High people at greater risk of cancer, says the study

High people have a greater risk of cancer because they have more cells in the body, new research has suggested.

A person’s risk of developing cancer increases by 10% for every 10 centimeters (4 inches) they are above average height, the study said, as they have more cells that can mutate and lead to cancer.

Mean height was defined in the study as 162cm for women and 175cm for men.

The results match previous research, which has also linked height to increased risk of developing a number of health problems including blood clots, heart problems and diabetes.

Leonard Nunney, Professor of Biology at the University of California Riverside, analyzed previous sets of data on cancer contractors &#821

1; each included more than 10,000 cases for both men and women – and compared the expected prices 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 higher humans, which could lead to increased cell division.

A link was found between a person’s total cell number and their likelihood of getting cancer in 18 of the 23 cancer samples tested for, said the study.

Research also found that the increase in risk is greater for women, with higher women 12% more prone to cancer and higher men 9% are more likely to do it. These findings matched Nunney’s predicted prices, using his models, 13% for women and 11% for men.

Colon and kidney cancer and lymphoma were among the types of cancer for which the correlation was strongest.

“We have known that there is a link between cancer risk and height for quite some time – the higher someone is, the higher the risk of cancer,” told Georgina Hill of Cancer Research UK at CNN.
“What we have not been sure is why – if it only depends on a higher person having more cells in the body or if there is an indirect link, like something to do with nutrition and childhood, “added Hill, who was not involved in the study.

She said that the study provides good evidence of the “direct effect” theory that the total number of cells actually causes the link.

“The method is good – they took data from major studies, which is important, and they looked at many different categories of cancer.”

However, she noted that the increase in the risk of developing cancer is small compared with the effects lifestyle changes may have.

“There was only a slightly higher risk and there are more important actions that people can take to make positive changes, [such as] stop smoking and maintain a healthy weight,” she said.

Two of the types of cancer tested for thyroid cancer and melanoma proved more susceptible to an increased risk than expected and Nunney suggested in the study that other factors could be in play in these cases, geography.

“There are no obvious reasons for these exceptions, although the author speculates that cell turnover rates may play for melanoma,” said Dorothy C. Bennett, head of the Molecular and Clinical Sciences Research Institute in London, CNN . Bennett, who was not involved in the study, explained that pigment cells, the source of melanoma, split up and replaced a little faster in higher humans.

“But I can not currently think of any reason that this should be so, but no other clear reason for the higher correlation with the height,” Bennett said.
