What Is the Association Between Vitamin a and Lung Cancer

What Is the Association between Vitamin A and Lung Cancer?

• Vitamin A supports the methylation of DNA and controls gene expression in the cell. Insufficient DNA methylation is a salient characteristic of cancerous cells.

• Vitamin A enhances the lungs' ability to produce carcinogen- degrading enzymes that can detoxify airborne carcinogens and decrease the risk of lung cancer.

• Vitamin A deficiency increases the risk that epithelial cells in the trachea and bronchi will transform into cancerous cells.

• Toxic chemicals from cigarette smoke induce the lungs to produce free radicals, which can deplete vitamin A contents stored in pulmonary cells. Vitamin A deficiency increases the risk of lung cancer.

• Vitamin A. A meta-analysis of 19 research articles studied the association between vitamin A and lung cancer in 10,261 participants. The result confirmed that sufficient dietary intake of vitamin A reduced the risk of lung cancer.
