5 Factors That Determine Breast Shape

Updated for What factors contribute to breast shape in the first place? The factor that has the greatest influence on breast shape and size is genetics. Your DNA affects multiple characteristics, which in turn affect breast shape and size but also changes that take place over time. In addition to the direct effect on breast shape and size, your DNA also influences hormone production and levels, which also have an influence on breast development and changes that occur during menstruation and pregnancy. Your DNA comes from both parents, so just looking to your mother and her sisters will only provide part of the picture. The actions of genetics are influenced by environmental factors.

Genes for Breast Size Found

Researchers have identified seven genetic markers linked with a woman's breast size, according to a new study. While it's was known that breast size is in part heritable, the study is the first to find specific genetic factors that are associated with differences in breast size, the researchers said. In addition, two of these markers have previously been associated with breast cancer risk. This suggests some of the same biological pathways underlie both normal breast growth and breast cancer, said study researcher Nicholas Eriksson, of 23andMe, the genetic testing company that conducted the study. The study alone does not provide enough evidence to link breast size to breast cancer.

TNBC is associated with early recurrence of disease and poor outcome. Whether germline mutations in other breast cancer susceptibility genes also predispose to TNBC remains to be determined. Furthermore, variation in the 19p Thus, TNBC can be distinguished from other breast cancer subtypes by a unique pattern of common and rare germline predisposition alleles. Additional efforts to combine genetic and epidemiological data are needed to better understand the etiology of this aggressive form of breast cancer, to identify prevention and therapeutic targets, and to impact clinical practice through development of risk prediction models.
