my friend's mom died of esophageal cancer. she died 2 months after she was diagnosed. she wasnt a smoker/drinker. my friend said that there are more women in her family that had it. and her doctor told her it was highly hereditary

i looked it up on the computer and found out that black ppl are more likely to get it than white people (her family is white) and men get it more than women (women in her family had it) and it said that it wasnt known if it was hereditary. she has an aunt on her DADs side that was just diagnosed with it yesterday.

she is worried she will have it. any information i could share with her?
