Suture calcification in breast

Last revised by Yvette Mellam on 3 Mar 2023

Suture calcification in breast can be seen after a lumpectomy and/or radiation therapy. It is theorized that tissue damage from radiation therapy delays the resorption of the suture. The residual suture material is thought to act as a nidus for calcification.
