Here, the recommendation is for women age 50-74 to have a mammogram every two years. (Every year for age 40-49.) The recommendation for trans women in those age ranges is to begin 5 years after starting HRT.
Because my breasts have "heterogeneous density", I have to have one every year. I have had two so far. The technicians have been very respectful.
On my first one, the tech was doing a short interview prior to the mammogram. One of the questions she asked was, "Do you still have your uterus?" I smiled and answered, "I never had one of those." She went, "uh-huh" and started to note my response, and then did a priceless double-take: "Wait. What??" I savoured her reaction for a second or two before explaining. We both had a chuckle about it. Then she asked if I had implants. Nope, 100% natural. If I'd gotten implants, I wouldn't have gone with an A-cup!
