Does Sucking and Pressing the Breast Increase the Size?

Breast size is primarily determined by genetics, body weight, and hormonal influences, not by external actions like sucking or pressing. However, certain conditions and devices can temporarily affect breast size:
BRAVA Device: This is a suction device designed to apply gentle, consistent pressure to the breasts over extended periods. It can lead to temporary increases in breast size due to swelling and stretching of the tissues but it is primarily used in preparation for fat grafting procedures.
Suckling During Nursing: Breastfeeding can lead to temporary increases in breast size due to milk production and hormonal changes. This enlargement typically subsides after breastfeeding is stopped.
Temporary Inflammation from Trauma: Any trauma or pressure can cause temporary swelling or inflammation, leading to a transient increase in size. This is not a sustainable or safe method for breast enlargement.
For permanent changes in breast size, surgical options like augmentation or fat grafting are the most reliable. Consult with a plastic surgeon to explore safe and effective options tailored to your body and goals.

The short answer is no. Only breast enhancement with an implant or fat transfer increases the size of the breast. The techniques you ask about may temporarily increase the size due to stimulation and swelling but this not guaranteed and certainly not lasting.

Sucking and pressing does not increase breast size long term. You may notice a temporary increase in size from swelling, but it does not last. If you're considering breast augmentation, consult a board-certified Plastic Surgery. Your breasts can be augmented with your own fat (fat grafting), an implant, or both.
