Google prophylactic oophorectomy. I saw the same stats, six vs two pct, stg like that. The basic problem is, having the operation ahead of time isnt that good for you, BUT if you DO get ovarian cancer, youre gonna wish you had done it. Another but, they cant tell until after you have it and its kinda too late.

it also seemed like your current age was a big consideration. If you were around 35 and done having kids and had the operation, it was more worth the risk because you had more to lose by dying young. But now that we are kinda old - idk. I am trying to stay away from anything that isnt absolutely necessary. And i too would opt for chemical over surgical.
