Are breast pumps a viable breast enlargement solution?

Temporary breast pumps are not a viable breast enlargement solution. In fact, overuse of this type of breast pump may cause broken blood vessels and other health issues.
The Brava system certainly does work. But there are some significant drawbacks:
It's expensive. At about $2500, cost is a significant factor for most people.
It works slowly. The Brava system needs to be used for about 6 months for maximum results.
It should be worn 12 hours per day. Even though the Brava breast pump is fairly low-profile, rather like a padded bra, many people find this recommendation difficult to follow.
Gains are modest. On average, women gain from 1/4 to 1/2 cup even after following all the guidelines faithfully.
