Taller men and women are more likely
to develop cancer than their shorter peers, according to a major study that find
the new light on the link between height and the disease.
Previous
studies have shown the relation between height and cancer. That is to say,
taller individuals have a higher risk of developing different types of cancer,
including melanoma and breast cancer.
Dr. EmelieBenyi, a PhD student at Karolinska Institutet who led the study, believes this
is the first time the association between height and cancer has been studied in
men and women on such a large scale, although a link between height and cancer
development has been found in other studies.
He said that “One is that taller people have a larger number
of cells in their body which could potentially transform to cancer. It could
also be that taller individuals have a higher energy intake which has
previously been linked to cancer.”
Experiments in mice, genetically
engineered to make excess or very little growth hormone had also shown that
their cancer rates increase or decrease. “We know that in humans growth hormone
not only stimulates bone growth during our growing years, but stimulates cell
growth in general and blocks cell death. So the level of growth hormone someone
has could affect cancer risk by pushing up cell numbers,”.
