A biopsy of the tumor must be done to definitively determine the presence of a sarcoma. This test removes a sample of tissue for analysis under a microscope by a pathologist. There are several ways to accomplish this, depending on the size and location of the tumor.
A decision to perform a biopsy is important and should be made in consultation with a physician who is knowledgeable and skilled in the diagnosis and care of sarcomas.
Improper biopsies can result in the tumor spreading, or and can make it difficult to remove the tumor later. So, the experience of the surgeon is very important in these procedures. Levine Cancer Institute's surgeons have a high level of expertise working with sarcomas, and not only provide the most accurate diagnosis, but the very best outcomes.
Chest X-rays, CT scans, MRIs and PET scans can also aid in determining anatomic features of a tumor in planning biopsies or determining if cancer has spread to lymph nodes or other sites.
