Reply to comment by AskMrScience in Cancer timeline: treatment for stage 3c triple positive breast cancer (all cancers are unique, this is my personal timeline; similar diagnoses will have a similar, but not identical, timeline) [OC] by BluebellsMcGee

My friend Katie died of her chek2 mutation at age 32. It was long and horrible and she told me that if she could go back, she'd get the surgeries. It's not as famous as BRCA but it has a range of health effects. No woman on that side of my family has lived past 50

Debra was also about 30 when diagnosed. She got lucky: if you catch appendix cancer in Stage 1 like they did for her, it's basically "snippy snippy, congrats, you're cured!" She's since had all the other recommended prophylactic surgeries and gotten her kids genetically tested.

I'm a geneticist working on cancer treatments, so this is all Relevant To My Interests. Most hereditary cancer syndromes are caused by a DNA repair or checkpoint gene being mutated (no surprise, CHEK2 = checkpoint gene). I'd think you'd be equally likely to get cancer in any tissue type with that kind of problem. But instead, there are very strong patterns to which organs the cancers tend to start in.

Hooray for being able to ID these mutations and what tends to go wrong. Now we have some clue what to watch out for in each person. And I wish you better luck going forward.
