TOKYO BUST EXPRESS REVIEW: HOW GENES INFLUENCE BREAST SIZES

Are bra sizes pre-determined at birth?
You might notice that the women in your family have similar breast sizes. You might be wondering, what exactly determines the shape, feel, and size of your breasts. So many factors determine the size of a woman’s breast such as the diet, age, breast surgeries, active mammary glands, bra band size, and even change in hormones. Most people have no idea that genetics plays a big role in determining the size of the breasts of a woman. This read aims at shedding some light on how genes influence the growth of the breasts.
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.
