Hi
When my Dad was told he had a mass on his pancreas I started to research what it may be, most sites pointed to pancreatic cancer and unfortunatly this was what it was.
Ask for the CA19-9 results of any blood test (if they say they hav'nt got it as them to test it). This is what they use as a tumour marker for pancreatic cancer.
Also ask them about a laparoscopy (description below).
A laparoscope is similar to an endoscope. It is a long tube with a camera at one end and an eye piece at the other. For this investigation, you are likely to have a short general anaesthetic. The test is done by making several small cuts (incisions) in your abdomen. The doctor puts the laparoscope through these incisions and examines you from the inside. Sometimes the doctor uses an ultrasound probe with the laparoscope. This is called laparoscopic ultrasound. The ultrasound helps the doctor to identify any suspicious looking areas and take a sample of cells to examine.
We are from the UK so the above may be called something different in the US, but any decent surgeon will know what its called. Go armed with all the information you can as Doctors find it harder to put people off when they appear to know what they are talking about.
Fingers crossed that it is benign, but 6 months is far to long to wait to confirm this.
