Can mast cell tumors go away on their own?

Mast cell tumors rarely disappear without treatment but some well-differentiated tumors of this type that occur in multiple sites in young dogs and may sometimes regress spontaneously. This condition is sometimes called ‘mastocytosis’. These ‘tumors’ may be not true cancers but a hyperplasia (non-cancerous overgrowth).
