Do I have underdeveloped breasts? What are treatment recommendations? (photos)

You need a formal evaluation by a licensed plastic surgeon and expert in breast augmentations to determine what is best for you and your goals.
Proper breast enlargement is not a "cookie-cutter" procedure where the same technique is applied to every patient. Every woman who comes to my practice has unique needs and different goals for her breast augmentation. As a board-certified plastic surgeon, I always listen carefully to each woman's concerns and thoroughly discuss the key points of the procedure. I also take into account their overall height and weight, the size and shape of the underlying chest and ribcage, the tightness and elasticity of the skin, and the amount of natural breast tissue. Prior to the procedure, we discuss and make decisions regarding location of the incision, whether to place the implant under or over the chest muscle, and what type of implant to use (I offer multiple types of silicone gel breast implants, as well as saline implants).
My experience performing thousands of aesthetic breast surgeries in a wide anatomical range of patients enables me to achieve consistently beautiful and natural results that are customized to each patient’s body type and goals. These results are the product of extensive communication, meticulous planning, and skillfully executed surgery.
I suggest consulting with a board-certified plastic surgeon and expert in Breast Augmentation surgeries. - Dr. Cohen

Hello, thank you for your question. It seems like you can benefit from a breast lift with implants. A breast augmentation and a breast lift work hand and hand to enhance the overall shape and size of a woman’s breasts. These procedures are ideal for increasing the size of the breasts while restoring balance and youthfulness to a woman’s bust. Schedule an email, Skype or in-person consultation with a board certified plastic surgeon for proper evaluation.

Based on your photos, you do not appear to have underdeveloped breasts. Instead, you appear to have breast size and shape asymmetry. Depending on your goals, your breasts can be made larger with improved symmetry.It is best to consult a board certified plastic surgeon who is experienced in cosmetic breast surgery in person and discuss your goals and options after a physical examination.

Hello, based on your comment that your breasts are underdeveloped, I am assuming that you would like both breasts to be larger and not just the same size.  There are several options to increase your breast size and/or make the nipples perkier, such as implants, fat transfer, and breast lift surgery.  There are multiple experienced plastic surgeons in your province that should be able to provide an expert opinion on your options.

Thank you for your question and for your photos. Based on your photos provided, you do have size and shape asymmetry. I would advise you to schedule a consultation with a board certified plastic surgeon for a detailed examination. Different sized implants can be used to correct asymmetry.

Your breasts are asymmetrical in volume, shape, position and widely separated.  The technique I recommend is a lift using The Bellesoma Method.  This will reshape your breast tissue creating upper pole fullness without implants, elevate them higher on the chest wall and more medial to increase your cleavage.  Vertical scars are avoided, nipple sensation (in 95%) and the ability to breast feed are maintained.  At the same time or later, fat transfers can be performed if additional volume is desired.  Implants are not lifetime devices.  Fat transfers are permanent and incorporated into the body.Best Wishes,Gary Horndeski, M.D.

Thank you for your question and providing photos. I do believe at this time your breasts are fully developed. You have a size and shape asymmetry. I do believe both can be addressed. I would recommend you consult with a BC PS who can advise you of your options. Best of luck

KiennaI appreciate your current concerns, however it appears that you have modest asymmetry, the left breast a bit larger and lower than the right. Options include breast augmentation with different sized implants or possibly a small lift on the left breast with augmentation. Consult with a board-certified plastic surgeon in your area to explore the best options for you. Good luck.

I recommend an in person evaluation by a plastic surgeon to be measured and discuss your goals. After I measure and discuss goals with my patients, we then look at pictures of women with similar measurements with different size breast implants. My patients tell me that this process is very helpful in determining what size breast implant is right for them.

Based on your photos- you appear to be a candidate for Bilateral Mastopexy with slight reduction on the larger side to balance out asymmetry and Augmentation with implants if you desire more volume. I suggest that you seek an experienced Board Certified PS
