What can cause a 25 year old women's breast grow rapidly?!

In females the development of breasts is due solely to the sex hormone Estrogen!.

A combination of neonates (from the mother), hypertrophy (excessive increase) of the chest muscles, fat accumulating in the chest tissue, and loose skin result in this happening in men and women!.

Apart from Pregnancy, breast size increase and decrease can be due to any of the following factors:

- Puberty
- Weight loss or gain
- Increase as a response to the hormone prolactin
- Breastfeeding
- The menstrual cycle
- Premenstrual water retention
- As a side effect of the contraceptive pill
- Increase or decrease in levels of estrogenWww@Answer-Health@Com
