is it normal to have a 42F bra size at the age of 16?

Thanks for your inquiry and heartfelt question.  I do not like to answer questions as normal or abnormal.   Every one is unique and a combination of their genetics and environment influences their bodies and health. I would make sure you see you family doctor to make sure there is no health reason why your breasts are so big.  Good Luck.

Hi Sillyartistic.F cup breasts are rather large, and there may be some important medical conditions that may be the cause, or it just may be you.If they bother you, discuss this with our parents, and you may be a good candidate for a reduction.Se

Hello sillyartistic, thanks for your question. I am very glad to hear you have begun exercising, I always encourage my patients to try to try to get their BMI (body mass index) below 30 prior to any surgical procedure. Having a chest diameter of 42 would tend to indicate some of the volume of your breast is due to excess weight, however having a F cup is quite large for any age. We often try to wait until the breasts are fully developed before considering reduction surgery. This can be from 18-20, as a portion of the breast tissue is fatty tissue any weight loss would help reduce the breast size, although the breasts are unlikely to drop several cup sizes.  It would be good to see your Pediatrician who can refer you to a Plastic Surgeon who can assess your breast size and discuss aspects of breast reduction surgery as well as timing and the positive aspects of additional weight loss.  I wish you the best of luck and am very excited about your exercising!
