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

I had breast cancer 11 yrs ago; stage 1 NO node involvement; radiation and lumpectomy with node dissection (don't know how many removed). Had minor Lymphedema 1-2 yrs after surgery.My arms are now normal, equal in size, no swelling for past 9 years. I'm considering Lipo or Smart Lipo to reduce arm size and tighten area. Arms are 12", NO bat wings but some fat and sagging. I'm 57, 5'4", 140 lbs. and have good skin tone.Is there a contraindication for Smart Lipo in my case? Could it trigger lymphedema? I heard that lipo is now used to TREAT lymphedema. Thoughts? Thanks!
