Aggressive lipo? How many cc's have to be removed from the abdomen to have it considered to be an aggressive treatment?

Hello,
Aggressive liposuction is less about total volume (that would be known as 'high volume liposuction'), and more about what was left behind. Without having seen you before and after surgery, and without high quality, non-selfie photos, nothing can be said about your surgery.  I can tell you that if your surgeon was an ABPS certified/ASAPS member surgeon with at least a decade of experience in specializing in body contouring procedures, you can likely trust what he said.  Best of luck!

There is no definition of aggressive liposuction.
In my opinion attempting to remove more than 75% of the fat in the single area is about when I would refer to as aggressive liposuction.
When that much fat is removed there may be some increased blood loss see in mixed with the fat and fluid that comes from the container.
Patients are often substantially more sore for several days after the treatment then when liposuction is done in a more gentle fashion.
Aggressive liposuction it takes about twice as long as gently performed liposuction.
Patient's weight or BMI are irrelevant to some degree, Fat distribution is by far more important when assessing a patient for liposuction. You 
It's a completely subjective term so you will not get a yes or no answer to your question.
In the end all that really matters is what your results are like and that the procedure was done safely.
