By ADC, do you mean adenocarcinoma?
Most posters here have been diagnosed with squamous cell carcinoma, but there have been a few with adenocarcinoma.
Use the Search function at the top of each page to find them -- use adenocarcinoma as your search term and be sure to Search All Open Forums to get the maximum results. Also do a separate search using the search term adenoid cystic carcinoma, which will bring up different posts.
Once you find others with the same diagnosis, you can contact them by e-mail or private message using the icons at the top of each of their posts.
You can get more information about adenocarcinoma from the main part of the Oral Cancer Foundation site -- the Search link at the very BOTTOM of each forum page (in gold) goes to the search function of the main site.
