My sister had breast cancer at 30. She went for genetic testing and they said she doesn't carry the gene. I forget what they call it. My Dr said if she tested positive then they would have recommended I go for genetic counseling.
If you are born in a big family and each one gets one illness, then it feels like you should get tested for every illness in the book because of genetics.
My dad had 20 brothers and sisters. My mom has 11. I have 150 cousins But I'm not going to worry that I may get what everyone else has. I'm going to try to leave some room to live!
