Is It Dangerous to Leave the Tissue Expander In?

If you have had a tissue exapnder in, you sholdnot leave it in as the final reconstruction.  It is better to place an implant or have it removed.

If you are happy with the shape and feel of your reconstructed breast with the tissue expander implant, then there is no urgency to have it removed.  However, a softer saline or silicone gel implant will likely be more comfortable.  Also remember that if your oncologist recommends MRI, you may need to have your expander removed because of the integrated metal backed port.   

It is just uncomfortable to have an expander which is more rigid than an implant. The expander also has a metal port in it which will prevent you from having MRI's and will show on airport screening machines etc...So it is more a convenient to replace it with a softer gel implant. All the best!

An expander is so firm I am surprised you would want to leave it in! I can't see any reason that it would be any  more dangerous to leave in than any other implant. I just had a patient that went 6 years with an expander in place and just had it swapped to an implant.

The implant by and of itself is not dangerous to leave in. However, it is a foreign body and can be prone to infection especially if you have an infection elsewhere such as a urinary tract infection or upper respiratory infection.

Hello,
This is debatable based upon how much scarring you have around that expander. There is no absolute answer either regarding how long it can be left in place.
Expanders tend to be firmer and less comfortable than permanent implants. I would get it out, but I am conservative. If the soft tissue over the expander is healthy, I guess you could opt to leave it in and just see what happened. I don't leave them in long term on a routine basis.
