What are the risks and side effects of breast fat grafting?

Short answer
Risks include fat resorption with loss of volume, lumps from fat necrosis, oil cysts, calcifications, asymmetry, bruising and swelling, infection and, rarely, fat embolism. Calcifications can appear on mammograms and need to be interpreted by a radiologist. Liposuction at the donor site adds its own risks such as contour irregularities.
