How tall a person is as an adult (adult attained height) is determined by genetic and early environmental factors. It is also affected by a person’s nutrition, especially during important periods of growth and development, such as infancy or adolescence.
Studies have shown that taller people have a higher risk for some types of cancer. It is still not clear exactly how height increases cancer risk or if other factors, such as smoking or socio-economic status (SES), influence the risk. It may have something to do with hormone levels in childhood, adolescence or adulthood. Taller people have more cells and this may lead to a greater chance for mutations to occur, which could result in cancerous cell changes.
A higher cancer risk associated with taller adult height has been reported for several cancers.
