Can a pituitary tumor just disappear

[Chrisdoc9270]

In 2007 I was diagnosed with having a microadenoma.   I didn't take any treatment.  Basically, did blood tests to watch my prolactin levels.  Two weeks ago, my prolactin levels had increased and I was scheduled for an MRI.   Yesterday the results came in and no microadenoma present on the MRI.   I don't understand.  Can a pitutiary tumor just disappear?  Your help is greatly appreciated.  Thanks!

I do appreciate your quick reply.  I am just returning home from the endocrinologist's office.  Had too many unanswered questions.   He's a good doctor and saw me right away.  He says all tests came back ok.  Tested the thyroid too.   Turns out I have something called macroprolactinemai.  

I have to do some research on it.   Thanks so much for your information that you provided!

The magazine is "Scientific American". There is also lots of material documenting this on the internet, for example "American Scientist magazine, 34 volume 97. There are over forty documented instances of tumors disappearing after an erysipilas infection. The Coley toxins were essentially heat-sterilized S.pyrogenes and mercescens bacteria.

Yes. Specifically after receiving a killed bacterial vaccine, or experiencing systemic infection. When a person is injected with a killed bacterial vaccine tumor necrosis factor (TNF) is generated, which sometimes causes tumors to disappear. The same things happen when the body fights off systemic infection. This was discovered in the 1920's by Dr. Coley, the founder of Sloan-Kettering, and the phenomena has been discussed in several issues of the Scientific America magazine. During the 1920's it was suggested that cancer patients be exposed to infections to cause regression of the malignancies. The killed bacterial vaccines were marketed during the 1930's (specifically to cause tumor regression) by Lily Corp. as the "Coley Toxins".
