Women with larger breasts are more likely to develop breast cancer, scientis
ts believe
A study of more than 16,000 women found those with a larger bra size were at
greater risk of the disease.
The link could be down to the sex hormone oestrogen that can trigger the gro
wth of mammary glands and tumours.
The researchers found seven genetic factors significantly associated with br
east size - three of which are strongly correlated with mutations already li
nked to breast cancer.
Dr Nicholas Eriksson said: "One of the variants is known to regulate the exp
ression of the oestrogen receptor gene which plays a vital role in breast gr
owth and in the majority of breast cancer cases.
"Another one of these mutations is located in a region of the genome that of
ten shows abnormalities in people with a certain subtype of breast cancer."
He used data from his California-based personal genetics company 23andMe to
make the first concrete link between breast size and breast cancer risks.
His findings, published online in BMC Medical Genetics, are based on the par
ticipants answers to survey questions including bra cup size and bra band si
ze and comparing them with genetic data on millions of mutations.
Dr Eriksson said: "Social norms and preferences aside, it turns out that bre
ast size matters - but not quite in the way you think.
"The paper shows genetic factors influence whether women have double As or d
ouble Ds.
"This might sound a bit frivolous at first but our research uncovered surpri
sing connections between the genetics of breast size and the genetics of bre
ast cancer.
"In our case, no one's personal space was violated - all of our data was sel
f-reported by female 23andMe customers of European descent who have opted in
to research and filled out an online survey.
"We specifically asked about bra cup size as an approximation for breast siz
e using a 10-point scale ranging from 'Smaller than AAA' to 'Larger than DDD
.'"
His team also took into account age and breast-related surgeries including a
ugmentation or reduction.
Dr Eriksson said: "Most of the genetic factors we identified for breast size
lie in regions of great importance for breast cancer.
"These findings show some of the same biological pathways underlie both norm
al breast growth and breast cancer.
"This isn't a huge surprise if you think of cancer as unrestrained growth. B
ut the relationship between breast size and breast cancer is complicated.
"Some studies have found that larger breast size as a young woman is associa
ted with a slight increase in breast cancer risk, but only in women who were
lean at a young age.
"The genetic factors we found aren't enough to explain this association, but
support the idea that breast size and breast cancer are related."
The analysis also controlled for age, genetic ancestry, breast feeding statu
s and pregnancy history.
While breast size is heritable the study is the first to identify genetic va
riants linked to differences.
Dr Eriksson said: "These results provide insight into the genetic factors un
derlying normal breast development and show that some of these factors are s
hared with breast cancer."
He added: "While the topic of breast size raised a few eyebrows when we firs
t put out the survey - some thought it was too personal or couldn't be serio
us science - this paper demonstrates important scientific insights can come
from the most unlikely of places.
"Although the connections between these genetic factors - breast size and br
east cancer aren't fully understood - our findings give clues to the functio
n of some of these genes and regions that might be useful in combating breas
t cancer." |
