Usually genetics or the amount of growth hormones consumed during their lifetime from animals that were fed growth hormones.
It is nomal for some women for their breasts to get slightly larger right before their period.
This is a very debatable topic. For one the breasts of women vary in size and have to do with the genes handed down. Some women are born with big breasts, however the main topic that is debated upon is that so many women get boob jobs that it seems that breasts have become larger over the years. So if you are counting silicon breasts into your statistics then i would have to say yes because the percentage of women with boob jobs is much higher than the percentage of women with small breasts.
Why do some men want to grow breasts like women
Not every guy likes large breasts on females. Each male has their own likes with the female body. Some men may prefer women with small breasts while others may not like breasts at all.
Some pregnant women lose their balance because their posture changes. Their breasts become larger as well as their stomach and the curvature of the back is increased. All of these factors affect a women's sense of gravity.

Women want to have big boobs because men want women to have big boobs. It's really that simple. Big boobs are uncomfortable and cumbersome, sometimes even painful. I very much doubt that any woman would choose big boobs over small ones, if it weren't for the fact that men prefer big ones. The real question is, why do MEN like big boobs?
