Breast Shrinkage 10 Years After Radiation for Breast Cancer?

Hello!  It is common for the breast to undergo shrinkage from the radiation.  Depending on the deformity and asymmetry - options include an implant, but more likely mobilizing tissue to reconstruct the lumpectomy defect or simply fat grafting.  Fat grafting has become a popular procedure to improve aesthetic outcome following breast reconstruction or for improvement of contour after lumpectomy. Much of the newest research has investigated the properties of fat, in terms of its stem cell properties and associated advantages. It has significantly ameliorated radiation damage by increasing vascularity. Also, it adds additional "fatty tissue" atop the reconstructed breast mound to further contour any concavities or deformities, while also masking implant visibility with rippling and such.At our Breast Reconstruction Center, we have utilizing this technique almost routinely to maximize the aesthetic outcomes after lumpectomy or mastectomy. We have utilized the micro-fat grafting technique, and have been obtaining maximal fat graft survival into the breast. After harvesting of the fat from areas with excess fat, usually the belly, hips, or thighs, the fat is processed and injected back into the breast using the aforementioned techniques. Our patients have been very happy with the results as well as the areas where the liposuction was performed. Contour has been much improved using the micro-fat grafting technique, and the downtime is minimal.  Fat grafting has become a mainstay in breast reconstruction and has added another edge to breast reconstruction for aesthetics with minimal morbidity and complications.

Radiation treatment for breast cancer causes permanent changes to the breast which limits the surgical options. Shrinkage after ten years is uncommon though. Sometimes the natural changes to the unaffected breast make them look more asymmetrical. Regardless, options are to reduce/lift the unaffected breast or do a muscle flap procedure to the radiated side. Implants in a radiated breast are more prone to problems such as capsular contracture.

The effects of radiation are chronic and may go on for many years. This has to do with fibrosis of the tissue, leading to decreased blood supply which may atrophy or shrink over time. Weight changes can also affect the symmetry between the breasts, as the non radiated breast usually changes more with weight gain.
