Can Selenium Deficiency Cause Cancer?

Cancer is just a chapter in our lives and not the whole story.

Cancer is a global health concern and scientists are exploring various factors that may contribute to its development. While there is no single cause of cancer, scientists are beginning to find out the link between nutrient deficiencies and cancer. Selenium, a trace element found in the body, has gained much attention due to its antioxidant properties and potential impact on cancer risk.

Now let’s go over some stats related to selenium deficiency and cancer. Forty nine observational studies involving 1 million people showed a 31% lower risk of cancer and a 45% lower risk of cancer deaths in people with high selenium levels compared to those with low levels of selenium in the body (Source).

In this blog, we will explore the relationship between selenium deficiency and cancer, focusing on insights gained from hair mineral analysis.

Understanding Selenium and its Importance

Selenium is a micronutrient that is obtained through dietary sources like Brazil nuts, seafood, poultry, whole grains and eggs. It functions as a cofactor for several enzymes involved in antioxidant processes, preventing cellular damage caused by free radicals. Also, Selenium plays a crucial role in properly functioning the immune system and regulating inflammation.

Low selenium levels also cause cardiovascular disease and infertility. The signs of selenium deficiency are depressed mood, anxiety and confusion. One of the major causes of selenium deficiency causes is consuming foods with little selenium content.  

Selenium deficiency and cancer risk

Scientists have explored the potential association between selenium deficiency and cancer development. Researches show that inadequate amounts of selenium in the body cause an increased risk of different types of cancer. Here are some key findings:

• Colorectal Cancer:

Multiple studies have shown the inverse relationship between selenium levels and the risk of colorectal cancer. Selenium’s antioxidant properties may help reduce DNA damage and inhibit tumour growth in the colon and rectum.

• Prostate Cancer:

Research suggests that selenium plays a crucial role in protecting the body from prostate cancer. Low selenium levels are linked to an increased risk and aggressive forms of prostate cancer.

• Lung Cancer:

Studies examining the link between selenium and lung cancer have produced considerable findings. Lung cancer is caused due to low selenium levels. Hair mineral analysis is useful in this regard, as it suggests supplements and diet plans to increase intake of selenium-rich foods to protect your body from lung cancer.

• Other Cancers:

Limited evidence suggests that low selenium levels could be the cause for skin, bone and pancreatic cancer. Researches are in the process of determining the link between selenium deficiencies and these types of cancers.

Hair mineral analysis: A window into selenium status

Hair mineral analysis is a non-invasive diagnostic tool that provides insights into a person’s mineral and heavy metal levels. Analyzing a small hair sample makes it possible to determine the body’s mineral status for an extended period. Selenium levels in the hair can be an indicator of selenium levels in the body, as the hair reflects the mineral composition of the blood during hair growth.

Several studies have utilized hair mineral analysis to investigate selenium status in individuals with cancer. These studies have shown that individuals with certain types of cancers show low selenium levels in their hair when compared to other healthy individuals. However, it is important to note that hair mineral analysis is not a definitive method of detecting cancer or selenium deficiency. It serves as an additional tool that assists healthcare professionals and researchers in evaluating an individual's overall health.

The Importance of Adequate Selenium Levels

Maintaining optimal levels of selenium for overall health and potentially reducing the risk of cancer is advisable. A well-balanced diet of selenium-rich foods can adequately intake this essential mineral. Also, it is important to note that excess selenium in the body could cause adverse effects. It is also advisable to get selenium through dietary sources more than from supplements unless recommended by a health care professional.

Conclusion

The potential link between selenium deficiency and cancer development is a subject of ongoing investigation. Many studies show that selenium does play a role in cancer prevention, and low selenium levels might cause cancer. Selenium must be viewed as part of an overall balanced diet that promotes good health and wellness rather than a standalone solution for cancer.  

At Ginerva, we provide hair mineral analysis tests that will help diagnose selenium deficiencies in the body and suggest diet plans and supplements to help balance selenium levels in the body. You must consult health care professionals regarding your nutritional needs and any concerns you may have regarding selenium deficiency and cancer risk. Additionally, maintaining a healthy lifestyle, doing outdoor activities like exercise and eating a well-balanced diet could contribute to your overall well-being and reduce the risk of cancers.
