Things to consider if money is a factor...they are not a lifetime device.
You will need to pay to remove or replace them sometime in your life.
I've had mine replaced twice.
Revision surgeries cost more than the initial surgery, because they require more skill.
If everything goes right, the average life of the implants is 10-15 years. There are risks of a rupture, capsular contraction, chronic nerve pain, infection, or you implants may not settle correctly. A surgeon can't know exactly how your body will heal, and many times they have to go back to adjust the implant.
I met a girl who had no choice but to remove her implants because she developed one infection after the other. Her surgeon told her that she needed them removed because her body did not like them. This is rare, but you need to know that there are not so happy endings. My surgeon told me to have money in reserve for complications, because there are no guarantees.
No one could talk me out of my choice to implant, but if what I tell you puts doubt into your mind, then don't do it. Wait until you are absolutely certain. It is difficult to undo once you've done it.
My suggestion is to research research research, and read implant/explant forums for several months before you make this decision.. Read the posts from women who are happy and women who have suffered complications. On a side note..be careful of the docs who advertise on the forums. They pay to get their name out there. Some of the best surgeons never advertise, but they are booked several months in advance by word of mouth. I'm not saying all surgeons who advertise are not qualified, but do your research and consult with several surgeons.Be wary of a surgeon who tries to sell you a procedure.
