Ewing sarcoma old portacath

I am having trouble geting my doctor to find my portacath. I was wonder if the reason is a dear hit me in the chest and imbeded it in my muscle. Now only a pillow is on top of the muscle. Or maybe my doctor is incompetent. Funny is if it is a medical mistake is that my blood sample will now cause strokes in ther patients if this is damaged bad enough to clog and bleed regularly then clot again.
