Uncomfortably large breasts can be caused by a number of biological and lifestyle-related factors, such as: Hormonal changes. Pregnancy and breastfeeding can play a role in developing overly large breasts. Genetics.
A study published in the journal, The Royal Society Publishing, found that women with larger breasts and smaller waists were more fertile and thus, had a high reproductive potential—thanks to the higher levels of the female reproductive hormone, estradiol, in them.
