Debbie, there is an excellent article about gigantomastia here:
www.llli.org/llleaderweb/LV/LVJunJul05p62.html

Here is an excerpt:

>Gigantomastia is a rare connective tissue disorder, about which little is
known, that affects the breasts. Only a handful of cases have been
documented during the past century. Each case has some unique twist, but the
underlying denominator is increased breast tissue in gigantic proportions,
thought to be caused by sensitivity to prolactin. It appears to pass through
family lines, both from mother to daughters and from mothers, through their
sons, to granddaughters. Some women also experience insulin resistance,
their bodies becoming marked with brown spots.

A number of different cycles can signal the breast tissue to begin to grow
over abundantly: the onset of puberty, pregnancy, and/or birth. Not every
woman will experience all three.

At the start of puberty, some young females with little or no breast
development can grow three or more cup sizes within a few days.

This can also occur during pregnancy. Either at the onset of pregnancy or
between the 16th to 20th week of gestation, these mothers experience an
unusual growth of breast tissue, above and beyond what is considered normal.
With each subsequent pregnancy, the tissue growth continues from where it
left off the time before.<
