mammography but are not tangible or visible.
In excision biopsy, the removed sample is histologically or microscopically examined. The pathologist evaluates the surgical edge of the removed tissue. If the pathologist reports that there are clear or negative margins, it means a woman of the sample edges have been found ancerative cells. When a pathological report states positive margins, it means that cancer cells have been found on the edges and for the treatment of Ja diseaseE need a wider excision.
An important advantage of performing excision or surgical biopsy is to obtain a large sample, reducing the likelihood of diagnostic errors. This procedure requires stitches, leaves a scar and can cause significant bleeding or infection. The decision to make a biopsy of excision instead of other biopsic techniques usually depends on the type of suspicion of malignancy, how much matter is and how accurate the diagnosis will be.
