Breast augmentation is a surgical procedure that is performed to enlarge, enhance the shape, or balance the size of your breasts. Breast reduction is a surgical procedure that is performed to reduce the size and weight of your breasts. A male breast reduction (gynecomastia surgery) is a procedure designed to remove excess fat and gland tissue of the breast.
Breast augmentation is a surgical procedure that is performed to enlarge, enhance the shape, or balance the size of your breasts. The surgery involves the placement of implants behind the breast tissue or below the chest muscles. The type of breast implant, size and placement will be decided upon by you and Dr. Mahoney at your consultation.
Factors such as pregnancy, weight loss, gravity and aging produce changes in a woman's breasts that cause them to lose their shape and begin to sag. If your breasts have lost volume over time, breast implants may be considered in conjunction with a breast lift to improve the overall breast enhancement.
Breast reduction is a surgical procedure that is performed to reduce the size and weight of your breasts. If you experience a variety of problems from heavy breasts, your surgery may be an insured service by OHIP. In many cases, patients benefit from liposuction of the lateral chest wall (sides of the breasts) to improve the overall contour and results of surgery.
Breast reconstruction is a surgery that involves creating a breast which has been removed in part (lumpectomy) or in its entirety (mastectomy). This is usually secondary to treatment of cancer or prophylactic removal of the breast for patients who are at high risk of developing breast cancer (BRCA gene mutation).

I had a breast reduction done by Dr. Mahoney last summer. If you have a look at her website, it's simple and to the point. When you meet with her, she is very personable and honest. I have recommended many people to her simply because she was professional, caring and wanted the best for me. Her experience in this field shines through with the type of incisions she does during surgery. My life has changed tremendously since I had this surgery and I would do it 100x again. Thanks again!

I recently had my breast reduction performed by Dr. Mahoney and I couldn't be happier with the results! It has almost been a week since surgery and I am still in awe of what an amazing job she did!
Dr. Mahoney came highly recommended to me by various other physicians I spoke to when I was deciding whether or not to get this procedure done. That alone says a lot.
From our first appointment through to my post-surgery follow up, she made sure to answer all of my questions and was extremely thorough in explaining the procedure, what to expect afterwards and was very diligent in ensuring I had a safe

I cannot say enough good things about Dr. Mary Helen Mahoney. She changed my life, and I am forever grateful. She is kind, patient and caring. She truly listens to you and makes you feel at ease. She is realistic with the outcomes and is honest. Dr Mahoney told me prior to my surgery that she was going to personally walk me in there and hold my hand until I fell asleep, and that is exactly what she did. A nurse offered to hold my hand instead and she declined. It has been 4 years now, and I am still just over the moon. Thank you Dr Mahoney!! <3
