Thanks.... I am 36 from a pretty high risk gene pool.... I have looked into it ~just~ a little. ;~D
You want to talk about high risk? Check this out. The paternal line: My dad: malignant melanoma and non-Hodgkin's lymphoma (he's doing OK-age 70). My aunt: breast cancer (she's doing fine). My uncle: non-Hodgkin's lymphoma (died, age 50-something). My grandfather: metastasized colon cancer (died-age 70). One of his brothers: Leukemia (died-age 60-something). One of his brothers' grandson's: bone cancer (died-age 30-something). My grandmother: breast cancer (survived--she now in a nursing home and her mind is gone-age 80). My grandmother's brother: "eat up" with some sort of cancer (died-age-late 70's). His son: liver cancer (died-age 50-something). My grandmother's sister: Lung cancer (died, age 70-something-oddly enough, she's the only one of this group who never smoked and wouldn't let her husband smoke in the house). Another of my grandmother's sisters: brain tumor (still living-in her late 80's). And that's just the ones I know about off the top of my head. On my mom's side it's all strokes and high blood pressure and type II diabetes, even though they live to a pretty good age (70's and upper 80's).
When it comes to genes I'm screwed up one side and down the other, so I may as well just live my life (and get yearly mammograms and physicals and wear sunscreen).
I don't fault this 22 year old for doing this, though. It's extreme, but she's the one who has to live without her breasts, hopefully until she's 90.
