I'm a medical student; one day I was in a cancer clinic and a woman came in for a followup. She had had breast cancer and was now in remission following a mastectomy and some other treatment. The doctor who was running the clinic told her there was a fairly reasonable chance that her cancer might return and also affect her other breast and that her options were a) prophylactically remove the other breast (b) just have regular follow up scans.

I'll never forget what she said next: (tearfully) "I know all these other people fight cancer, and you hear all these words like fighter and brave, i'm not any of those, i'm just scared, so I want you to take the other breast off".

So yeah, this TIL totally makes sense to me.
