Your question is an interesting one because it is really a reflection on human nature.  Let me explain.  Your breast implants appear to be serving you well.  You have a good size and shape for your body.  The implants are in a good position and they have obviously served you well and should continue to serve you well for years to come.  Yet, you are clearly thinking about doing something with your breast implants because you have heard about breast implants and, in particular, Allergan’s textured breast implants, causing cancer, anaplastic large cell lymphoma (ALCL).
With the implants you have, your risk of developing ALCL is one in thirty thousand (1:30,000) over the rest of your lifetime.  Now, if you develop ALCL that is obviously a problem but the chances of that are very, very small.  Put in perspective, the chance you die of heart disease over the rest of your lifetime is 1:3; a car accident 1:45 and a plane crash 1:4000.
When I say your question is interesting, I mean that we often do not put everything into perspective when we consider certain actions.  While I am sure you can find someone who will be willing to remove your breast implants for you, there is certainly no need and the vast majority of plastic surgeons would advise against it for the reasons I have outlined.
What you should do is continue to monitor your breasts routinely for breast cancer, the kind we are all familiar with, and at the same time be aware that if you do develop a problem related to ALCL and your implants that the presenting symptom is large swelling of the breast that occurs over a few weeks.  If that occurs, you should then see a board certified plastic surgeon near you who can properly and accurately diagnose the problem and then guide you through the appropriate treatment.
With respect to the age of your implants, there is a myth on the internet that you should change your implants ever 10 years.  Your breast implants are warranted for life so again, there is no reason to change something that is not broken.
