Liposuction is a surgical procedure designed to improve body shape and contour by removing fat deposits. Common locations for liposuction include neck, abdomen, inner and outer thighs, flanks, back and knees. Liposuction is also used to treat male breast enlargement (gynecomastia) which frequently occurs in teen and adult males. Liposuction can restore balance to bodies that are physically fit but out of proportion in a few areas.
