How does the medi-port affect airline restrictions?

it doesn't unless it is metal and may beep off when going through customs, my doctor gave me a medical card to show when i travel or go through xray machines explaining my wearing a port and also one for my breast implants. I was told that you must talk with your doctor if traveling by airline after a breast removal as the high attitude may help cause lumpademia and you might need to be fitted with a compression sleeve and or glove. I was fitted it help your arms and fingers from any additional swelling.
