Is my microwave oven safe to operate? In the middle of the oven, situated opposite the microwave source and below the carousel plate a two inch hole has developed over time. It is found rusted. Presently, when it runs I leave the kitchen after switching it on as a safety  measure. Is it safe to operate it? Can it be repaired? If so, how?

EDIT: The rusted floor (of SAMAR Panasonic) is shown, glass carousel plate removed exposing the hole beneath. Thanks for any suggestions.
No.  Depends upon the construction of the microwave.  I spoke to an electrical/electronics engineer with over 40 years experience and he said. NO NO NO. Replace it straight away. It could be safe, however without it being in front of him he does not know.
