Tall people at greater risk of cancer, study says

Tall people are at a greater risk of cancer because they have more cells in their body, new research has suggested.A person’s risk of developing cancer increases by 10% for every 10 centimeters (4 inches) they are over the average height, the study said, because they have more cells which could mutate and lead to cancer.

Average height was defined in the study as 162cm (5 feet, 4 inches) for women and 175cm (5 feet, 9 inches) for men.The findings match with previous research, which has also connected height to an increased risk of developing a range of health problems including blood clots, heart problems and diabetes.
Leonard Nunney, a professor of biology at the University of California Riverside, analyzed previous sets of data on people who had contracted cancer — each of which included more than 10,000 cases for both men and women — and compared the figures with anticipated rates based on their height.
He tested the hypothesis that this was due to the number of cells against alternatives, such as possible hormonal differences in taller people, which could lead to an increased rate of cell division.A link was found between a person’s total cell number and their likelihood of contracting cancer in 18 of the 23 cancers tested for, the study says.
