Swelling and bruising may occur after surgery, and how long they take to subside varies from person to person. A scar remains at the incision site, and in rare cases bleeding, infection, inflammation, or left–right asymmetry may occur, which may require additional treatment. In revision surgery, what can be corrected depends on the capsule formed by the previous surgery and the condition of the remaining breast tissue and skin, and if an implant is inserted again, problems such as capsular contracture, rupture or displacement of the implant, or rippling, in which folds of the implant can be felt or seen through the skin, may occur again, so please tell us at your consultation when and how your previous surgery was done and what type of implant was used. If the implant is only removed, the breasts may lose volume and appear to sag. After surgery, hematoma or seroma (a collection of blood or fluid around the implant) may occur, or the sensation of the nipples and breast skin may change. Please tell us at your pre-surgery consultation about any medications you take, including blood thinners such as anticoagulants, as well as any medical conditions and whether you smoke. During recovery, please avoid alcohol and smoking and attend follow-up visits as scheduled. Please make your decision after you have been fully informed of the risks and of alternative options. Results and recovery vary from person to person.
