Cancer risk has been found to increase with height in both Swedish men and women, according to research presented today at the 54th Annual European Society for Paediatric Endocrinology Meeting. This long-term study is the largest carried out on the association between height and cancer in both genders.

Researchers from the Karolinska Institutet and University of Stockholm examined 5.5 million men and women in Sweden, born between 1938 and 1991 and with adult heights ranging between 100 cm and 225 cm. They followed the group of individuals from 1958 or from the age of 20 until the end of 2011, and found that for every 10 cm (4 inches) of height, the risk of developing cancer increased by 18% in women and 11% in men. Additionally, taller women had a 20% greater risk of developing breast cancer, whilst the risk of developing melanoma increased by approximately 30% per 10 cm of height in both men and women.

Previous studies have also shown the same association between height and cancer. That is to say, taller individuals have a higher risk of developing different types of cancer, including breast cancer and melanoma. However, this association has never been studied in men and women on such a large scale before. "To our knowledge, this is the largest study performed on linkage between height and cancer including both women and men," said Dr Emelie Benyi, a PhD student at Karolinska Institutet who led the study.
