Lisa - Two members of the same family getting oral cancer is certainly unusual, but not impossible. By the laws of averages, there is no reason that every other person on the block could not come down with oral cancer - its just very, very unlikely. Genetics are believed to play a role in certain cancers, though to my knowledge there is no reliable genetic link for oral cancers. Environmentally, smoking and alcohol are belived to be linked to oral cancers.

There is a local electrician here who has been hit by lightning on seven different occasions! What are the odds against that happening??!!

My best to your aunt Rosemary. Be strong, Tom
