selenium for breast cancer

Selenium and Breast Cancer Risk: Focus on Cellular and Molecular Mechanisms - ScienceDirectWhat is the relationship between selenium cancer and breast cancer? Selenium and breast cancerSelenium is an essential nutrient for human health. And as an antioxidant, it can help combat the disease. Some suggest that a low level of selenium may increase your risk of developing certain cancers. Many studies have been conducted to find out whether there is a link between selenium intake and the risk of breast cancer in particular. Another area of research is whether the selenium of dietary supplements has the same effect as the selenium we get from food. As with many vitamins and minerals, it is possible to get too much of a good thing. Continue reading to learn more about how selenium can relate to breast cancer and what you need to know before taking selenium supplements. is a natural trace element. The inorganic forms (selenite and selenate) are found on the ground. Plants make it organic (eselenomethionine and selenocysteine). Selenium is critical for good health, helping with: Your recent consumption of selenium can be measured in blood and urine. Long-term intakes can be measured in the hair and nails. His body does not make any selenium on its own. You must get him out of the food, but you just need a small amount. Your (RDA) depends on your age. It's measured in micrograms.

You will find it in foods like: Brazil nuts are particularly high in selenium. A single Brazilian walnut can have up to 68 to 91 selenium micrograms. However, the regular high consumption of Brazilian nuts or general selenium can lead to the toxicity of selenium. On the other hand, selenium deficiency can lead to:In the United States, selenium deficiency is . Most of us can get everything we need from our diet because we eat food from many sources. Exceptions may be people who:Some foods have added selenium. Selenium has some properties that help prevent certain types of cancer. Exactly how I could do it is not clear. It may have something to do with antioxidant properties that reduce damage to DNA. Some have not found association between selenium and breast cancer. Some have been inconclusive, but other studies seem to indicate some kind of association. Here are some:In 2013, the United States Food and Drug Administration (FDA) allowed selenium dietary supplements to be indicated, "some scientific evidence suggests that selenium consumption could reduce the risk of certain forms of cancer... The FDA has determined that this evidence is limited and not conclusive. " The agency that needs more research to confirm the relationship between the risk of selenium and cancer, as well as whether supplements are useful to prevent any form of cancer. If you take a multivitamin with minerals, it may contain selenium. Selenium is also available as an independent supplement. If you have breast cancer, it is important to talk to your oncologist before taking selenium or any other dietary supplement. Some may interfere with your treatment or cause other problems. FDA does dietary supplements, but as food — not as drugs. That means they don't go through the same safety and effectiveness requirements as the medications. So, if you decide to take a supplement, be sure to find a trusted source. There have been cases where free-sale products were poorly marked and had very large amounts of selenium. One occurred in 2008 when at least 201 people had severe adverse reactions from a dietary supplement of selenium. It had more than 200 times the amount shown on the label. Some of the first signs you are taking too selenium are a metallic taste in your mouth or a garlic smell in your breathing. Chronic selenium intake is called selenosis. Some of the signs and symptoms are: Beware if you plan to take extra selenium in the form of dietary supplements. Acute toxicity of selenium may lead to:Selenium may also interact with some medications, such as the Cisplatin chemotherapy drug. Talk to your doctor immediately if you are experiencing symptoms of selenium overdose. Research on selenium and breast cancer is intriguing, but many questions remain. You probably have all the selenium you need from your diet. If you have questions about how much you are receiving or if you should take supplements, it is worth a discussion with your doctor or pharmacist.

Triple-negative Breast Cancer (TNBC)Genes Tied to Selenium's Cancer BenefitsSelenium supplements may reduce the risk of breast cancer by 16 June 2003 -- A person's genes can determine whether supplements can reduce the risk of . New research suggests that people with a certain genetic variation can benefit more from taking the popular nutritional supplement to reduce their risk. Selenium is a trace element that is naturally found in foods like nuts and . Researchers say that for more than 20 years animal studies have suggested that small amounts of selenium in the diet can reduce the risk of several organs, but much less is known about the anti-selenium benefits in humans. "We believe that there are certain proteins in mammal cells that can mediate the protective effects, but trying this is difficult," says researcher Alan Diamond, professor and head of human at the University of Illinois in Chicago, in a press release. DNA decoding for differences In this study, published in the June 15 research number, researchers examined the role of a particular protein containing selenium works. "The way we studied this was to see a certain gene that contains selenium that encodes proteins that contain selenium, then examines its nucleotide -- or genetic code -- for differences," Diamond says. "We have sought to see if there were differences in the frequency of the versions of these genes both in tumor cells and in the DNA of people who did not have cancer." They compared the gene in 517 healthy and cancer-free people with 79 breast cancer tissue samples. Researchers found that a certain version of the gene was associated with a higher risk of cancer. That same gene was also less sensitive to the stimulation of selenium. The diamond says it means that people with this genetic variation can benefit from selenium but require a higher dose to achieve the protective effect of selenium against cancer. Although it is too early to recommend selenium to reduce the risk of cancer for the general population, Diamond says that someday genetic testing can allow doctors to prescribe selenium supplements accordingly to those who would benefit most.
