The treatment of pre axillary folds is dependent upon the cause of the problem. In some cases, it may be secondary to excess fat. Under these circumstances, the fat bulges outward from the edge of the patient bra and is very noticeable. In other cases, the bulge may actually be secondary to accessory breast tissue. When this situation occurs, the size of the mass may fluctuate with the menstrual cycle. The treatment of pre axillary folds is dependent upon the cause of the condition. Although your pictures illustrate the problem, they aren’t helpful in determining the actual cause of the condition. This usually requires a physical exam. During physical examination, breast tissue will be noted to be firmer and more fibrous than fatty tissue. When fatty tissue is encountered in the pre axillary region, liposuction will often provide correction of the problem. When breast tissue is encountered in this area, more aggressive procedures are usually necessary. In most cases, surgical resection of the tissue will prove to be necessary. If you’re concerned about pre axillary folds, consultation with a board-certified plastic surgeon is appropriate. This surgeon should be able to formulate a treatment plan that’s appropriate for your problem.
