On a recent thread from today it was mentioned that we are told how infrequent it is for kids to get surgeries in pursuit of gender identity goals. I had posted this in the "it never happens" thread, but it probably deserves its own post to avoid derailing the other thread.
This report is from last year, but is collates data on "gender affirming surgery" in the US.

Tread carefully, their definition of "child" goes up to 18, so there is probably some statistical fudgery, but here are some choice excerpts:
"Patients with diagnosis codes for gender identity disorder, transsexualism, or a personal history of sex reassignment were identified, and the performance of GAS, including breast and chest procedures, genital reconstructive procedures, and other facial and cosmetic surgical procedures, were identified...
Overall, 25 099 patients (52.3%) were aged 19 to 30 years, 10 476 (21.8%) were aged 31 to 40, and 3678 (7.7%) were aged12 to 18 years."
"Performance of GAS has increased substantially in the US. Breast and chest surgery was the most common group of procedures performed. The number of genital surgical procedures performed increased with increasing age."
Mastectomies therefore appear to represent a huge number of cases.
