The silent vitamin deficiency experts say could increase your cancer risk over time

Key Points:
- Vitamin B12 deficiency, often silent and common among older adults, vegans, and those with digestive issues, may increase cancer risk by impairing DNA repair, cell growth, and inflammation control.
- Low B12 levels can lead to DNA copying errors over time, potentially raising the risk of cancers such as colorectal cancer, while unusually high B12 levels in blood may indicate existing cancers or other health issues rather than causing cancer.
- Excessive B12 supplementation is not proven to prevent cancer and might even support the growth of abnormal cells, so experts recommend using supplements only to correct deficiencies under medical supervision.
- Early symptoms of B12 deficiency, like fatigue, numbness, memory problems, and pale skin, often go unrecognized, highlighting the importance of preventive blood testing, especially for at-risk groups.
- Maintaining balanced nutrition, avoiding megadoses of vitamins, staying active, and following routine health screenings are key to reducing cancer risk and supporting overall health over time.
