I hope it is not cancer. But radiation and chemo can do all kinds of weird things to tissue. But you do know that there is a law that says breast cancer patients are entitled to reconstruction of the affected breast in such a way that it matches the other as nearly as possible, and that the other breast is also eligible for adjustments in order to align with the implant. AND, the implant will not last forever, so at the time that is bursts, you are entitled to another implant, or to rebuild your breast out of belly fat. I have a fatty deposit at the side of my breast under the arm. When my real implant goes in, the deposit goes out, and my other breast gets lifted. There are some benefits to all this! Hope it turns out well for you.
