A observational study published in Frontiers in Nutrition has shown that vitamin D deficiency is associated with an approximately 56% increase in the risk of head and neck cancers, including laryngeal and oral cavity cancers, after following more than 216,000 individuals for up to 10 years, with the risk particularly pronounced in those over 50.

A scientific study published in Frontiers in Nutrition has revealed that vitamin D deficiency may be linked to a significant increase in the risk of head and neck cancer, a finding that adds to a growing body of evidence on the protective role of this vitamin.

The researchers analyzed health data from over 216,000 people, comparing those with confirmed vitamin D deficiency to others with normal levels, with a follow-up period of up to 10 years.

The results showed that vitamin D deficiency increases the risk of head and neck cancer by approximately 56%, and this association included various types of tumors, such as laryngeal and oral cavity cancers.

The scientists also observed a direct relationship between the degree of deficiency and the magnitude of risk; the risk was lower in cases of moderate deficiency compared to severe deficiency. This association was more pronounced in individuals over 50 years of age, while it was not observed in younger groups.

The researchers emphasized that their study is observational in nature, and therefore does not definitively prove that vitamin D deficiency directly causes cancer, but it suggests that the level of this vitamin may be an important factor in assessing long-term health risks.

Vitamin D is an essential vitamin that affects multiple bodily functions, contributing to the health of bones, muscles, nervous system, and cardiovascular system, in addition to its potential role in preventing a number of chronic diseases.
