Combining breast surgery and liposuction is perfectly reasonable. You don't mention the areas for liposuction, but I will assume you are talking about body areas. That particular combination is a common one and should not be a problem. Good luck!
Your question is a broad one, and I have to assume you're asking whether liposuction done elsewhere on the body can be done at the time of breast lift. Yes, liposuction is frequently done along with other procedures such as breast lift.
