The Role of Genetics in Breast Sizes
What is the link between
genes and breast size? Well, some studies show that your genes play a big role
in determining the growth of your breasts. The characteristics of your breasts
can come from either side of your family. This means that your father’s genes
could play a part in determining the size of your breasts, just as well as your
mother’s genes. The following are the two main genetic links to breast size.
•
Genes stimulate the levels of certain hormones in the body and some of
these hormones are responsible for the abundance of the breast tissues such as
estrogen and testosterone. These hormones play a big role in regulating the
volume of the breasts. Estrogen is specifically in women, and an increase in
its production leads to an increase in the size of the breasts, which increase
s the bra size. Testosterone, on the other hand, is exclusive to men and an
increase in its production in the body of a woman plays a big role in reducing
the growth of breasts. Women with bigger chests tend t have a higher estrogen
receptor gene in comparison to those who have smaller ones (ER+).
•
In addition to this, genes also play a part in determining the texture
of your skin, which in turn affects the appearance of the breasts. The females
in some families have breasts that are more firm and supple in comparison to
the rest. The firm and supple nature of breasts play a big role in relation to
the breast size.
Therefore, the genes in
your family determine the original size of your breast wholly. However, breast
cancer can be passed down through generations because of the same genes that
are responsible for the growth of breasts. For example, some people acquire
genomes from their parents that have abnormalities, which lead to certain
subtypes of breast cancers. Some studies show that the density of the breast
increases the chances of contracting breast cancer, but only in women who were
lean when young. Some of these studies contradict, while others are very vague.
The similarity in all of them is that there is a strong relation between the
density of the breast (That is a result of the gene present in the body) and
the possibility of contracting cancer.
