I'm not sure if I belong in this group since my oral mucosal melanoma surgery successfully removed the cancer with large and clear margins. But, mucosal melanomas are rare and aggressive with no known risk factors. So, I think of myself as having a rare disease nonetheless because the cancer could return or spread. So, although all of my pre-surgical and post-surgical indicators are good, I face an uncertain prognosis. What I currently deal with is anxiety that derives from that uncertainly and from living from full body scan to full body scan hoping for continued good results. I suspect that folks who have had and are dealing with one or another form of mucosal melanoma know what I mean.
