You should keep in mind, when choosing to augment your breasts, that additional interventions may be necessary over time, as well as future consultations with your surgeon.
Your breast implants will need to be replaced over the course of your life. Implants are not lifelong devices, they are subject to wear as other devices that are implanted, e.g. dental fillings, cardiac valves, artificial joints.
Many of the changes made to your breasts will be permanent. If you choose to remove implants later, additional procedures will be required to correct folds, lashes, and other changes. The breasts will be loose with age, with the passage of time and subsequent pregnancies.
