Radiation and Breast Reconstruction

Effect on Tissues: Radiation therapy can affect the quality of tissues, making them less pliable and more prone to scarring. This can impact the success and outcomes of breast reconstruction.

Timing of Radiation: The timing of radiation in relation to breast reconstruction is an important consideration. In some cases, radiation is administered before reconstruction, while in others, it may follow the reconstruction.

Tissue expander/Implant Breast Reconstruction: If radiation occurs after breast reconstruction with implant is completed, significant changes including tightening/constriction and higher position of the implant on the chest may occur, causing significant asymmetry compared to the non-radiated breast. This may be addressed to some extent through surgery and fat grafting. Any surgery should be delayed for about a year after the last dose of radiation to reduce risk of complications. If radiation is started after placement of a tissue expander, replacement of the tissue expander for a permanent implant is delayed for a year. There are pros and cons regarding radiation after tissue expander placement vs after replacing tissue expander for permanent implants. The risk of complication is higher after the former, but the aesthetic results tend to be better.

Autologous Breast Reconstruction: Autologous reconstruction, where tissue is taken from another part of the body (usually the abdomen or back) to reconstruct the breast, is another option after radiation treatment. Due to the diminished quality of skin and subcutaneous tissue, sometimes using autologous tissues is the only way to reconstruct a breast. The impact of radiation on these tissues should be taken into account when planning this type of reconstruction.

Complications: Radiation can increase the risk of complications in breast reconstruction, such as delayed wound healing, increased scarring, and changes in the appearance of the reconstructed breast. It may also affect the long-term cosmetic outcomes.

Consultation and Planning: Communication between the breast cancer surgeon, radiation oncologist, and plastic surgeon is essential for effective planning. A comprehensive discussion about the potential impact of radiation on reconstruction options, the timing of treatments, and the patient’s circumstances is crucial.

Patient Considerations: Patients should be well-informed about the potential challenges and benefits of combining radiation therapy with breast reconstruction. Factors such as the type of cancer, the extent of surgery, and individual health considerations play a role in decision-making.
