Where boobs grow biggest

US women were found to have a significantly larger mean breast volume than women from other nations, while Filipino women were found to have the smallest.

Women from Canada, Ireland, Poland and the UK were also found to have some of the biggest breasts in the world. On average South African women wore a B-cup, compared to the E and F cups of US women.

Researchers used European standards for cup sizes.

Researchers excluded women with breast implants, those who were pregnant, breast-feeding or had been pregnant in the past 12 months from the study.

"The analysis of the results also showed that the correlation between a woman's body weight and the size of her breasts is quite different from one country to another," the study added.

"A typical woman born in the US or Canada has a very large breast volume, regardless of her body weight."
