Coolsculpting and breastfeeding: Is it possible to frozen cells can make there way into the milk?

When CoolSculpting is performed, it will only affect the fat cells in the treated area.  There are not "bad" cells that circulate throughout the body or enter the breast milk.  

While it highly unlikely the treatment will affect the breast milk, it would be best for breast feeding mothers to not do coolsculpting until they finish breast feeding.

Coolsculpting is a unique way of freezing the fat cells in a given area.  The fat cells are destroyed locally in that area.  Coolsculpting is not a knonw contraindication for breast feeding but you should also check with your pediatrician as well.

It is very unlikely that the dying fat cells would be able to travel into the breast milk. CoolSculpting only affects the fat cells in the treated areas. 

Not really.coolsculpting works by freezing fat cells to induce programmed cell death. Your body has a mechanism to remove dead cells throughout the body. It is unlikely that random dying fat cells will travel into the breast milk. Even if that were possible, dying fat cells are not dangerous, per se.
