When it comes to certain ailments in family history, the first thing they look at is the age of when the person got sick. Each serious illness has an age cut off, the older they are when they have said illness, the less concerned they are for you. Since your mom had it at only 19, I’m sure they did extra testing just for due diligence. For example I had gi stuff going on and have a lot of colon cancer in my family, but everyone was diagnosed over the age of 60 so it really doesn’t matter to them
