Could I have cancer????

I am concerned about some things that are going on with me and I am hoping that someone can help me.  I should probably mention that I do have health anxiety so I am not sure if I am over reacting or if I should really be concerned.  I have lost alot of weight over the last year (20 lbs).  I went from a size 12 to a 6.  I also have extremely itchy skin (from head to toe) and middle and lower back pain.

I went to the dr last night and she is running a ton of tests to check my thyroid, cholesterol, hormones etc.  She also ordered an ultrasound of my gallbladder.  However I am really concerned about pancreatic cancer.  Someone told me that some of the symptoms I am having can be caused by pancreatic cancer and now I am freaked out.

I wasn't concerned about it until I starting getting the itchy skin.  I don't have any kind of jaundice or anything or any changes in my stool or urine.

This past year has really been a tough year with my anxiety as well.   Which my dr seems to think contributed to my weight loss.  I have changed the way I eat and my appetite is not like it use to be....

I mentioned pancreatic cancer to my dr and she didn't seem too concerned about it.  Am I just over reacting or is this something I should really be concerned about?  

I would appreciate any insight.

Welcome to the gastroenterology community!  I truly doubt you have any type of cancer.  There are many many much more common reasons why you have lost weight other than cancer.  I think you should try to forget about cancer, and wait for your tests to come back and see if those show anything.
