Genetics for her too, I'm thinking ...
If you mean my friend with the 2 hip replacements, you are wrong actually. It should be genetic, but noone in her family has it. She grew up in the same neighborhood as my husband who has Retinitis Pigmatosia and kidneys that stopped growing at 8 months of age. Both of those things should be genetic but nobody in his family has it either. His best friend who lived next door was born with a heart condition-same deal with him. The mother of the his (the best friend's) kids lived there for 13 years. Had aggressive cervical cancer twice and had to have a full hysterectomy at the age of 28. My mother in law had to have a full hysterectomy when she lived there in the 80s after a "bad miscarrage". I assume they found something like tumors, but I'm not gonna ask. My sister in law had some fertility problems. In fact, that friend with the hip replacements had a stillbirth at 24 weeks about 7 years ago.
And its not just the girls. Another friend of my husband's had a cancerous testical removed at 19. His younger has MD and is confined to a wheelchair. One of the "neighborhood moms" (mom mother-in-law was the other) died of brain cancer when I was pregnant with J&F. I know of a couple more people my age and a bit older who are on disability for weird shit that should be genetic but isn't that all grew up in the same area. The area is just southeast of the Des Moines airport and a couple miles west of the old Fort Des Moines. A creek runs behind the houses and it floods a lot in the spring. The creek is gross and slimy, but you know how kids want to play in gross slimy shit.
My guess is that military waste was buried in the area a long time ago. The people I have mentioned it to say it sounds plausible, but try tracking it down..
