Increased risk of cancer in large people due to the number of cells: Study, Health News



Larger people have a higher cancer risk that they have "hardwired," partly because they have more cells for the disease, a study on Wednesday said.

Researchers in the US studied populations on three continents and found that the risk of contracting cancer increased by 10 percent per 10 centimeters in both men and women.

Cancer develops when the body's normal cell growth controls cease to function, resulting in the formation of abnormal cells that manifest as tumors. 19659002] A study published in the journal Proceedings of Royal Society B suggests that the risk of multiple cancers is likely to be greater in larger humans because they have more cells and therefore more ability for these cells to become cancerous.

This means that this extra risk is "hard-wired" and can not be reduced in an obvious way, "study author Leonard Nunney of the University of California Riverside told AFP.

It's tho that larger mammals like elephants and Giraffes ̵

1; whose bodies have a much larger number of cells than smaller creatures – have developed additional protective measures against cancer,

but there is no evidence that this affects individuals within individual species, such as humans.

The average body size varies between regions, but in the United States, men are 176 cm tall and women are 162 cm.

Scientists have known for a while that larger people tend to. At a higher risk of cancer, Nunney's study of human populations in the United States US, Europe and South Korea stated that this may be due to is ckzuführen that they have more cells in which something can go wrong.

Especially in larger people, an increased risk of melanoma was noted because they have a higher rate of cell division – and, simply, more skin – than people of average height.

However, the risk of gastric, oral and cervical cancer in women did not appear to be affected by height.

NATURE VS NUTURE

While height is largely determined by the genes of an individual, Nunney said that childhood environment also has likely effects and associated cancer risks.

"Environmental and genetic factors in childhood both have a strong influence on adult height," he said.

"There is no reason to believe that their impact on cancer risk would be different because the driver is the number of cells and not why or how an individual has landed with a certain number of cells."

Obesity in adulthood is known to increase an individual's cancer risk, but for a completely different reason.

As the number of cells increases, obesity changes the size of these cells, rather than creating more.

"So we can expect the cause of any obesity-related increase in cancer risk to be different from the height effect," said Nunney.

He suggested that there should be more research into why large mammals do not appear to be at increased risk of cancer if they have built-in cell protection that could replicate in humans.

Although the results showed that a person's risk of cancer is about to increase With his height, Nunney said that larger people do not need to panic because their height is far from the only or leading risk factor for the disease.

"I do not think extreme measures are generally needed: the effect is statistically and relatively small for most people," he said.

However, he added that "unusually large" people could benefit from additional care: a 229 cm tall man has twice the risk of developing cancer than a five-foot-two-inch
