How should I remove accessory breasts?

I want to wear sleeveless tops, but I'm really worried because I have a lot of fat under my arms and on my arms.

It also shows sagging like accessory breasts, so I gently massage it, and

Is liposuction the sure method for removal?

It stands out even more when I bring my arms together, so I end up putting my hands on my hips.

My upper body looks a bit bulkier, too... There are more than a few places I want to fix.
