Mr. Zhang listened carefully to the expert’s words and was puzzled.

First, people with white hair are less likely to get cancer, is it true or false?

This myth stems from a Harvard study showing researchers that leukoplakia is actually a protective mechanism for the body, suggesting that melanin-producing stem cells are destroyed and destroyed. Cleared, can reduce the risk of cancer.

Is this true?

In fact, this study originated from a 2009 mouse model study to investigate hair graying, this study did not have data on the incidence of cancer< /strong>, the so-called “grey hair reduces the risk of cancer” is just a misreading of foreign media reports, leading to wrong conclusions. And based on the reality, the elderly are far more likely to develop cancer than the young, which contradicts the conclusion.
