Talk to your doctor before using tamoxifen with soy products. There is some evidence that substances present in soy may stimulate breast tumor growth and interfere with the action of tamoxifen, although this has not been proven. Whether soy products are effective for hot flashes is also uncertain. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor. lasix washout renal scan Women with breast cancer often experience severe joint pain as a consequence of treatment with aromatase inhibitors like Tamoxifen. Researchers in Barcelona suggest that vitamin D supplementation can prevent or at least reduce the pain. This is important because severe arthralgias often limit a woman’s willingness to complete tamoxifen treatment. Daniel Prieto-Alhambra and colleagues at the Hospital del Mar, studied a cohort of 290 breast cancer patients undergoing treatment with Tamoxifen or another of the aromatase inhibitors (AIs). At baseline, 90% had serum vitamin D levels under 30 ng/ml, which is considered deficient in sunny Spain. All the patients were given 800 IU/d vitamin D, but those who were deficient also got an additional 16,000 oral boost every two weeks. Among the women who were pain-free at baseline, those who reached serum levels of 40 ng/ml were 50% less likely to experience drug-associated joint pain than those who remained vitamin D deficient.

"The effects of vitamin D on breast cancer cells are very similar to the established drug Tamoxifen. If you have been prescribed tamoxifen for breast cancer, you've likely heard that it can interact with some other medications. Since these interactions involve commonly used drugs and include over-the-counter and nutritional supplements, this is very important. In addition, you will likely be taking the medication for at least 5 to 10 years, making an awareness of possible interactions not just a momentary concern. It's been thought that there are some people who, due to genetic differences, may not benefit from the usual dose of the drug, but more recent research suggests these women do just as well with treatment. Tamoxifen is broken down into endoxifen by the cytochrome P450 enzyme CYP2D6. (There are also other enzymes such as CYP3A4 and others, but CYP2D6 is likely most significant). Anything that reduces the activity of this enzyme (CYP2D6) can result in a reduced amount of the active metabolite, and hence, less benefit. Reduced activity of the enzyme may occur if you are taking some other medications or if you have particular genetic variations that make the enzyme less active. Vitamin D regulates the flow of calcium into the bloodstream and is crucial for normal bone development. Vitamin D also has a role in regulating parathyroid, neuromuscular, immune, and insulin functions. Vitamin D has been found to be associated with lower risks of cardiovascular disease and age-related cognitive impairment, as well as Hodgkins and non-Hodgkins lymphoma and esophageal, lung, pancreatic, renal, colorectal, endometrial, prostate and ovarian cancer. Vitamin D influences breast cancer development and progression in important ways, but the relationship is not fully understood. Vitamin D influences the expression of breast cancer-related gene activity, including cell differentiation, cell growth, and angiogenesis, all of which are related to cancer development and progression. The impact of vitamin D on breast cancer is influenced by VDR genotype; women can have one of several variants in the VDR gene and these gene polymorphisms influence the potential anticarcinogenic effects of vitamin D. The effect of vitamin D on breast cancer risk is also modified by the level of calcium consumed since various combinations of calcium and vitamin D can have differing effects on cellular proliferation and differentiation. One study found that certain VDR genotypes are associated with lower risk of breast cancer in women consuming high levels of calcium.
