Is Smart Lipo on Arms Safe for Patient Who Had Breast Cancer?

Congratulations on being cancer free! I treat many breast cancer patient's and I can understand your desire to look and feel better.  Breast cancer in and of itself is not a contraindication to having smart Lipo or even regular liposuction.  The 2 items in your history that are concerning are axillary lymph node dissection and radiation. The combination of these 2 procedures really makes any Liposuction on your breast cancer side risky.  Lymphedema is a very difficult problem to solve and in this case I do not believe the risk, is worth the potential gain.  Sorry!  Again congratulations on being cancer free!

If you have a previous history of lymphedema, there is the potential that laser liposuction can make that worse and, therefore, I would not advise you to have laser liposuction. An alternative might be Thermage treatment, a non-invasive approach that may also tighten the skin.
Although liposuction can be used to treat lymphedema. Generally liposuction is not used for lymphedema and this is one of those conditions where the treatment could either make the problem slightly better or markedly worse. I would advise against it.
