Due to the position of the body and tail of the pancreas within the
anatomy, tumors in this area may develop for some time before causing
symptoms, such as pain or jaundice. Unfortunately, once these symptoms
appear the cancer is usually at an advanced stage, often with evidence
metastases. For this reason most patients with tumors of the body or
tail are not operable.
If the tumor is operable, a distal pancreatectomy and splenectomy is
performed. This is the removal of the left portion of the pancreas and
the spleen.
