Does your height affect your cancer risk?  A new study suggests that it does.

In a survey of almost 21,000 postmenopausal women, researchers found that a woman's risk of developing a number of cancers, including breast, colon and skin cancer, increased with her height.  Researchers who conducted the study, which was published in Cancer Epidemiology, Biomarkers & Prevention, say that they don't wish to alarm folks who walk on the tall side.  Rather, they hope that this information could be used to help doctors zoom in on the hormones and growth factors that influence height and it's influence on the development of cancer.

“We know that cancer is a disease in which hormones and growth factors modify things,” said Geoffrey C. Kabat, a senior epidemiologist in the department of epidemiology and population health at the Albert Einstein College of Medicine of Yeshiva University in New York. “Height itself is not a risk factor, but it really appears to be a marker for one or more exposures that influence cancer risk.”

So why would taller folks have a higher cancer risk?  Hormones?  Greater surface area?  More cells (so a greater likelihood that some of those cells might be cancerous?) It's anyone's guess right now and obviously a subject that needs more research.
