You do realize that chance of developing cancer is hereditary , right ? There are mutations BRCA 1 and BRCA 2 being the most wellknown that are associated with a huge cancer risk . People with these mutations often get preventative mastectomies and oophorectomies . It sounded like men and women on one side of her family died of the cancer though , so she is probably carrying a different mutation that ' s where the 50 % comes from . Cancer is entirely a disease of genetics , though it is not always hereditary . In her case , it probably is . <| sep |> Well , i would say i name my Pokemon , but i did name my Pokemon some slightly insulting name , my Male Primarina is named Talapi which is Trap in Sort of Hawaiian , My Gengar is named after someone in my class who sort of looks like a Gengar , and my Dugtrio is named Sportaflop , because apparently sport is racism and Sportacus is the worst Fat Shamer oh goodness , Tumblr , don ' t get ideas
