I've had implants for 26 years. There are pros and cons to them. First and foremost, they are not a lifetime device. Please know that some implants last years, and some rupture within 5 years. The implant begins to deteriorate the moment it is implanted. Some believe the deterioration rate depends on how your body responds to the foreign object. They really don't know why some deteriorate faster than others.
I've replaced my implants 3 times in 26 years. I've had silicone, saline, and now cohesive silicone. If you have little to no breast tissue, silicone is the best option & most natural looking. I have very little breast tissue and I had ripples with saline implants.
I highly recommend that you join a breast implant forum so you can read experiences from a larger pool of women. Don't ignore the sad stories, it's important to know all the risks! Most women are happy, but there are women who have suffered complications.
I've met a few women who for whatever reason, their body did not like the foreign object, developed problems (hematomas, infections, capsular contraction), and had no choice but to remove. It's heart breaking, but it happens.
When you save for the initial implant, make sure you have extra money for complications. Revisions cost more.
One of my friends had one implant that did not settle right (asymmetry) and needed revision 6 months after implant. The cost of revision is the responsibility of the patient, not surgeon.
