How can I change my breast size as mine are shaped as a cone? (photos)

I recommend an in person consultation with a plastic surgeon to discuss your goals and be measured. After I measure and discuss goals with my patients, we then look at pictures of women (my patients) with similar measurements with different size and style breast implants and they choose what looks right for them. They also get to see what they would look like when the breasts have fully dropped and fluffed and in clothes. You get to see actual results and the surgeon's experience and not a virtual idea of what can be achieved. Women tell me that this process is very helpful in determining what size and style breast implant is right for them. Dr. Ted Eisenberg, Board Certified Plastic Surgeon and Author.

Dear Energetic833447,
tuberous breasts are not simply small or underdeveloped breasts. The appearance of the breast can range from mild to severe, and typical traits include: enlarged, puffy areola, rather wide spacing between the breasts, very little breast tissue, sagging, higher than normal inferior breast fold, and narrow base at the chest wall.The type of surgery best for you will depend on the severity of your condition.My preferred technique for tuberous breast correction involves a multistep procedure where the breast tissue is released in a radial pattern to prevent herniation into the areola and placement of a custom implant size is in the breast to allow appropriate expansion of the breast in the restricted dimensions. This can often be done in a single procedure but sometimes may require two surgeries.That said, it is best that you visit a board-certified plastic surgeon for an in person examination. Only after a thorough examination you will get more information and recommendations.

Although your photo is very limited, a breast lift should do well for you. Please discuss this with a plastic surgeon.

From the photo provided it appears you would have a nice result from a breast lift and implant. This would raise the position of the nipple, reduce the areola, add volume, and improve shape. See a board certified plastic surgeon near you to learn more.
