We're talking self-mutilation here, and serious one (removing one's ovaries) and now suddenly it seems it's not a big deal.
Nobody has said or implied that it's not a big deal. Medical decisions like this are a huge deal.
If she wants to do it to remove the risk, that's her choice. But hailing it as something that everyone should do is another thing.
No one has said it's something "everyone should do." What people have said is that it's an option everyone should have, and that it's a decision people ought to be able to make one way or the other without someone else disrespecting their choice.
Just out of curiosity, how many of you would remove your ovaries or testicles if you were told there's a 87% chance of developing cancer?
If I had an 87% of developing a cancer that is extremely difficult to detect before it reaches an advanced stage, and that cancer had killed both my father and my grandfather at a young age? Yes, I would have my testicles removed.
And no, being able to decide what to do in relatively little time does not make it an "easy" decision. The necessity of a decision can be clear and reached in a short period of time, yet still be very emotionally loaded and difficult. "Hard choice" does not always equal taking a long time to make a decision or being unable to reach a decision by weighing the costs and benefits; even when the benefits outweigh the costs, the costs can be dear.
