Hi Julie:

So, this is a scary tough one and probably feels like a double whammy in a land of complete vulnerability. The answer to your question is that oral cancer most often metastasizes to the regional lymph nodes of the head and neck followed by the occurence of tumors in what is known as the aerodigestive tract which includes the esophagous downward. It can also present as second primary tumors in that region and the lung as a common site.In late stage cancers,metatstatic tumor spread can go to the bones. The breast is typically not a common site for oral cancer to spread to so I hope this is reassuring. Best of luck on the outcome and keep us posted.
