Selenium, or selen, is a powerful trace mineral known for its potent antioxidant properties and ability to support the inhibition of malignant cell growth. Dubbed the “King of Cancer Fighters,” this essential nutrient plays a crucial role in overall health, especially for the elderly, despite the body requiring only a small amount daily.
1. What is Selenium and Why is it Called the “King of Cancer Fighters”?
Selenium is an essential trace element that plays a vital role in various bodily functions. A prominent study in Qidong, China, revealed that reasonable selenium supplementation could reduce cancer-related mortality by up to 50% and decrease the risk of liver cancer by 49%.
According to TS.DS Nguyen Trung Tuong (QTN Medical System), selenium protects the body through four crucial mechanisms:
- Immune Boosting: Selenium maintains the efficient activity of NK cells and T cells, the forefront forces in detecting and destroying cancer cells.
- Superior Antioxidant: As an essential component of glutathione peroxidase and thioredoxin reductase enzymes, selenium helps neutralize free radicals and protects cells from damage.
- Inhibiting Metastasis: Selenium contributes to suppressing the invasion and spread of tumors.
- Reducing Side Effects of Cancer Treatments: Cancer patients supplemented with the right dose of selenium often experience significant improvements in hair loss, nausea, and mouth ulcers.

2. Selenium Deficiency: A Silent Enemy of the Elderly
In older adults, the ability to absorb selenium from food decreases over time. Additionally, chronic conditions such as diabetes, cardiovascular disease, and Alzheimer’s also deplete the body’s selenium reserves.
Selenium deficiency in the elderly can lead to:
- Immune system weakness and increased susceptibility to infections.
- Heightened risk of cancer and cardiovascular disease.
- Dry skin, accelerated aging, and wrinkles.
- Decline in memory and slower reflexes.
