Breast implant calcification. Coloured mammogram (breast X-ray) of calcification around the borders of a breast implant (pink) in a woman's breast (red) as seen from the side. Breast implants of silicone gel are implanted for cosmetic purposes, or to reconstruct a breast following surgery. One of the possible side-effects is scarring and the deposition of calcium in the tissue surrounding the implant. This can make removal difficult.
