Your doctor may need to remove a tissue sample from the tumor (a biopsy) or draw fluid (aspirate) from it to confirm it to confirm the diagnosis. This can be done in several ways.
The simplest way to obtain tissue samples involving making a small incision and placing a flexible tube in the area of the tumor. This is called a thoracoscopy if it is done in the chest area. A laparoscopy is the same procedure, but done in the abdominal cavity. A tube that is that is attached to a video camera is placed so that the doctor can look inside the body. A tissue sample may be taken at the same time. Sometimes, however, a more extensive surgical procedure may be advisable. A thoracotomy can be done to open the chest to take a tissue sample and, if feasible, to remove most or all of the visible tumor. If this procedure is done in the abdominal cavity, it is called a laparotomy.
