I am 26 years old and my breast is very small. Is there is any exercise or type of food that may make it to grow or get bigger?

Hello and thanks for your post. Breasts grow and develop until about age 21-22. After that, the most effective way to make a breast cup size grown is through the use of breast implants. Best wishes, Dr. ALDO.

At the age of 26 it is very unlikely that your breasts will get any larger on their own, unless perhaps you gain a significant amount of weight.   Hormones can sometimes increase breast size but that is not a good reason to start taking hormones.  There are some non surgical options like the BRAVA system which you can research on the internet.  This system will increase breast size only modestly.  Your surgical options include Breast Augmentation with an implant or with fat.  These are all good options.  I wish you the best in your research.
