radiation

I have been having abdominal pain since January along with weight loss and no one can figure out what is quite wrong.  In the past 6 months here are all the test that I have had done.
Jan 2007   Chest X-ray
Mar 2007   Upper GI Series and CT scan with contrast of abdomen and pelvis
May 2007  CT scan of head in ER
June 2007  Radiation given for Thyroid Cancer followed with I-131 body scan
July 2007  2nd Chest X-ray with 2nd CT scan of abdomen and pelvis
July 2007  Upper Endoscopy EGD

I am now starting to worry because of all the tests I have been going through and the exposure to radiation.  How much radiaiton is too much?  I am scared that with all the tests that they have been performing my chances of getting cancer from exposure are greater?

I do not follow included in the lists of tests is Radiation given for thyroid cancer followed by I-131 body scan.  Do you have Thyroid Cancer or surgery to remove it.

Please give the results of the tests and more information about diagnosis of thyroid cancer.

We need more information in order to answer the question.
