What's the process for going from expanders to implants?
Tissue expanders are temporary devices that prepare your chest for permanent implants after a mastectomy. They're gradually filled with saline solution over 6-8 weeks (or longer if you need chemo or radiation first) to stretch the skin and tissue.

What's the process for going from expanders to implants?
Tissue expanders are temporary devices that prepare your chest for permanent implants after a mastectomy. They're gradually filled with saline solution over 6-8 weeks (or longer if you need chemo or radiation first) to stretch the skin and tissue.
Key things to know:
- Expanders typically need to exceed your final implant size by 10-20%, so your permanent implants will actually be slightly smaller than your fully expanded expanders
- Most people find significant relief after the exchange surgery, though you'll be tender for the first few days
- Pain typically requires medication for about 72 hours, then regular acetaminophen works fine
- Many can return to light exercise around 2 weeks and resume normal arm movements by 4 weeks
During the expansion process:
If you're uncomfortable, ask your doctor about smaller fill increments (like 50cc at a time). You can also use this time to decide on your final implant size - it's okay to change your mind about going bigger or smaller.
The exchange surgery is usually straightforward, and most MyBCTeam members report feeling much more comfortable once the permanent implants are in place.
