Manufacturers claim the pumps are a miracle treatment for women who dream of fuller and supple breasts without the pains and health problems associated with surgery. Breast enlargement pumps consist of a pump attached to a specially designed cups or cylinders. Each cup or the cylinder is attached to the breasts and manually pumped up to a good pressure. This procedure is repeated for 15 minutes twice a day to produce the best results.

According to the manufacturer, the external pressure creates a suction by which the breasts are pulled outward. This process increases vacuums of fat and fluids and makes them flow into the breast tissue cells causing them to enlarge. Pumps also helps to build and expand the mammary gland tissue by stimulating a balanced natural hormone level and encourages increased production of collagen to provide firmer breasts.

Some manufacturers claim that regular stimulation of the breast tissue by pumps induces the pituitary gland to increase the production and release of the female hormones responsible for breast growth. Besides, regular stimulation and the gentle stretching of the breast repeatedly induces new cellular growth and enlarges the breast. The process works in the same manner as regular exercising does for muscle growth.

Whether the breast enlargement pump is effective in the enhancement of the breasts is still a matter of speculation. Many doctors deny any role of pumps in the process of breast enlargement. The supposed increase in the size, doctors say, is purely a placebo effect. Secondly, the elastic nature of the skin responds to the prolonged pumping by stretching itself to an extent as to give the effect of an enlargement.

Some women claim that prolonged use of pumps has increased their breast by 2 cups. Some have reported an increase by a cup size within three weeks. The use of breast enlargement pumps may harm or damage the breast tissue, so before deciding on the use of pumps it would be worth the effort to investigate all information thoroughly.
