Hi, I had a breast biopsy 6 weeks ago, they put in surgical clip to mark the spot. I recently had a mastectomy and the clip was no where to be found. My surgeon said he is not sure where it is, could of fallen when transferring breast tissue. I am worried as I have/had DCIS, and if there are DCIS cells on clip and it wandered, what should I do? Get a chest x ray?
