Many studies have shown taller women have an increased risk of breast cancer [50,130,190]. A pooled analysis that combined data from seven prospective studies found women over 5'3" have a slightly higher risk of breast cancer than women under 5'3" [130].
One reason for this increase in breast cancer risk may be because of the growth spurt tall women can have in their youth. Growth spurts may occur due to higher levels of hormones (such as IGF-1) or other growth factors. During a
growth spurt, rapid cell growth and hormone changes occur that may impact breast cancer risk later in life.
