1 They do their best work at 55ÂºF, but can carry on right down to 0ÂºF. As they eat away at organic materials, they give off a small amount of heat.  Mesophilic - Second wave of microbial activity. Most of the decomposition in a compost pile is mesophilic.
In general, it is thought that implants last approximately 10 years or should be replaced every eight to 10 years. A ruptured saline implant is clinically obvious as the breast will deflate and there will be great asymmetry. A ruptured silicone implant is more difficult to determine and is referred as a silent rupture.
However, most agree today that if your Breast Implants are intact and you do not have problems such as Capsular Contracture or Implant Rupture, there is no need to remove Breast Implants that are intact and that you are happy with. The problem is that rupture of Silicone Gel Breast Implants is hard to detect. That is why the FDA recommends an MRI to check Breast Implant Integrity every 2-3 years. My personal view is that if your Breast Implants are soft, normal looking and there is no MRI indication of rupture, I recommend not removing them.
