First, dont panic. I did and made some bad decisions.
DCA did not work for my lymphoma. DCA has no proven record of success.
Second, if you have insurance go to Dana Farber Cancer Clinic, Best in the U.S.
Third, if asbestos is the cause you may have a claim against the company who Put the asbestos into wherever you came into contact with it. I have seen Attorneys advertise on TV about this. I advise hiring any lawyer on contingency basis only. He does not get paid unless he gets you a settlement. Do not pay any lawyer uofront no matter what he promises.
Hope it is false alarm, but worst case scenario put youself into Fana Farber's hands. If you want to try DCA to satisfy your curiosity it probably wont do any harm, but dont forgo real medical treatment.
