Can selenium supplement prevent cancer?
Hello!

Selenium is closely related to cancer. Experiments show that selenium deficiency is closely related to gastric cancer, liver cancer, cervical cancer, rectal cancer, prostate cancer, ovarian cancer and many other cancers. Selenium supplementation is beneficial to reduce the incidence and mortality of cancer, especially liver cancer, prostate cancer, colorectal cancer and lung cancer.

The role of selenium

1, improving immune function and anti-cancer ability. The decline of immune function is one of the important factors of tumor occurrence and development. Studies have shown that selenium not only significantly affects the immune system and regulates the physiological functions of the body, but also promotes the production of antibodies by some lymphocytes, so as to increase or maintain normal blood immunoglobulin.

2, improve the body's antioxidant capacity. There are extensive antioxidant imbalance and excessive harmful free radicals in cancer patients. Selenose can effectively remove lipid peroxide and hydrogen peroxide.

3. Blocking tumor angiogenesis and preventing tumor recurrence, metastasis and growth depends on establishing vascular system and taking nutrients from human body to meet the needs of its rapid growth. Selenium can promote the formation of "anti-tumor angiogenesis inhibitor", thus inhibiting the formation and development of "tumor angiogenesis network" and cutting off the nutrient supply channels of tumor cells.

It is a complex process of multi-factor participation, multi-gene change and multi-step evolution to inhibit the occurrence of tumors at the molecular level. Selenium can regulate gene expression and protein synthesis related to tumor biological characteristics in many ways, thus inducing tumor differentiation and inhibiting its growth.

4. Selenium can enhance the curative effect of radiotherapy and chemotherapy, but the tumor hypoxia cells in human body are not sensitive to radiotherapy and chemotherapy, which often becomes the root cause of the incurable tumor. Selenium can repair tumor immature blood vessels, reduce tumor hypoxic cells and improve the curative effect of radiotherapy and chemotherapy.

In 2003, the US Food and Drug Administration (FDA) confirmed that selenium is an anticancer agent, which opened up a new way for us to overcome the "difficulties" of cancer and brought new hope.

Hope to be adopted, thank you ~ ~
