I have just had a marginal mandibulecomy on right bottom side to remove mucosal melanoma found on my gums there. The MD says this is very rare and that I should not pay attention to information on oral cancer or melanoma. He says it is so rare there are very few resources or studies available. I have asked him to send me any information he might have. I am wondering if anyone else has this diagnosis and any ideas on where to find reliable information. Thanks.
