I get the sentiment but actually it’s much more common for cis women to be getting mastectomies then for trans people to. Just because in general “gender affirming care” and other treatments are typically given to cis people due to population density. That’s why we know it’s safe for trans people to get these procedures.
that doesn’t really apply to this situation though. although similar, mastectomy for cancer is a different procedure than top surgery. and surgeons who do top surgery rarely overlap with surgeons who do mastectomies for cancer (and this specific clinic only does aesthetic procedures). and if you’re a nurse working with a surgeon, you definitely know the procedures that they perform. so there’s not really a reason you’d confuse a patient having top surgery for a patient having a mastectomy.
