Allergan is a manufacturer name associated with various products used in aesthetic medicine. For breast implants, the exact model is crucial; statements about one product cannot be applied to the entire range.
Allergan's macrotextured BIOCELL breast implants and certain tissue expanders were recalled in 2019 because of their association with BIA-ALCL. This does not amount to a blanket recommendation to remove every Allergan implant. Implant type, symptoms and medical findings need to be considered together.
People with an implant can find the model details on their implant card or in their operation records. New swelling, lumps or persistent pain should be examined. Current safety notices apply to the products specifically named in them.
