Hi Hillary,
First, I’m sorry to hear that both your parents have passed. That’s tough. Gentle hugs. ❤️
It has been explained to me that (and I’m not sure there is a definitive answer) MDS is familial meaning it runs in families but it’s not inherited. Maybe others here will offer better info.
In my case, my grandmother died of multiple myeloma, my dad from bone cancer, I have a cousin who survived AML and then there is me with MDS.
BUT I also read that with the all the breakthroughs in genetics some are leaning towards their being a genetic link. (See article below in link)
I would talk with your primary care physician about your concerns and maybe they can steer you in the right direction.
