Can I wear piercings (ear & face) at my breast clinic appt?

I'm overthinking everything for sure since waiting to attend my breast clinic appointment.

 

I'm due to have mammogram, ultrasound, and biopsy but am not sure whether I'll be allowed to keep all my piercings in (face and ears) or not.

 

Can anyone confirm? I have bought alternative plastic and rubber jewellery just in case but I don't really want to have to change them all.

 

Yes or no to metal piercings?

 

Apologies, because it's all so out of my control, I'm controlling all the little things instead.
