The risks of breast reconstruction can include fluid build-up in the breast or at the donor site and slow wound healing. After a skin flap reconstruction, there may be tissue death (necrosis).

With any surgery, there is a (low) risk of post-operative infection, bleeding, and swelling.

Fatigue is often associated with this surgery.

With implants, there is a risk of rupture or leakage. This may result in more surgery to either remove or replace implants.

There can be changes in breast sensation and asymmetry.
