I'm surprised they didn't have a woman in the room with you, surprised they didn't ask if you'd like one present. I think you are entitled to have one. Be sure and ask for a breastcare nurse to be in any room you're in during any part of your treatment if you think that would assist or make you feel more comfortable. They may not be able to always provide one, but there's no harm in asking. You can have a note put on your file that you'd always like a woman present. Your GP should be able to help you with that.
I hope you're not too sore. I was from mine but an ice pack for a couple of days helped and then it was just bruising. K xox
