Hi,
i'm so sorry to hear about your dad's problems! I also have a pituitary tumor. I have a microprolactinoma and am currently taking dostinex to lower my prolactin levels. I only started the drug in november, but all of my symptoms have disappeared already. I don't know anything about asbestosis. However, for the pit tumor, there's a whole lot of information over on the msn message boards....Articles to read and people who have been dealing with tumors for a long time, tumors including prolactinomas, acromegaly and cushings disease, even empty sella syndrome.
there are several men with large prolactinomas that chat. They'd be happy to answer any questions they can.....If your dad's is a prolactinoma. If its a different tumor type, you'll have better luck on the msn boards. Good luck!
