2. Selenium competes with carcinogens. Some carcinogens must be metabolized into intermediate products in the human body before they are carcinogenic, while selenium can interfere with the metabolism of some carcinogens, thus having anti-cancer effect.
3. Change cell metabolism, so as to reduce the damage effect of carcinogens on DNA.
4. inhibit the synthesis of methionine and egg autoplasm in cells and reduce the proliferation rate of cancer cells.
5. the effect of selenium on prostaglandin synthesis, which plays an important role in tumor occurrence or regulation.
6. Selenium can selectively inhibit the synthesis of proliferating protein and DNA replication of tumor cells, thus inhibiting the growth of cancer cells and achieving the effect of cancer inhibition.
