Airport X-ray machines and a prosthesis

I had a horrible experience at the Brisbane domestic airport and I wasn’t even flying.  Our daughter was flying in (had just got engaged) and we were picking her up so very excited.  Went through security to get to the gate and then all turned to shite.  My prothesis was picked up on the body scan so the security lady in her loudest voice yelled “woman here with something in her bra”.  Several staff came over and I explained what it was but they weren’t happy with that so was taken into an office with 4 staff to be felt down.  They then asked me to remove my shirt and had to actually show them my bra.  All happy then I went back out and had to go through the body scanner again and same staff person yelled out again that she still has something there, I started crying, my husband wasn’t allowed to come near me and they finally said I could go.  Have never felt so humiliated and violated in my life. Have flown a few times since with no drama at all but have serious anxiety now before travelling.
